65153	In some cases when annotating schematics, an Access Violation (at address 00000001403B6B00 in module "WorkspaceManager.DLL") would be encountered.
65691	In some cases, attempting to move a placed component off of a schematic sheet (beyond the sheet's border) was not possible, depending on the rotation of the component.
66246	When attempting to multi-select a placed sheet symbol's designator and file name, the error "Exception has been thrown by the target of an invocation..." would be encountered.

PCB

23643	The violation overlay was not being displayed over solid polygon pours detected to be in violation of a 'Modified Polygon' design rule.
53495	When attempting to copy and paste formatted text from Microsoft Outlook/Word into a PCB document, an Access Violation (in module 'ADVPCB.DLL') would be encountered.
64315	When copying and pasting a via (without keeping the same net), the subsequent dialog with which to choose a net (to apply to the via) would freeze for a considerable length of time.
65486	When entering an expression into the Filter region of the PCB/PCBLIB Filter panel, the sorting of entries in a pop-up listing is now correctly sequential "1, 2, 3, 4, 5,..." instead of "1, 10, 2, 20, 21,...".
65622	As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with a selected Embedded Board Array object, to increase performance and optimize access to object properties, especially with larger designs.
65727	When generating IPC-2581 (revision B) fabrication output from a PCB, polygon cutouts placed on power plane layers were incorrectly interpreted and exported as solid copper regions.
65744	When generating IPC-2581 (revision B) fabrication output from a PCB, keepout regions placed on the Top and Bottom layers were incorrectly interpreted and exported as solid copper regions. (BC:20905)
65757	Export of a PCB document to 'Protel PCB 2.8 ASCII' format was not working. The exported file contained no board data. (BC:25468)
65821	As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with PCB library properties (when no objects are selected), to increase performance and optimize access to properties, especially with larger designs.
65905	As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties region of the Polygon Pour Manager dialog has been enhanced when working with a selected polygon pour, to increase performance and optimize access to properties, especially with larger designs.
65906	As part of the PCB.Performance.InteractivePropertyPanel.Optimization option (Advanced Settings), the Properties panel has been further enhanced when working with a selected OLE/connection line object, to increase performance and optimize access to object properties, especially with larger designs.
65987	The relative Delay for each type of primitive is now calculated and stored to cache, facilitating a performance boost in Delay calculation when reopening a design and selecting a primitive for the first time.
66011	When interactively routing a differential pair and switching from the current pad/track to the target pad/track (using the '9' keyboard shortcut), an infinite-looping error "Second differential pair primitive could not be found" would be encountered. (BC:25634)
66072	With the Trace Loop Removal feature enabled, routing from an existing track to an unconnected pad (of the same net) would incorrectly remove existing track-to-pad routing.
66099	The 'QR and Data Matrix Code Support' feature, delivered by the PCB.QRCodes option (Advanced Settings), is now officially made Public with this release (ON by default).
66162	The 'Optimized Online DRC Processing' feature, delivered by the PCB.DRC.OnlineOptimization option (Advanced Settings), is now officially made Public with this release (ON by default).

66206	Pads with different countersink and counterbore hole sizes were incorrectly assigned the same diameter tool in the PCB panel (in its Hole Size Editor mode) and in generated NC Drill output. (BC:25445)
66234	With a Net Antennae rule scoping a specific net, the PCB Rules and Constraints Editor dialog's 'Test Queries' feature erroneously reported zero applicable objects.

Constraint Manager

64692	When defining constraints for a clearance rule, clearance values for Top Layer and Bottom Layer were incorrectly being inherited from Inner Layers instead of Outer Layers.
65614	When defining constraints for a clearance rule, custom clearance values set for Outer Layers were being reset to defaults when changes to values for Inner Layers were reset to their defaults.
65837	In some cases while working with the Constraint Manager, the error "System.NullReferenceException: Object reference not set to an instance of an object" would be encountered.
65976	In the All Rules view of the Constraint Manager (when accessed from the PCB), a warning and related highlighting has been added for a rule that contains a syntactically incorrect custom query expression and is therefore deemed invalid.
66073	After switching from the 'Default Stack' to a specific PCB and defining a clearance set, it was not possible to subsequently remove any assigned constraint sets. While they could be removed in-session, saving-closing-accessing the Constraint Manager would show them still present.

Draftsman

62223	In some cases when working with a Draftsman document, the error "EOleException: Board not found" would be encountered.
65923	Row visibility settings for a placed transmission line table were incorrectly being changed when importing changes from the linked PCB document and also when generating PDF output through an OutJob file. (BC:21909)

CAMtastic

65878

For ODB++ fabrication output generated from a specific panelized board, some drill drawing data for the panel was not being presented in the CAMtastic document.

3D-MID Design

65823	After initially importing components into a 3D-MID document (via ECO), attempting to move multiple selected components from free space onto the 3D substrate would result in an Access Violation (in module 'A3dEntry.dll') being encountered and, in some cases, forced closure of Altium Designer.
66105	The commands to 'Show All' and 'Hide All' net connection lines (on the View » Connections menu) were no longer working.

Multi-board Design

64950	Added the ability to define an 'Inline Harness Connector' on a multi-board schematic, splitting an existing harness connection into two.
65591	In a specific case, attempting to remove an entry connected to a harness on a multi-board schematic document would result in the error "Object reference not set to an instance of an object" being encountered.

Harness Design

61560	When placing a linear dimension between connection points on a layout drawing view placed in a Harness manufacturing drawing (*.HarDwf), the value used for the 'Value' field (the length of the dimension) is now automatically filled with the corresponding bundle length.
65236	In some cases after freely positioning/rotating designators and parameters in the layout drawing (with their 'Autoposition' option disabled), they would be rotated/moved after importing changes from the wiring diagram.
65344	In some cases when working with a harness design's wiring diagram, the error "EOleException: One or more errors occurred. (Object reference not set to an instance of an object.)" would be encountered.
65723	Added full support for using Harness Wiring Templates (in a harness wiring diagram) and Harness Layout Templates (in a harness layout drawing), both local and Workspace-based, using the commands available from the respective editor's main Design » Sheet Templates menu.

Platform

66056	The command to access the Storage Manager was not always available from the right-click context menu for project documents in the Projects panel.
66161	When configuring synchronization options between schematics and PCB in the Differences between dialog, the 'Update Same Kind in...' commands were no longer functional.

Data Management

56236	Where a reuse block placed on a schematic contained a component where a pin had been mapped to multiple footprint model pins (pads), the block was not transferred correctly from the schematic to the PCB.
65339	For a variant of a design using an alternate component, when attempting to update that alternate component to its latest revision, through the Item Manager, the wrong component (base, non-varied component) would be updated. (BC:21074, BC:22150)
65699	When editing a Workspace component as a user with view-only permissions, the Component editor will now always open, giving you the ability to access component details and make local edits, but with the inability to save/release any changes back to the connected Workspace.
65711	When using a control to rename an entity anywhere in the software (e.g., a project or one of its documents), a couple of improvements have been made to the subsequent Rename dialog. Firstly, clicking OK without making a change to the current name will behave as though having clicked the Cancel button. The error "<Name> already exists" will no longer be encountered. Secondly, you can now change the case of characters in a name (e.g., renaming from 'Myexamplepcb.PcbDoc' to 'MyExamplePCB.PcbDoc').
65894	After renaming a Workspace project's PCB document and at some later stage reverting back to a revision of the document prior to the renaming, a subsequent attempt to compare the local document against the head revision in the remote (Workspace's Git) repository, would result in the error "Cannot find the common ancestor..." being encountered and data being lost.
65914	Added a notification for any issues relating to the WebSocket notification channel, when connected to a Workspace. Note that this notification appears only if the EDMS.ConnectivityMonitor option (Advanced Settings) is disabled. When this option is enabled, Altium Designer just disconnects from the Workspace when there is no Internet connection.
66278	With a variant selected in the Projects panel it was not possible, from the project's ActiveBOM, to update an alternate part to its latest revision using the 'Operations » Update to the Latest Revision' command from the right-click context menu (BC:22498)

Import/Export

63453	When importing a specific Allegro design, the solder and paste masks were missing for a few pads in the generated PCB document. (Requires the Importer.Allegro.ReadPadLayers advanced settings option to be enabled).
65409	When importing an OrCAD design with the 'Convert Orcad Off-Page connectors as Altium Ports' option enabled, a bidirectional off-sheet connector would be incorrectly imported as an 'Unspecified' port.
65924	In some cases when importing an OrCAD design, port names were being placed incorrectly on a generated schematic document.
66015	When exporting a PCB into Ansys EDB format, resistor values specified in MOhm were being incorrectly exported in mOhm.

Circuit Simulation

65346

In some cases when working with the Mixed-signal Circuit Simulation feature, the error "EOleException: Could not find a part of the path "C:\ProgramData\Altium\Altium Designer {0E86C1C9-72CF-4BA0-A887-5B3AC0C1E1D4}\Extensions\Mixed Simulation\Library\SPICE models"" would be encountered.

SI Analyzer by Keysight

65544

The SI Analyzer was not considering the Solder Mask in its calculations, when the 'Use Solder Mask' option was enabled as part of the Transmission Line properties for the Layer Stack Manager, leading to an incorrect impedance value when compared to that returned by the Layer Stack Manager (simulated by the Simbeor software).

Version 25.7.1

Build: 20 Date: 11 June 2025

Schematic

64824	In some cases after updating an outdated component through the Item Manager, attempting to cross-probe to the reference part (using the 'Cross Probe - Reference Part' command from the ECO dialog's context menu), an Access Violation (in module "WorkspaceManager.DLL") would be encountered.
65693	After placing a port and connecting to a wire (with direction towards the wire), renaming the port with a lengthier name would result in the port auto-sizing to accommodate but extend it over the wire, breaking the electrical connection (becoming disconnected from the wire). (BC:22330)
65876	The position of cross-reference information associated to a port (positioned to the right or above the port) was not automatically adjusted when the port was resized. (BC:25532)

PCB

55542	When using the auto-save feature (Data Management - Backup page of Preferences) and setting the Path to a directory for which there is no permission to create folders/files, the error "STG: Access Denied..." would occur when attempting to backup the open PCB document.
60957	The Properties panel has been enhanced when working with various types of selected objects, to increase performance and optimize access to object properties, especially with larger designs. (BC:22364, BC:24767)
64846	In a specific case, it was not possible to open a project's PCB document, freezing at the stage of "Rebuilding connectivity database...". (BC:24986)
65341	Greatly improved the reaction time when activating/deactivating layers, one after the other or a whole group, within the Layers & Colors tab of the View Configuration panel.
65620	Donut-shaped pads were not mirrored in PDF output when the "Mirror layers" option was enabled as part of print properties. (BC:25241)
65708	In some cases after executing the initial ECO to push a design to the PCB, some components were being placed far from the board's origin.
65738	For a specific panelized board, the annular rings for pads on certain Mid layers were not being displayed.

PCB CoDesign

65319	The shortcut to enable the PCB CoDesign panel's 'Show on PCB' option has been changed from Shift+A to Ctrl+Shift+A with this release.
65321	The 'Zoom selected object' option is now disabled in the PCB CoDesign panel by default.
65965	In some cases when running a comparison, the error "Cannot get the latest revision..." or "Cannot find the common ancestor..." would be encountered.

Constraint Manager

64579	In the Clearances view (accessed from schematic), a cell whose value had been previously loaded with a chosen constraint set would not clear that 'set entry' when either setting the value for the constraint set to 'None Selected' or entering a custom value, and then saving/closing/re-accessing the Constraint Manager.
65340	The Constraint Manager is now automatically refreshed with changes made to rules/classes on schematics when pushing changes from the schematic to the PCB (at the time the ECO dialog is accessed), without having to access the Constraint Manager and perform a refresh there. Note that if the Constraint Manager view is already open, this synchronization will only occur provided no unsaved changes have been made. (I:23779)
65362	It was not possible to define a custom xNet topology within the Constraint Manager when accessed from the PCB.
65488	It was possible to resize the bottom section of a view in the Constraint Manager too far, resulting in the content of the top area appearing 'invisible' and therefore not editable. (BC:25699)
65611	When defining constraints for a clearance rule, custom clearance values set for Inner/Outer Layers were not being reflected correctly (the min-max range) in the upper section of the Clearances view.

Draftsman

59671	When placing linear dimensions within a Draftsman document, the hardcoded tolerance between parallel line segments has now been reduced from 0.8 degrees to 0.08 degrees.
65625	For a specific PCB design, attempting to save its manufacturing drawing document (*.PCBDwf) after placing a drill drawing view, transmission line table or drill table, would result in the error "Value cannot be null. (Parameter 'key')" being encountered.

Harness Design

59312	On the Wiring Diagram, dragging wires that have visible parameters (but Autoposition disabled) would create splices at the original parameter-wire connection points that could not be removed with Undo. (BC:25759)
65059	For a design including one or more harness components with undesignated pins, attempting to place a layout drawing view into the harness manufacturing drawing document (*.HarDwf) would result in the error "Value cannot be null. (Parameter 'key')" being encountered.
65140	In some designs, after importing changes from a wiring diagram into the layout drawing, from/to information for wires and cables would be lost.
65337	For a specific harness design, even though Strip Length information was present for defined crimps in the wiring diagram and layout drawing, after importing to the project's Draftsman document, no information was present for the 'FromCrimpStripLength' and 'ToCrimpStripLength' columns in the wiring list. (BC:25491)
65612	In the wiring diagram, a placed wire (of type 'Standard (No BOM)') was still being presented in the BOM if it was connected through a wire break.
65613	A wire would appear multiple times in a wiring list (in the harness manufacturing drawing) if it was connected through a wire break to multiple parts of a multipart harness component.

Platform

65849

When using the 'Open All' or 'Open All Schematic Documents' commands, a message and progress bar are now displayed.

Data Management

63891	In some cases when working with the Component editor, the error "EInvalidAccessToObject: Object accessed after being destroyed. Adapter class: TModelChoiceAdapter" would be encountered.
63928	Added support for multi-select fields when creating a Jira task through Altium Designer. Now, you are presented with checkboxes with a warning to select at least one option to continue.
65203	Added the ability to work with multiple Workspace components as a 'group' (from the Projects panel), in terms of opening, closing, saving locally, saving to the connected Workspace, or discarding changes (closing without modification).
65226	When browsing components in the Explorer panel, data on the 'Preview' aspect view did not update/refresh when switching between components using the up/down arrows on the keyboard. (BC:24578)
65444	The 'Leave Feedback' link has been removed from the bottom of the Comments and Tasks panel.
65589	After using a command to remove a Managed Output Job from a project locally, it was not being removed from the connected Altium 365 Workspace's 'Versioned Storage' Git repository. On saving the project back to the Workspace, there was no 'scheduled deletion' option in the Save to Server dialog.
65632	Altium Designer would 'freeze' for several minutes when attempting to delete a large number of selected components in the Components panel. (BC:25114)
65803	Added support for using commenting and tasks features in a Multi-board Assembly document (*.MbaDoc).

Import/Export

63452	When importing a specific Allegro design, free text objects on the a silkscreen layer were missing.
64974	Added the ability to import more detailed pad stack information when importing an Allegro design, using the advanced settings option 'Importer.Allegro.ReadPadLayers'.
65504	In some cases, importing multiple Allegro library files (*.dra) at once would result in silent termination of Altium Designer, without any libraries being imported.
65626	When importing a specific xDX Designer design, bus entries were being imported incorrectly.
65867	When importing an Allegro design, if a polygon pour is less than 2500 sq.mil in size, its ‘Remove Islands Less Than’ option will automatically be disabled.

Version 25.6.2

Build: 33 Date: 14 May 2025

Schematic

47721	When opening Altium Designer after closing with a schematic still open in the previous session, holding the right-hand Ctrl key down during launch would result in an Access Violation (in module 'AdvSch.dll') being encountered.
59536	When opening any schematic document in a PCB design, the whole document was not made to optimally 'fit' within the extents of the design window by default.
64649	After using the Properties panel's Smart Edit Batch Replace feature for multiple selected string-based objects of the same type (e.g., ports, text strings, etc.) on a schematic, clicking away from the selected objects would incorrectly replace them all with the name of the first object in the selection (the name displayed in the Properties panel after the batch replace). (BC:24501)

PCB

61438	Added support for generating a list of nets and copper primitives that are intentionally allowed to short ('Net-Ties') when generating ODB++ V8.1 output
61957	In some cases when interactively routing to connect 'hanging' ends of a differential pair in 'Any Angle' mode, artifacts would be present in the design space and an Access Violation (in module 'RouterEntry.dll') could be encountered.
64430	With the PCB.EnableTraceCentering option enabled (Advanced Settings) and the 'Disable Trace Centering When Dragging' option enabled (on the PCB Editor - Interactive Routing page of Preferences), noticeable lagging/delay was experienced while sliding a diffpair (in HugNPush Obstacles mode) toward a cluster of other diffpairs.
64960	In some cases, component custom pad copper regions were being removed when interactively sliding associated track.
65225	The 'ODB++ v8.1 Intentional Shorts' feature, delivered by the ODB.IntentionalShorts option (Advanced Settings), is now officially made Public with this release (ON by default).
65270	In a specific design when applying teardrops, the straight Line style would be applied instead of the chosen Curved style.
65411	In some cases when interactively routing with all loop removal options enabled, a loop would be removed but associated vias would incorrectly remain. (BC:25286)
65422	In some cases when re-routing differential pairs in 'Line 45/90 With Arc' mode, an Access Violation (in module "ADVPCB.DLL") would be encountered. (BC:25260)
65462	After turning off the visibility of one or more objects for a PCB in Altium Designer, those objects were not being presented in the 2D PCB view, when viewing the board through the connected Workspace's browser-based Web Viewer. (BC:25196)
65528	When adding shielding to a net using µVias, µVias were being skipped (not placed) if they overlapped µVias in shielding on the opposite side of the board. (BC:23639)
65603	The 'Enhanced Layer Stack Report' feature, delivered by the PCB.ModernBoardStackGenerator option (Advanced Settings), is now officially made Public with this release (ON by default).
65633	After placing a dimension object on any layer other than the Top Layer, double-clicking on it and then pressing Esc, would result in its layer changing to the Top Layer.
65710	While viewing the properties for a board, deleting a grid and then clicking on the Properties button for the Grid Manager section, would result in an Access Violation (in module ‘ADVPCB.DLL') being encountered.
65761	After saving a PCB, restarting Altium Designer and reopening the PCB, the value for the Delay field (in the Net Information region of a selected track's properties) would no longer be calculated. (BC:25482)

PCB CoDesign

64798	Enhanced working with the differences and conflicts sections of the PCB CoDesign panel. In both sections, keyboard shortcuts are now available for traversing the list (Up Arrow/Down Arrow) and expanding/collapsing a section (Spacebar). In addition, and for the conflicts section, switching between Local/Remote is now possible using Left Arrow/Right Arrow.
65322	In the PCB CoDesign panel, when choosing whether to apply a local or remote change, you now have the ability to quickly set 'Local' or 'Remote' for all changes in a specific category. In addition, you can also quickly apply the desired setting to all currently selected change entries.

Constraint Manager

63370	Improved the way in which a Clearance rule is imported to the Clearance Matrix when migrating from the old design rules system for a project. When first and second scope expressions are set to 'All', the net scope / connective checking option (Different Nets Only/Same Net Only/Different Differential Pair/Same Differential Pair) is now taken into account.
64061	Added the ability to Undo/Redo changes made within the Constraint Manager.
64394	For a differential pair directive that is attached to a blanket, after syncing/importing with/to the Constraint Manager, it is now possible to toggle the display of diff pair class and associated rules information in the design space.
64489	Values for clearance rules in the All Rules view (accessed from PCB) were not synchronizing correctly with clearances specified by constraint sets (assigned to nets, net classes and rooms) in the Physical view.
65432	The units of measurement presented for new constraint changes in the ECO dialog did not follow the units of measurement defined for the PCB, when passing changes from schematic to PCB.

3D-MID Design

65276

Routing on a 3D substrate would become noticeably slower after enabling the alignment grid (and remain so after disabling it again).

Harness Design

61029

For a specific harness design featuring wire breaks and splices, validating the project would result in erroneous duplicate designator and orphaned wire violations. (BC:24832)

63103

Added a new advanced settings option 'HarnessDesign.Embed3DModel' that, when enabled, embeds 3D models (Parasolid format) in the layout drawing document. Each 3D model is created when adding a Physical View for a harness component or connection point. Any missing 3D models (existing but not embedded) will be embedded after saving the layout drawing. This feature facilitates improved integration when using Altium MCAD CoDesigner with harness design projects.

Platform

65204	The 'Purchased' tab of the Extensions and Updates view has been renamed to 'Available', to better reflect that this tab presents additional functionality and features (delivered by extensions) that are available to you, but have not yet been installed. Similarly, the option 'Purchased but not installed' has been renamed to 'Available but not installed'. Note that while all extensions can be installed, some functionality may require additional purchase/licensing to fully use.
65306	Updated the link text - from 'Learn More' to 'Contact Us to Discuss Your Options' - in warning messages that appear in, for example, the License Management UI for perpetual licensing whose subscription is expiring (or has expired). To reiterate, subscription renewals are no longer available for perpetual licenses. After expiration, a perpetual license can still be used, but you won't have access to later updates for Altium Designer beyond that point (no new features/functionality), nor will you have access to cloud capabilities delivered through, and by, the Altium 365 platform.
65309	Perpetual licenses, irrespective of their subscription state, are now always displayed on the License Management view and are no longer hidden when the 'Hide Expired Licenses' option is enabled.
65314	In some cases when connecting to an Altium 365 Workspace, the error "System.ServiceModel.Security.SecurityNegotiationException: Could not establish trust relationship for the SSL/TLS secure channel with authority..." would be encountered.
65315	In some cases when connecting to an Altium 365 Workspace, the error "System.ServiceModel.CommunicationException: The SSL connection could not be established, see inner exception..." would be encountered.

Data Management

59692	The number of characters that can be entered into a standard comment and task is now limited to 2000. In addition, and when posting/replying to a Jira-related comment, the number of characters has been extended to 20,000.
63220	In some cases when working with comments, the error "EOleException: Object reference not set to an instance of an object" would be encountered.
65082	When editing an existing Workspace component in the Component editor (in its Single Component Editing mode), it was not possible to save changes back to the Workspace if the editor had been opened in a separate window.
65130	In some cases when connecting to an Altium On-Prem Enterprise Server whose session has expired, "401/unauthenticated" errors would be encountered. As a result, any opened projects (from the Enterprise Server) were not getting refreshed correctly with respect to showing which collaborators were actively reading/editing documents.
65155	In some cases when saving a part from the Manufacturer Part Search panel to a connected Workspace, changing the parameter mapping of a unit-aware parameter to something that is not correct unit-wise, would result in Altium Designer silently crashing without message or warning. (BC:25341)
65160	In some cases when working with the ActiveBOM, the error "ERangeError: Range check error" would be encountered.
65208	When using the Project Releaser and generating assembly data for a variant of a design containing a component with a specified alternative part, the 'Children' aspect view of the released Assembly item (as viewed through the Explorer panel) was incorrectly including the main component (in addition to the alternative part).
65338	Using the Item Manager, it was not possible to update to the latest revision of an alternate Workspace component used in a variant of a design. The ECO would always fail to execute. (BC:24393)
65398	With local file locking applied ('Enable File Locking' option enabled on the Data Management - File Locking page of Preferences), attempting to save changes to an existing Workspace component from the Component Editor resulted in a catastrophic failure "The process cannot access the file because it is being used by another process" being encountered. (BC:25017)

Import/Export

63510	After importing a specific xDX Designer design, its Title page was missing a logo image and associated template information (containing title block, zone information, etc.).
64093	When importing a specific xDX Designer design, power ports were being imported incorrectly.
64161	After importing a specific xDX Designer design, it was not possible to resolve "Missing Harness Type on Signal Harness" validation errors.
64211	For a specific Allegro design, after importing and generating a PCBLib from the PCB, updating particular placed components from that library would result in their footprints becoming rotated by 180 Degrees, causing short circuits.
64645	When importing an xDX Designer design, a new option has been added that allows you to import 'off-page' connectors in the source design as ports on the generated schematic documents, rather than default off-sheet connectors.
65132	When importing an Allegro design and library, the generated PCB used the center of each footprint as the origin, while the generated library used the center of a footprint's pin 1 as the origin. When using the 'Update From Libraries' command, components would be incorrectly positioned as a result.
65253	For a specific xDX Designer design, sub-parts of a multi-part component were missing after import.

Version 25.5.2

Build: 35 Date: 16 April 2025

Schematic

50893	The use of the left square bracket character ([) in a text string was not being evaluated correctly in a text string placed on the schematic. (BC:18861)
64732	In some cases in a multi-channel design, with the 'Ports' option enabled in the 'Compiled Names Expansion' region of the Schematic - Compiler page of Preferences and the 'AutoSize' option enabled for a placed port, the size of the port would change after switching to the compiled schematic (physical) tab and back to the Editor (logical) tab.
64869	For a selected graphic image on a schematic sheet and with the 'X:Y Ratio' option enabled in the Properties panel, changes to the image’s width or height from within the panel were not being automatically detected, resulting in the aspect ratio not being kept 1:1. (BC:24890)
65330	The feature to provide a clear display of text and other drawing objects that overlap a graphic image when generating a PDF from your schematics, delivered by the Schematic.ExportPDF.UseBitmapTransparency option, and the 'Auto-addition of Supply Nets Rule' feature, delivered by the Schematic.AutoGenerateSupplyNetsRule option (Advanced Settings), are now officially made Public with this release (both ON by default).
65352	For a specific PCB design project, attempting to select multiple objects on a schematic when the Properties panel was open, would result in the error "Exception has been thrown by the target of an invocation..." being encountered. (BC:25148)

PCB

56173	In some cases, an Access Violation (at address 00007FFBBD5E84DE in module "Altium.PCB.DataModel.X.dll") would be encountered.
61497	Added an Advanced Settings option (PCB.DRC.OnlineOptimization) that when enabled, optimizes Online DRC processing.
64117	In some cases when applying teardrops, the straight Line style would be applied instead of the chosen Curved style. (BC:24557)
64138	In the specific case of a large design, via selection and panning within the design space were considerably slow, with moments of severe 'lag' being experienced.
64462	The Applicable Binary Rules dialog now shows the relevant net classes applicable to a clearance constraint, as configured in the Constraint Manager, in the form "<NetClass> to <NetClass>".
64719	A PCB layer mismatch would result when copying-pasting vias/pads between PCB-to-PCB (and where signal layers have been moved in the target PCB layer stack) or between PCBLib-to-PCB (and where signal layers have been moved in the source PCBLib layer stack). Data for the pasted vias/pads was not respecting the layer stack configured in the source document in each case. (BC:20707)
64752	Net information (Length and Delay) is now stored with the PCB document, allowing for better performance when opening the PCB and when accessing information through the Properties panel and heads-up display.
64964	When exporting a PCB document to STEP 3D format, if the PCB includes a Route Tool Path layer with zero-width arcs placed on it, an Access Violation (at address 00000001A1E10BBC in module 'OUT_ExportStep.dll') would be encountered. (BC:24989)
65058	With the 'Allow variation for paste mask' option enabled for a project variant, custom-shaped pads for a 'Not Fitted' component were still being included in Gerber output for the paste layer. (BC:25007)
65106	In some cases when switching active document to the PCB, an Access Violation (at address 0000000178B71550 in module "ADVPCB.DLL") would be encountered.
65151	In a specific case while interactively routing with the Auto Shrinking option enabled, a trace would not shrink to its minimum allowed width (per applicable constraint) when passing between BGA pads. (BC:25143)
65366	The 3D preview for a component footprint would not be visible (e.g., in Schematic Library editor, PCB Model dialog, Components panel) if that footprint contained a bond wire primitive.
65439	When exporting a single layer PCB to Parasolid format, with Copper Export Options set to 'Export All' or 'Export Copper Only', the error "Item not found" would be encountered and Altium Designer would terminate.
65466	In some cases when placing vias from a Pad/Via Template library, the error "COM object that has been separated from its underlying RCW cannot be used" would be encountered.
65483	With the 'PCB.SingleLayerStack.Support' option enabled (Advanced Settings), signal/plane layers were getting renamed 'Top Side'/'Bottom Side' when moving a signal/plane layer down/up within the Layer Stack Manager.

PCB CoDesign

63798

In a specific case, after changing the layer for a component with wire bonding in one PCB instance, when that change was merged into another PCB instance, one of the bond wires was not attached to that component's corresponding die pad.

Constraint Manager

60767	In some cases and with the Constraint Manager accessed from the schematic, it was not possible to set a 'Tolerance' or 'Matching Target' value for specific xSignal classes.
63736	Introduced the notion of an 'xNet diff pair', an element that exists only within the Constraint Manager. With this feature, you now have the ability to create diff pairs from xNets, from within the Physical view or the Diff Pairs tab of the Electrical view of the Constraint Manager (when accessed from either a schematic or PCB).
64743	In some cases when working with the Constraint Manager, the error "System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter "index")" would be encountered.
64875	Added support for exporting/importing Advanced Rules (when accessing the Constraint Manager from the PCB). When imported, associated custom scopes are applied automatically. (Delivers on point 2 of I:22944)
64876	Added a warning to the ECO dialog for the situation where scopes of some classes have changed but are unsynchronized between the source schematics and the Constraint Manager.
64904	New and unique icons have been implemented to distinguish the Constraint Manager when accessed from the schematic and PCB respectively.
64930	With the Constraint Manager open on both sides (schematic and PCB), constraint data changes on one side were not apparent after pushing changes from the other side (through an ECO) and it was not possible to synchronize manually (the Refresh button was disabled). A similar situation also arose when the Constraint Manager was open (from the PCB) and a new clearance rule was being created from the Polygon Pour Manager (in the PCB editor). The new rule was not apparent and, again, the Refresh button was disabled.
64940	When pushing changes to the PCB, the ECO dialog would incorrectly keep including an entry for changes to the clearance matrix (scopes), when no changes had been actually made.
65171	Added 'Expand All' and 'Collapse All' commands to the right-click context menu for an xSignal Class, on the xSignals tab of the Electrical view.

Draftsman

64149	When changing the source for a PCB design's manufacturing drawing document (PCBDwf) from the PCB to the panelized PCB, the error "Object reference not set to an instance of an object" would be encountered.
65305	The list of document parameters is now sorted by default (by Name).

Wire Bonding

63354	Not all bond wires were being displayed when viewing the PCB through Altium 365's Web Viewer interface.
64929	With a PCB in 3D View mode, attempting to select any bond wires would result in the wires not being highlighted immediately, instead requiring a pan or zoom action first.
64941	The 'Wire Bonding' feature, delivered by the PCB.Wirebonding option (Advanced Settings), is now officially made Public with this release (ON by default).
64970	With a PCB in 3D view, after moving a component (with a footprint featuring wire bonding) an additional (and long) bond wire would suddenly appear in the design space.

Multi-board Design

64714	After selecting multiple connections on a multi-board schematic, attempting to cross-probe to the multi-board assembly document would result in the error "Object reference not set to an instance of an object" being encountered.
64766	Where a rotated image has been added to a multi-board schematic and the project saved to a connected Workspace, that image was incorrectly displayed (as not being rotated) through the Workspace's Web Viewer.
64886	The 'Support for External Peripherals/Components' feature, delivered by the MBS.PlacePart and MBS.UseGeometryMaker options (Advanced Settings), is now officially made Public with this release (both options are ON by default).

Harness Design

61279	Added, for the harness covering object, the ability to define Start/End offsets. Using these offsets, in conjunction with the bundle length (segment enclosed), the actual covering length is then calculated, for display in the main design space and the BOM. (I:25002)
62453	Added import of layout drawing document parameters into the associated harness manufacturing drawing document (HarDwf), including calculated parameter values such as '=ItemRevision' and '=ItemRevisionLevel1'. (I:24175)
63923	With the 'Enable Auto Pan' option disabled on the Schematic - Graphical Editing page of the preferences, placing a cable component onto the wiring diagram from a connected Workspace, using the Place command on the Components panel's right-click context menu, resulted in the component being incorrectly placed as a single harness component, rather than separate harness objects.
64077	Harness covering objects were being ignored when running one of the Layout Drawing editor's automated annotation commands (e.g., 'Annotate Harness Layout Drawings Quietly').
64265	Added the ability to define 'Strip Length' and 'Pull Off Length' termination parameters for a 'no connect' object.
64631	In some cases when using the cross-probing functionality in a harness wiring diagram, the error "EOleException: The method or operation is not implemented" would be encountered.

Platform

55153

After choosing a license to use from the License Management view, if network connection was subsequently lost, trying to refresh the view or release the license would result in a hard crash of Altium Designer.

65316

With the Microsoft Windows 'Beta: Use Unicode UTF-8 for worldwide language support' option enabled in the Region Settings dialog, Altium Designer would encounter the start-up error "Load file error: The type initializer for 'Altium.Sch.DataModel.Serialization.Types.StrUtils' threw an exception". Once running, attempting to access any schematic would result in the document opening 'empty', with the error "Failed to load project: Value cannot be null. (Parameter 'encoding')" presented in the Messages panel. (BC:25239)

Data Management

58076	In some cases, loading the footprints of a chosen PCBLib in the Components panel would take a considerable time, with an information dialog ("Please wait a moment...") repeatedly appearing. (BC:21992)
63236	When placing a comment on an applicable document and assigning it as a task, posting it and then resolving it while it was still processing, would result in the error "The HTTP status code of the response was not expected (500)..." being encountered.
63633	In some cases when working with comments, the error "Altium.Services.Comments.Client.ApiException: The HTTP status code of the response was not expected (502)..." would be encountered.
63991	Searching for a component through the Components panel would send too many search requests to the connected Workspace, impacting performance.
64073	When using the BOM CoDesign feature, the Related BOMs section (on the Related BOMs tab of the Properties panel, when accessed from the ActiveBOM document) is now resizable.
64074	When using the BOM CoDesign feature, the 'Show More' control (associated with the Details section, on the Related BOMs tab of the Properties panel) is no longer presented if the full text is already displayed.
64591	When creating a new component without use of a component template, it was not possible to change the component's Id.
64634	In some cases when working with comments, the error "System.NullReferenceException: Object reference not set to an instance of an object" would be encountered.
64763	Added the ability to preview compressed ODB++ data, generated as part of release preparation using the Project Releaser.
64775	Attempting to search for a component using the Components panel and including a comma in the search string, would fail to return that component in the search results. (BC:21907)
64778	Where a project was shared with a user/group whose name was very long, the 'Copy Link' control in the Share dialog would disappear. (BC:23411)
64779	When migrating a PCB design project including a LibPkg file, from an external Git repository to a connected Altium 365 Workspace's internal Git repository, the migration process would fail, resulting in missing files and data loss.
64815	In a specific case and when trying to add a part choice during creation of a new Workspace component, the error "Object reference not set to an instance of an object" would be encountered.
64844	For a displayed VCS Revision in the Storage Manager panel, any comment included at the time of commit no longer presents with an extra, redundant line.
64915	In some cases when attempting to update a project with the latest revision in the connected Workspace, the error "System.ArgumentException: An item with the same key has already been added" would be encountered.
64978	When processing an operation involving a design project in a Git repository, the 'Overall Progress' dialog now appears without adding an additional 'Altium Designer' icon to the Windows Taskbar.
65019	It was not possible to access the 'Project View' for any chosen project in the Explorer panel. (BC:25059)
65105	When using the BOM CoDesign feature and comparing a design project's ActiveBOM with a chosen Related BOM, the DesignItemId is no longer displayed in the Differences section (within the Related BOMs tab of the Properties panel).
65111	When a specific document in a Workspace project has conflicts, the 'Conflict Detected' pop-up now shows the author and timestamp of the user who last modified that document, rather than the user who last committed the project to the connected Workspace.
65125	When attempting to save a design to a connected Workspace and the design includes documents in the 'Ahead of server' state only, these documents are now pushed to the Workspace (instead of committed and pushed), ensuring no 'empty commits' (commits with no real changes).
65511	The 'Part requests' folder is now visible again in the Explorer panel, irrespective of whether access to managed process workflows functionality is available or not. Note that this reverts the functionality implemented by '#64072' in Altium Designer 25.4.

Import/Export

61046	When importing a specific xDX Designer design, ports and power ports were positioned incorrectly on a generated schematic document.
65013	The Xpedition Importer now adds the correct offset when importing an Xpedition design, so that the full design is available for editing in Altium Designer.
65080	For a specific design exported to Ansys EDB (direct or using Ansys CoDesigner), custom-shaped pads in component footprints were being incorrectly exported (flipped vertically) when viewed in Ansys Electronics Desktop.
65162	Added support for the import of essential thermal reliefs (defined in the Allegro Constraint Manager) when importing an Allegro design, facilitating better connection assignment.

Version 25.4.2

Build: 15 Date: 13 March 2025

Schematic

53367	Minor update to the graphics for a device sheet symbol that employs the 'Repeat' keyword (in a multi-channel design). The set of stacked device sheet symbols are now drawn with rounded corners.
57373	Concatenation of special strings with numeric (integer) values would result in unexpected arithmetic operations and ultimately an incorrect overall string being presented. A note has been added to the documentation to clarify that such a parameter value must be placed in single quotes, thereby preventing it from being interpreted as a number and excluding it from any arithmetic operation. (BC:14889)
64110	After using the Alt+click shortcut over a net object (to select that object and to highlight all objects associated to that net across all sheets of the active design project), all other objects on the schematic would remain in a greyed-out state, with no way to clear the highlighting, save for restarting Altium Designer. (BC:24098)
64347	In some cases when working with the Properties panel for a schematic document, the error "System.NullReferenceException: Object reference not set to an instance of an object" would be encountered.
64443	Added visibility of dynamic parameters in the Properties panel for a placed (and selected) component on a schematic, using a combination of two advanced settings options - 'Schematic.UI.ShowMoreOrLessParameters' and 'Schematic.ForceLoadDynamicParametersInIPP'.
64445	For a component parameter whose value includes one or more concatenated special strings, display of the value in a chosen variant would change from real value to "#NAME?" when the component variation was toggled from 'Fitted' to 'Not Fitted' in the Variant Management dialog. (BC:24472)
64549	The 'Report Project Hierarchy' command (on the Schematic editor's main Reports menu) was not functional and did not generate a .rep file, as expected.

PCB

64053	After creating a single layer PCB and placing a layer stack table in the design space, the signal layer would disappear from the table after closing and reopening the PCB document.
64300	For a Rigid-Flex PCB with multiple Flex sub stacks, one on top of another (e.g. Flex Top stack above Flex Bottom stack), the routing width for the Flex Top stack region was not following the applicable design rule value. Instead, the Rigid stack routing width rule value was being used. (BC:23279)
64313	For a specific design, Altium Designer would freeze when attempting to move/drag a particular track.
64567	With the option 'Remove Net Antennas' enabled (PCB Editor - Interactive Routing preferences), net antennas were not being removed as part of the automatic trace loop removal feature. (BC:24867)
64584	Backdrills were being ignored when interactively routing, leading to clearance violations with backdrill vias.
64676	For a specific and large RF design, interactive routing performance was found to be considerably slow.
64699	When exporting a design to DXF format, the paste mask was missing for any pad set to use a predefined or custom shape.
64707	For a specific design with complex outline and large number of cutouts, routing performance was very slow.
64771	In some PCB designs and using the Interactive Router in its 'Follow Mode', track being routed would not actually follow the contour of the board.
64922	It was not possible to access the Edit Room Definition dialog for a placed room, either by double-clicking on the room or by using the Properties command on the associated right-click context menu.
65016	In a specific case and when starting to interactively route a diff pair, an Access Violation (at address 00007FFA06D76588 in module 'RouterEntry.dll') would be encountered.

PCB CoDesign

64624	After a merge failure an error was being encountered, rather than changes being rolled-back and the document being returned to its pre-merge state.
64745	After reverting a merge the document is left in the 'Merged' state, rather than changes being rolled-back and the document being returned to the 'Locally modified' state.

Constraint Manager

63914	For a specific design project, accessing the Constraint Manager from the PCB would take a long time and switching to the Physical view would take far longer still.
64336	The schematic constraints document (Constraints.xml) is now added to the project (on first save of the Constraint Manager) and made available through the Projects panel (in the Settings/Constraints sub-folder). In addition, constraints data in the document is reloaded/refreshed after updating the project from the connected Workspace.
64396	For a PCB design that showed no differences when performing an update to the PCB or running the Differences report output from an OutJob, the Differences report would incorrectly fail during the validation stage of the release process (when using the Project Releaser), flagging changes existing in constraints.
64464	Values for clearance between diff pairs and the gap between sides within a diff pair were incorrect in the Applicable Binary Rules dialog, compared with the values in the Constraint Manager.
64465	For a parameter set directive including a defined net class, after syncing/importing with/to the Constraint Manager, it is now possible to rename the net class from the Properties panel, when the directive is selected on the schematic.
64537	The 'Graphical Custom Topology view' feature, delivered by the ConstraintManager.TopologyGraphAvailable option and the 'Migrate Project to Constraint Manager Flow' feature, delivered by the ConstraintManager.ProjectMigrationWizard option (Advanced Settings), are now officially made Public with this release (both ON by default).
64592	Added support for the auto-creation of custom topologies for xNets that traverse discrete elements with more than 2 pins (e.g., a bank of resistors in a single part).

Draftsman

64359

When specifying the Units and Dual Units for a Draftsman-based document (as part of Document Options in the Properties panel), the entries in the corresponding drop-down menus are now presented in short form (e.g., 'cm' instead of 'Centimeters').

Wire Bonding

64122	Where a diff pair was being routed to a die that uses bond wires, the bond wires were violating the applicable diff pair routing rule (for width).
64301	For a wire bonding component placed within a cavity on an internal layer, die pads and bond wires were not rendering correctly ('floating in air') when viewing the PCB in 3D.

Harness Design

64264	When configuring cavities, values for 'Strip Length' and 'Pull Off Length' can now be defined for rows where no cavity type has been specified.
64324	Parameters defined for cavity parts and associated parts were not being propagated to the ActiveBOM document. (BC:24438)
64358	After changing the units for a HarDwf document at the document level (Document Options), the chosen units were reflected in the Length Units field for a selected wiring list, but the values were not being updated in the Length column.
64989	In a specific case, removing a particular harness covering from a harness design's layout drawing document resulted in the error "Index was out of range. Must be non-negative and less than the size of the collection..." being encountered.

Platform

63612	In some cases when working within an OutputJob document, an Access Violation (at address 000000014101CB39 in module "WorkspaceManager.DLL") would be encountered.
64262	In some cases when first starting Altium Designer, the vertical scrollbar for the Projects panel was not being drawn correctly and could not be accessed/used until after collapsing/expanding some entry in the panel itself.
64594	The 'Harness & Multi-board View Only Mode' feature, delivered by the System.ViewOnlyMode.Support option (Advanced Settings), is now officially made Public with this release (ON by default).
64595	After placing a TActionList component and drawing the required button on a script Form, attempting to access the ActionList Editor would result in an Access Violation (in module 'EditScript.DLL') being encountered.

Data Management

57403	After editing and releasing multiple components (from the Component editor in its Batch Component Editing mode), the data was not being refreshed automatically in the Explorer panel.
61385	In some cases for multi-channel designs using managed sheets, the Project Releaser would ignore applied Board Level Annotation, resulting in generation of a BOM with incorrect designators.
63784	When creating a comment for an alternative item in an ActiveBOM, the comment window would open partially off-screen and also appear with the header 'Row was removed'.
63851	After choosing a replacement alternate component for a component entry in a defined variant, the parameters were not being directly updated to those of that newly-chosen replacement. (BC:24598)
64072	In the Explorer panel, the 'Part requests' folder is now hidden if access to managed process workflows functionality is available.
64114	With multiple users working on a project in an Altium On-Prem Enterprise Server under SVN control, after one user migrates the project to the Server's built-in Git repository, another user, using the 'Update from Server' control (and subsequent 'Update local project folder' option), would encounter the error "Failed to update local project".
64173	When defining a Harness Wiring model (for a Harness Wiring component), attempting to 'Add Supplier Link And Parameters to Component' from an SPN tile of a chosen part in the Manufacturer Part Search panel, would cause Altium Designer to freeze. (BC:24737)
64227	When creating a new item through the Explorer panel, the Create New Item dialog's Revision ID field would present the ID using the revision naming scheme manually chosen for the last created item of that type, instead of the correct ID based on the item's actual default naming scheme.
64363	When saving a new component to a connected Workspace (with the Component editor in its Single Component Editing mode), the release would fail if a release note was entered of more than 255 characters. (BC:24819)
64381	For a defined project template in a connected Workspace whose Item Naming for project release uses custom project and variant parameters, release of a new project created from that template would result in generated data sets (Source, Fabrication, Assembly, Custom) not obeying that defined naming. Several custom parameters were being replaced with built-in parameters or removed entirely.
64431	The 'Save to Server' command was not available on the context menu associated with the VCS status icon, for the project document entry in the Projects panel.
64659	In some cases, SiliconExpert data in an Excel BOM exported from a Project's ActiveBOM, was not the same as the original data in the ActiveBOM itself.
64765	In some cases and for a very large project with a considerable number of documents, it would take a very long time to update the VCS status of the project.
64961	Placing a managed schematic sheet onto a schematic in a Workspace project and saving the project to the Workspace would result in incorrect operation of VCS statuses in the Projects panel, with the status for some documents stuck at 'refreshing'.

Import/Export

63627	When importing a specific xDX Designer design, a multi-part component was incorrectly being imported as separate parts.
63664	Added the ability to quickly toggle the inclusion state of multiple selected layers on the 'Current User Layer Mappings' page, when importing a Mentor Xpedition design.
64160	When importing an xDX Designer design, bus entries were being imported incorrectly on the generated schematic document(s).
64497	When attempting to export a rigid-flex design to STEP 3D or PARASOLID format and the design included routing tool path primitives, export would fail if, in the Export Options dialog, the 'Export Folded Board - Rate' slider was set to anything other than 0%. (BC:24858)
64531	Enhanced the progress indicator to better reflect the actual progress when importing a Mentor Xpedition design.
64586	Disabled unnecessary processing to significantly improve performance when importing a Mentor Xpedition design.

Power Analyzer by Keysight

64355	Surface layers were incorrectly being included into the internal layer max. current density simulation, causing the specified limit to be exceeded and the analysis to therefore fail.
64485	It was not possible to see all Pin Loads in the Load Properties dialog, as there was no ability to scale the dialog or scroll the listing.
64552	If more than 32 loads were configured for a single source, the error "Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Sequence contains no elements" would be encountered.
64553	When viewing the details for any network in an analysis report, the value presented for the 'Power Consumption for This Network' field was always displayed as "0 Watts", instead of the actual power consumption.
64554	When viewing an analysis report, the value for 'Max Via Current Density' (in the Global Settings section) and 'Max Current Density' (in the Failed Via Summary) was always displayed as "0 A/mm^2", instead of the value defined in the configuration.
64555	When configuring the load properties for a load component, Altium Designer would freeze if the Total Load Current was set lower than the Pin Load Current.
64709	If a layer was renamed for a board in the Layer Stack Manager, an error would be encountered when next attempting to open the design's associated Power Analyzer Keysight document (<ProjectName>.pdnaK).

Version 25.3.3 HotFix

Build: 18 Date: 17 February 2025

Schematic

59658	In some cases, junctions would disappear from a schematic. (BC:22687)
62926	A junction would disappear when moving a component across to the other side of that junction.
63185	In some cases when moving a component, the feature to show a visual indication of auto-junction connectivity would falsely display a tick when a short would be created, instead of an error. Note that the feature will now work exactly the same as it did in the past and known issues will be resolved in a future update. (BC:19438)
63718	It was no longer possible to reference a local folder of documents using the HelpURL parameter.
63722	After toggling the 'Fitted / Not Fitted' state of a component on the compiled tab of a schematic sheet, the project was not being marked as 'modified'. (BC:24535)
63843	In some cases with a compiled tab active on a schematic and switching to the PCB, selecting a component and then switching the active variant would result in the properties becoming empty.
63972	In some cases when opening a schematic document residing along a directory path ending with the '.' character, the error "System.AggregateException: One or more errors occurred. (Error reading the C:\Altium\git\ExamplePath\. directory..." would be encountered.

PCB

60875	For a specific design exported to Ansys EDB (direct or using Ansys CoDesigner), the component pin assignment for 3 chokes in the design were incorrect when viewed in Ansys Electronics Desktop.
62769	Export of board data to ODB++ v8.1 format now includes components that have been placed on a mid layer. (I:24432)
63926	For a specific design, attempting to export the PCB to Ansys EDB format resulted in the error "Cannot create component".
63960	After configuring a keyboard shortcut to access the Selection Filter, using that shortcut would open the filter in an area where most of its controls could not be seen/accessed.
64014	Added support for generating and placing QR and Data Matrix codes into a PCB design. (I:895)
64017	The 'User-defined Footprint Parameters' feature, delivered by the PCB.FootprintParameters option (Advanced Settings), is now officially made Public with this release (ON by default).
64154	When using the 'PadIsPlated' query language keyword (without Boolean qualifier) in an expression in the PCB Filter panel, objects other than plated thru-hole pads were also returned. (BC:24473)
64191	The 'Improved ODB++ Support' functionality, delivered by the ODB.Improvement option (Advanced Settings), is now officially made Public with this release (ON by default).
64390	For a design reuse block that includes a component with a custom-shaped pad connected to a net, after placing the reuse block on a schematic and pushing changes through to the PCB, attempting to drag the component into position would result in an Access Violation (at address 0000000194A9C17F in module 'ADVPCB.DLL') being encountered. (BC:24784)

PCB CoDesign

63963	It is now possible to select individual, multiple or all modification entries within any comparison category on the PCB CoDesign panel.
64104	In a specific case, changing one rule in the Physical view of the Constraint Manager resulted in more than 70K rule changes in the PCB CoDesign panel, making it impossible to keep working with Altium Designer due to the lengthy processing time of so many changes.
64113	In a specific case, detected changes to via types in the Layer Stack Manager were not being merged correctly, resulting in repeated changes being flagged in the PCB CoDesign panel.

Constraint Manager

61930	Polygonal-shaped rooms were being reset to become rectangular in shape after saving the Constraint Manager when accessed from the PCB (irrespective of whether changes were made to a room's definition or not). (BC:24592, BC:24641)
62928	After assigning a constraint set to a net class or diff pair class (in the Physical or Electrical views) and saving-closing-reopening, that assignment was not being saved.
62999	Clicking the 'New Clearance Rule' and 'New Connect Style' buttons (Polygon Pour Manager dialog) and the 'Create new clearance rule' button (Add Stitching to Net dialog) now create applicable advanced rules in the Constraint Manager. Note that the Constraint Manager is not automatically opened as part of this creation.
63075	When browsing the applicable binary rules between a net and a diff pair (members of respective classes), the Applicable Binary Rules window showed only the default Clearance rule and not correct query scoping for the Net Class and Diff Pair Class.
63121	Added horizontal auto-scrolling (where appropriate) in the bottom section of the Constraint Manager, when selecting multiple entities in, for example, rows of a table.
63242	Width constraints of nets and net classes are now validated in the top grid of the Physical view and highlighted using red text if values are found to be invalid.
63385	Defined Clearance rules in parameter set directives were being ignored by the Constraint Manager's 'Import from Directives' feature.
63656	After migration from the old rules system to the Constraint Manager, basic clearance rules (Net Class to Net Class, Net Class to All Differential Pairs, Net Class to All, Diff Pair Class to Diff Pair Class, Diff Pair Class to Net Class, Diff Pair Class to All Differential Pairs, Diff Pair Class to All) were incorrectly brought in as Advanced Rules, rather than into the Clearance Matrix.
63783	When using the context menu to copy and paste data between cells in the Constraint Manager's Physical view, the pasted data would be in XML format.
63814	After importing a constraint set, it was not available for use until after saving and reopening the Constraint Manager.
63958	It was not possible to create the same xNet once it had been removed.
64063	For a specific design, attempting to push changes from PCB to schematic through an ECO resulted in failure, with all nets showing "Net with name "<NetName>" doesn't exists".
64656	In some cases when working with the Constraint Manager, the error "System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection..." would be encountered.
64807	In some cases, changing between views or expanding sections within the scope area (e.g. a net class) would take a considerable length of time.

Wire Bonding

63868

In a specific case, moving a track to which a bond wire was connected caused the bond wire to break in two and its direction become reversed. (BC:24661)

Multi-board Design

63671

Where a multi-board schematic document featured multiple connectors and connections (of any type) between modules, there was very noticeable performance lag when attempting to move modules/connections.

Harness Design

58543	If a crimp component assigned to pins of a harness connector had no referenced symbol, the values for its defined parameters were not being displayed in the ActiveBOM. (BC:23079)
59685	The units defined for a harness manufacturing document (HarDwf) were not being applied to wires that were not part of a cable, in a placed wiring list and connection table.
61278	Added the ability to specify desired units for use with element lengths in the Wiring Diagram and Layout Drawing of a harness design. Supported units are: mm, cm, m, in, and ft, and can be specified at both the preferences (on a new 'Harness Design - General' page) and document level. In addition, and also part of the same new preferences page, you now have the ability to specify the 'Default Blank Sheet Size', used when creating a new wiring diagram or layout drawing document. (BC:23900, I:20186, I:23688)
61557	Standardized the list of units for use in a harness manufacturing document (HarDwf). Supported units are: mm, cm, m, in, ft, and mils. In addition, Length Units can be specified for a BOM table, connection table and wiring list (overriding units specified at the document level).
63938	In some cases when working with a harness design, the error "EOleException: Object reference not set to an instance of an object" would be encountered.
63955	Added the ability to display only 'no connect' objects in a connection table within a harness manufacturing document (HarDwf).
63974	A wire break associated to a white wire was white without a border color, making it invisible on a printed document.
64109	Where a Layout Drawing contained many harness coverings, opening the project's HarDwf document would take a long time. In addition, generation of PDF output through an OutJob would be very slow and the resulting file size considerably larger.

Data Management

62956	When the connected Workspace was changed during configuration of a CmpSync document, the subsequent error message incorrectly advised connection to the currently connected Workspace, instead of the previous Workspace.
63001	With the Component editor in 'Batch Component Editing' mode, you now have the ability to quickly set ranking for part choices automatically for any or all components, while keeping the order for any part choices already ranked.
63040	Improved login to an external Git repository. Now if you enter the incorrect credentials, Altium Designer will not attempt to login using those for your Altium On-Prem Enterprise Server. A login window will now appear with which to check and re-enter the correct credentials for your external repository.
63893	In some cases when browsing component part choices through the Components and Explorer panels, a "System.InvalidCastException: Unable to cast object..." error would be encountered.
63956	When comparing the ActiveBOM with a selected Managed BOM using the BOM CoDesign feature, if the alternates for a component are the same but only ordering of Part Choices was updated, such modifications are ignored and not listed in the Differences section.
63965	It was not possible to create a local project in a network folder location. An "Invalid project location" error would be encountered.
64057	When creating a new component in a connected Workspace with 'Standard' level of feature access, it was not possible to edit the Id for the component.
64209	When changing the lifecycle state of a component, the software now checks that its referenced models are in an applicable state to do so.
64303	In a specific case, attempting to open a design's ActiveBOM document would result in the error "Arithmetic operation resulted in an overflow..." being encountered.
64892	Returned the ability to Commit and Release projects that use SVN for version control in a connected Enterprise Server, where that Server still supports internal SVN repositories.

Import/Export

62273	When importing a specific Allegro design, width-related rules were being imported with incorrect values.
63364	When importing a specific Allegro design, an object of type 'mechanical component' was not being imported on the generated PCB document.

Power Analyzer by Keysight

63959	In some cases, vias were being reported as "not being able to withstand the current loads", even though the load current was below the configured maximum and no violations were present when using the 'Show on PCB' feature.
64006	When attempting to analyze all nets for a specific design, and with the 'Skip Ground' option disabled, the error "Failed! Something went wrong please try again" would be encountered.

SI Analyzer by Keysight

63680	When setting the 'Up to Frequency' value for Insertion Losses, it was possible to enter a value beyond the 20 GHz limit (not ultimately used), since the field was not validated against this limit.
64484	For a specific design, when attempting to analyze nets with overlapped pads, the error "An item with the same key has already been added. Key: SIAnalyzer.DataModel.Objects.NetPadItemDataModel" would be encountered.

Version 25.2.1

Build: 25 Date: 14 January 2025

Schematic

61772	For a multi-part component having primitives defined in only one sub-part, it was still (incorrectly) possible to switch sub-parts using the 'Increment Part Number' command, or change display mode through the SCH List panel.
63647	After using the Properties panel's Smart Edit Batch Replace feature for multiple selected strings on a schematic, clicking away from the selected items would incorrectly replace them all with the string of the first item in the selection (the string displayed in the Properties panel after the batch replace). (BC:24501)
63692	Improved speed of selecting multiple objects on a schematic document.
63863	During sequential placement of text strings on a schematic, the value of the Text field was not being selected in the Properties panel after pressing the Tab key.

PCB

61438	Added support for generating a list of nets and copper primitives that are intentionally allowed to short ('Net-Ties') when generating ODB++ V8.1 output
62767	Improved speed of opening large PCBs containing a very large number of regions.
63182	In some cases, the 'Unrouted (Manhattan)' parameter value for a net (PCB panel) would display as '0', even though an Un-routed Net violation for that net existed.
63188	In some cases when applying teardrops, the straight Line style would be applied instead of the chosen Curved style. (BC:24557)
63525	The 'Dynamic Phase Matching for DiffPairs' feature, delivered by the PCB.Rules.DiffpairPhaseMatching option (Advanced Settings), is now officially made Public with this release (ON by default).
63644	For some designs and with the PCB.Wirebonding option enabled (Advanced Settings), there was a negative impact on performance when switching between 2D and 3D views of the board, and with 3D Body visibility disabled in 2D.
63709	Improved selection speed for nets with via shielding and via stitching, especially on larger designs.
63745	In some cases, the bounding box for a selected component was not being displayed correctly if its footprint contained custom shaped pads whose shape had been edited.
63773	In the PCB Rules and Constraints Editor dialog, if a Matched Lengths rule's scope targeted an xSignal class, the Test Queries feature would always return '0' matching items. (BC:24434)
63774	Further improved PCB loading times, especially on larger designs, through internal optimization of pad registration.
63852	The Interactive Router would ignore cavities, allowing a trace to be placed despite the presence of a Clearance Boundary.
63874	The 'Auto-shrinking During Interactive Routing' feature, delivered by the PCB.Routing.EnableAutoShrinking option (Advanced Settings), is now officially made Public with this release (ON by default).
63881	The 'Routing Neck-Down Rule' feature, delivered by the PCB.Rules.RoutingNeckdown option (Advanced Settings), is now officially made Public with this release (ON by default).
64050	It was not possible to drag tracks close to desired objects (in HugNPush Obstacles mode). Dragging/sliding would lag or stop altogether.
64099	In some cases when routing between two vias, an Access Violation (in module 'RouterEntry.dll') would be encountered.
64124	In some cases when trying to open a PCB document (any PCB document), the error "E3DError: E_INVALIDARG" would be encountered. (BC:24742)
64185	In some cases while rerouting an incomplete connection, an Access Violation (in module 'RouterEntry.dll') would be encountered.

PCB CoDesign

60872	The 'ChannelOffset' property is now ignored when listing the detected conflicts for components.
63625	Conflicts on mechanical layers were incorrectly being presented in the PCB CoDesign panel as part of the 'Copper' category.
63628	For detected copper changes (Arc, Connection, Pad, Track, etc), the associated net name is now presented in the PCB CoDesign panel. In addition and for a connection, all layers on which that connection is represented are also now displayed.
63811	The 'RulePriority' property is now ignored when listing the detected conflicts for rules.
63847	Improved usability of the PCB CoDesign panel. Expanding and collapsing a category now keeps consistent presentation of conflict information and without displaying double scroll bars.
63858	Improved performance in comparison of connections, considerably reducing the overall time to perform a board comparison.

Constraint Manager

62483	From the PCB, after creating new Clearance rules (in the Clearance Matrix or Physical view for example), those rules would not appear in the All Rules view until after closing and re-accessing the Constraint Manager.
62986	After pushing 'Routing Neck-Down' constraints through to the PCB for a specific design, accessing the Constraint Manager's Physical view and changing the units to 'mm', the values for the Routing Neck-Down entries were still presented in 'mil' until saving and reopening.
63168	Added the ability to add a comment to a constraint/rule, across any of the views in the Constraint Manager.
63193	After choosing the Custom routing topology type, xSignals are now automatically created for simple xNets (those with one source, one destination and one discrete component between each pair of nets).
63226	After migrating from the old rules system to the Constraint Manager, the value of the 'Direction From Pad' constraint, for the default Fanout_BGA rule, was incorrect.
63538	Custom scopes defined and assigned to advanced rules in the All Rules view (when accessed from the PCB) were becoming unassigned after saving, closing and reopening the constraints and PCB.
63610	In some cases when adding a scope within the Clearances view, the error "System.Collections.Generic.KeyNotFoundException: The given key "ConstraintsManager.Module.DataModels.Scopes.ScopeData" was not present in the dictionary" would be encountered.
63655	Added the ability to remove multiple selected classes, xNets and differential pairs when working within the Physical and Electrical views.
63688	For a parameter set directive attached to a single wire, added the ability to display associated data from the Constraint Manager (net/diff pair class name and rule settings) near to that directive on the schematic sheet.
63732	Added the ability to delete multiple advanced rules from the All Rules view (when accessed from the PCB). Delete one or more selected advanced rules or all advanced rules of a particular type.
63735	Generation of xNets now supports serial components with more than two pins. The following serial components are supported: Single/Dual-inline component with an even number of pins; component with an odd number of pins.
64094	After importing a net class from a parameter set directive and then deleting that class from the Constraint Manager, the class would be added again on a subsequent refresh, with no way to delete it from the parameter set itself.
64125	After enabling the Creepage option (with a value) for an entry in the Clearances Matrix, copying and pasting any further cell values in the matrix would not be saved.
64136	After importing a parameter set directive, attached to a wire (net) and with a defined rule, moving that directive between wires (nets) would result in the rule becoming replicated within that directive. (BC:24143)
64137	For a parameter set directive including defined Net Classes, that is attached to a blanket, after syncing/importing with/to the Constraint Manager, it is now possible to toggle the display of Net Class directive information in the design space.

Draftsman

57464	When accessing the properties of a particular text object in a specific Draftsman document, the error "System.NullReferenceException: Object reference not set to an instance of an object" would be encountered.
63657	For a selected Diametral or Radial dimension on a PCBDwf, enabling the 'Override Value With' option and adding a value (in the Properties panel) would change the text value of the dimension in the design space, but its graphical display would remain unchanged.

Wire Bonding

62068	Added support for using the 'IsBondWireConnected' and 'IsBondFinger' query keywords when constructing query expressions to use in the filtering of objects in a PCB/PcbLib.
63687	Enhanced the binding of a die pad to an overlapping 3D body placed on the Die layer (referred to as a 'Die Body'). A die pad will now be linked to this overlapping die body, inheriting its height. Any geometric modifications to the die pad or die body (location, size, etc) will update the link, keeping the height of the die pad in-sync with its linked die body.

Harness Design

55163	In a Layout Drawing, after deleting a bundle with a covering and then using the Undo feature, the bundle would be restored but the covering would not be displayed in the design space (just its designator and comment).
61166	In some cases, the names of wires and cables in a BOM table (in a HarDwf document) were being reset if the ActiveBOM document was closed during the import of changes from the Layout Drawing.
63104	In some cases when adjusting a wire/bundle coming out of a main bundle on a Layout Drawing, any covering associated with the main bundle would disappear.
63329	In the Wiring Diagram, where a selected harness component had an alternate display mode defined, the Cavities tab (in the Properties panel) would present duplicated pin entries. (BC:24584)
63613	In some cases when choosing an associated part to use for the Physical Model for a selected connection point in a layout drawing, the error "System.InvalidOperationException: Sequence contains no elements" would be encountered.

Platform

63623

Changed the name of the dialog that appears when trying to use on-demand services and you are currently disconnected from Altium. Now titled 'On-demand Services Disabled', the information text has been made clearer, with a link provided to the System - Account Management page of Preferences.

63751

The ability to enable the use of self-signed certificates, delivered by the System.AllowSelfSignedCertificates option (Advanced Settings), is now officially made Public with this release (OFF by default). If enabled, it is advised to verify with your IT department. When using an Altium On-Prem Enterprise Server, it is recommended to generate your own certificate (using your standard/preferable tools) and then configure this certificate in IIS. For more information, see Configuring a Certificate.

Data Management

63482	In some cases when working with comments in an ActiveBOM, the error "System.NullReferenceException: Object reference not set to an instance of an object" would be encountered.
63495	Data shown in the Flat view for an Output Job's BOM output, with an alternatives group for a component defined, was not correct and did not match with the data in the same view mode in the ActiveBOM. (BC:24183)
63573	After deleting a Workspace component (through the Explorer panel), the 'Deleting...' pop-up window would not close after confirmation that the deletion was successful. (BC:24693)
63693	After releasing a specific and large PCB design multiple times using the Project Releaser, a memory leak would occur. (BC:23712)
63777	Enhanced the Manufacturer Part Search panel with more detailed information about a part's models, including whether they are considered 'Generic' or 'ECAD Ready'. In the latter case, such models have been 'qualified' by the manufacturer as being ready for use in CAD designs, with qualification the result of following a dedicated validation flow, in combination with adherence to a specific manufacturer datasheet, IPC standard and applicable revision of the publicly available 'CAD Model Style Guide'. This same information is made available in the Use Component Data dialog, when saving a part to a connected Workspace. For parts with Generic models, you have the ability to vote to get qualified models made/added.
63820	In a specific case after momentarily losing internet connection, the error "SearchTemplateService not found for current vault" was encountered in a 'looping' fashion, essentially freezing the software.
63828	In a specific case, attempting to generate PCB prints from an Output Job file, to a physical printing device configured as part of a Hard Copy Print Job, resulted in a hard crash (with no message) of Altium Designer.
63834	When importing components from a specific database library into a connected Workspace using the Library Importer, part choices were not being migrated correctly, instead becoming mixed up between components.
63837	When configuring a variant for a design, any specified alternate part for a component was missing the base (non-varied) footprint for that component when viewing that variant in 3D, and generating manufacturing (fabrication and assembly) outputs for it, when the option 'Do not overwrite PCB footprint' was enabled.
63890	In specific versions of Altium Designer (24.8.2, 24.9.1, 24.10.1) and when using a specific Excel BOM template uploaded to a connected Workspace, it was not possible to generate BOM output using the file format "Generic XLS". The error "Failed to open Excel Template – The template file may be corrupted or in unsupported format" would be encountered.
64080	Search filter range fields ('From:' and 'To:') in the Manufacturer Part Search panel, and some search filters in the Components panel, were presenting in imperial (mil) but not metric (mm).
64086	In some cases, trying to place a component from a newly-created DbLib would result in the error "DocView is not available" being encountered. In other cases, this same error would appear when trying to add a new DbLink file to a project. (BC:24775)

Import/Export

61990	Added support for custom ports, custom power ports and custom off-sheet connectors, when importing an xDX Designer design.
62256	When importing a specific Allegro design, spacing/clearance rules were being imported with incorrect values in the clearance matrices of the applicable design rules for the generated PCB document.

Power Analyzer by Keysight

63700

After making a change to a component's designator in the design, the Power Analyzer Keysight document (<ProjectName>.pdnaK) would become corrupted, leading to the error "VemEngine failed" being encountered when attempting to perform an analysis.

SI Analyzer by Keysight

64082	When attempting to analyze a specific design, the error "An item with the same key has already been added. Key: SIAnalyzer.DataModel.Objects.NetPadItemDataModel" would be encountered.
64115	For a specific design, performing an analysis would never run to completion.

Other

60387

In some cases, the error "EAccessViolation: Access violation at address 0000001400A60D2D in module "X2.EXE"" would be encountered.

Version 25.1.2

Build: 22 Date: 12 December 2024

Schematic

62598	For a design with alternate parts specified in variants, using the 'Update Parameters From Database' command would lead to an Access Violation (at address 00000001420CB80F in module ‘WorkspaceManager.DLL') being encountered in the ECO dialog. (BC:23993, BC:24337)
62914	The arithmetic functions CEIL, FLOOR, FRAC, INT, MAX, MIN, POWER, SIGN, SQR, SQRT, TRUNC, and ZERO were not being resolved when used within a placed special string on a schematic.
62968	In some cases, the error "EOleException: The method or operation is not implemented" would be encountered.
63190	When placing a reuse block with a blanket, as a sheet symbol, the blanket was moved 50mils to one side.
63198	When using the new Variant Manager (UI.ModernVariantsManager ON), the error "Value cannot be null. (Parameter 'key')" would be encountered if a component parameter was named '*'.
63371	Switching between schematic documents was sending too many requests to the connected Workspace, impacting performance.

PCB

59813	For a specific and large design, selecting various pads throughout the board would take a long time, effectively 'freezing' Altium Designer.
61919	In some cases when using the Automatic Length Tuning feature with multiple selected traces, performance was noticeably slow, with tuning taking in excess of a minute to complete.
62460	With a specific PCB open and the PCB panel set to its 'Hole Size Editor' mode, switching to and changing a parameter in the Layer Stack Manager, then coming back to the PCB again, would result in an Access Violation being encountered.
62893	As part of automatic loop removal when using the Interactive Router, connections to polygon pours are no longer severed.
62940	Improved support for exporting a panelized PCB (Embedded Board Array) to Parasolid format. A Route Tool Path is now cut through all board layers in the exported file, and cavities and board cutouts from a source board are now also taken into account on the panelized PCB.
63110	In a specific case when making changes to the layer stack for a board and then switching back to the PCB and saving, an Access Violation (in module ADVPCB.DLL) would be encountered.
63262	The feature to improve performance of PCB loading by using regions triangulation cache, delivered by the PCB.Performance.UseRegionTriangulationCache option (Advanced Settings), is now officially made Public with this release (ON by default).

63517	The 'Enhanced Return Path Rule' feature, delivered by the PCB.Rules.CheckReturnPathVia option (Advanced Settings), is now officially made Public with this release (ON by default).
63543	For a specific design, switching between 2D and 3D viewing modes would take several minutes.
63583	The 'Enhanced Automatic Loop Removal' feature, delivered by the Legacy.PCB.Routing.LoopRemoval option (Advanced Settings), remains in Open Beta (OFF by default) with this release, but now applies to all routing modes.
63601	For a specific PCB design containing differential pairs, attempting to export into Ansys EDB format would result in the error "Object reference not set to an instance of an object" being encountered.
63661	For some outlines composed of lines and arcs, the "Create Region From Selected Primitives" feature did not work, and there was no message to offer automated resolution. (BC:24031)
63672	Updated terminology in the 'Auto Tuning Process' dialog to better reflect control actions. Pattern -> 'Tuning Goal', Accordion -> 'Min/Max/Group Matching', Sawtooth -> 'Within Pair Matching'.
63865	When generating a PDF from a panelized board, custom pad shapes were incorrectly being shown printed with an offset and rotated. (BC:24230)

PCB CoDesign

63255	When viewing changes to components in the PCB CoDesign panel, components are now sorted by designator rather than alphabetically.
63340	Improved performance when comparing and merging changes made to very large designs.
63487	The 'PourIndex' property is now ignored when listing the detected conflicts for polygon pours.
63502	For a specific design, unexpected conflicts were being presented after running a comparison.
63563	In a specific case after running a comparison, attempting to resolve conflicts using the Remote design (latest commit in the connected Workspace) would result in an error being encountered upon merging.
63650	When performing a Compare and Merge for a specific design, the primitives within one component were being duplicated.
63654	When performing a Compare and Merge for a specific design and repouring all polygon pours, some polygons would not repour, while others would partially disappear from a particular layer.

Constraint Manager

61226	Additional layers of clearances defined for All Nets in the Clearances view, were not being correctly transferred to the Clearance entry for All Nets in the Physical view.
62309	When creating a new class from expanded xNets (with both xNets and nets selected), the class contained duplicate entries for those xNets and nets.
62745	When importing a constraint set into which Clearance rules were exported, those Clearance rules were missing in the 'Constraint Sets to Import' dialog, and therefore not imported.
62961	After removing all rule values for an entity with a constraint set assigned (Physical/Electrical view), the name of the set itself was not being removed.
63125	When attempting to access the Constraint Manager from a specific PCB, the error "An item with the same key has already been added" would be encountered.
63143	With a Routing Via Style advanced rule selected (All Rules view when accessed from PCB), choosing 'Template preferred' in the lower section did not display a table of via templates from which to enable.
63195	When creating a new Workspace project from a project template in which constraints have been defined (using the Constraint Manager), those constraints were not being presented until the newly-created project was closed and reopened.
63221	Export/import of constraints/constraint sets is now handled by a single Export/Import command respectively. In addition, when importing a constraint and constraint set with the same scope, the constraint set will be used.
63398	For rules added to a parameter set directive that are not presented in the Physical and Electrical views, those rules will automatically be created as Advanced Rules, upon completion of either import of directives or migration from the older rule management system, and subsequent ECO from the schematic through to the PCB.

Draftsman

62618	When attempting to open a specific PCB manufacturing file (PCBDwf), the document would not open and was consuming 80% RAM.
63501	When defining a custom sheet size for a Draftsman document, the maximum Width and Height that can be entered is now 20000 mm.

Wire Bonding

61402	When using the 'Align Bond Finger with Bond Wire' feature, the bond finger pads are now correctly oriented, with the longer side of a pad always kept in parallel with the bond wire.
63404	Improved the Find Similar Objects dialog in the context of bond wires, to now include 'Diameter', 'Die Bond Type', 'Length 3D', and 'Loop Height' object-specific parameters.

3D-MID Design

63396

While routing on the substrate of a specific design, Altium Designer would suddenly freeze.

Multi-board Design

53686	When trying to open a specific multi-board schematic document, the error "Unable to load drawing document..." would be encountered.
63114	When selecting a harness object in a specific multi-board schematic document, the error "Unable to cast object of type..." would be encountered.

Harness Design

63099	When importing changes into a manufacturing document (HarDwf), the ECO process was not detecting any changes to the capitalization of parameters.
63120	Changed the color used for text in the 'Length Value' and 'Offset Length' columns (Bundle Objects section of the Properties panel, with a bundle selected in the Layout Drawing) to improve readability when an entire row/column is selected.
63609	In some cases when performing interactive actions on some object types in a Wiring Diagram/Layout Drawing (e.g., copying a wire), and where the Properties panel was active, but not visible, the error "System.ArgumentNullException: Value cannot be null. (Parameter "source")" would be encountered.

Platform

58194	In some cases when opening the Explorer panel, the error "EOleException: EndInit. Must call BeginInit before EndInit" would be encountered.
59094	In some cases, Altium Designer would freeze when working with Database Library (DbLib) and Database Link (DbLink) files. (BC:22438)
62639	Added an Advanced Settings option (System.UnifiedLogin) that when enabled, provides a single location for signing in to your Altium Account via an external browser, using direct email credentials, a linked Facebook or Google account, or through configured SSO.
62792	The option to use CefSharp v.126 for browser-related elements within Altium Designer, delivered by the System.UseCefSharp123 option (Advanced Settings), is now officially made Public with this release (ON by default).
62965	Altium Designer would terminate when trying to open/close a project and its documents if the third party application "Sticky Password" was also running.
63327	The ability to enable the use of self-signed certificates, delivered by the System.AllowSelfSignedCertificates option (Advanced Settings), remains in Open Beta but is now OFF by default with this release. If enabled, it is advised to verify with your IT department. When using an Altium On-Prem Enterprise Server, it is recommended to generate your own certificate (using your standard/preferable tools) and then configure this certificate in IIS. For more information, see Configuring a Certificate.
63381	The option "Unified Sign In" is now enabled by default in the Advanced Settings window of the Altium Designer installer. When enabled, it replaces login to your Altium Account by UserName\Password with unified login via an external browser.
63749	When running a specific script to generate output files, there was an error generating schematic prints in a PDF file.

Data Management

54731	In some cases when grouping and sorting results in the Components panel, the error "System.AggregateException: One or more errors occurred..." would be encountered.
59781	After saving changes to a specific design to a connected Altium 365 Workspace, the Web Viewer was not updating to reflect those changes.
60191	'Shared with Me' projects did not receive real-time updates to comments and replies in AD, where changes were being made through the Workspace's browser interface or by another user.
62984	Hidden pins were not being taken into consideration as part of the 'Number of Pads exceeds Number of Pins' validation check for a Workspace component. (BC:24190)
63003	When editing a Workspace component and copying a symbol or footprint model, the name of the copied model is now given the prefix 'Copy of'. (BC:24196)
63004	When editing a Workspace component and copying a footprint model, it is now possible to choose whether to keep the original model and the copy or to replace the original with the copy. (BC:24196)

Harness Design

61319	Added the ability to override the calculated length for a wire on the Layout Drawing, either by manually defining the required absolute length, or by adding an offset to calculated data. If the design is synchronized with MCAD (using MCAD CoDesigner), length data is obtained on pulling the design from MCAD, with the ability to manually override if needed.
62179	It was not possible to split a cable using splices on selected wires of that cable.
62340	Beyond initial import, component orientation in the layout drawing was incorrectly still following that in the wiring diagram, on subsequent imports of the latter.
62342	When connecting two wires of differing gauge, an 'Unnecessary Splice' violation would incorrectly arise.
62818	When adding an associated part to a connection point and changing the latter's designator, the BOM was not correctly displaying this designator, leading to duplicate entries.

62963	For a project stored in a connected Workspace, the 'database' part of its icon has been removed from all relevant places in the UI (e.g., Projects panel and Open Project dialog).
63078	When opening the history for a project from within the Explorer panel (project not open in Projects panel), using the 'Revert To' feature would cause a hard crash.

Requirements Management

62874

Added ability, while placing a requirement within Altium Designer, to click on its ID to open that project requirement within Altium 365.

Import/Export

62070	When importing a specific Xpedition library, an 'assertion failure' error would be encountered, with the entire import taking a long time and consuming >90% of computer memory.

62458	Online DRC is now suppressed when merging, making the merge process faster.
62478	Changing the origin of the board would cause component coordinates to change, leading to conflicts when running a comparison.
62536	Added the ability to merge object properties, where there are no conflicts in value, significantly reducing the number of object conflicts.

Constraint Manager

61707	It was possible to add a net class with the same name as a differential pair class (e.g. in the Physical view), leading to an error being encountered when trying to add the second class to the Clearances matrix.

61376	In some cases after copying/pasting an error-free union of precisely placed components elsewhere in a design, some of the replicated groups of components would produce component clearance violations.
61955	It is now possible to place components close enough that their courtyard outlines exactly overlap. To disable clearance checking (when a design requires overlapping components) enter a negative value for the Minimum Horizontal Clearance in the applicable Component Clearance rule. (BC:3247, BC:22953, I:21187)
62115	For a selected Workspace component, it is now possible to select and copy its footprint name, from the Footprint Name field in the Properties panel.

61057	After updating a Workspace component in the Layout Drawing to its latest revision, its physical models would have their rotation reset to 0 if they had been previously rotated using the Spacebar.
61827	In a specific case, opening a HarDwf document that included a Wiring Diagram View or Layout Drawing View containing a text frame with an empty line, would result in the error "Object reference not set to an instance of an object".

Platform

57606	In some cases when accessing the Columns Editor for a TListView object in a scripting Form, an Access Violation (in module 'EditScript.DLL') would be encountered. (BC:21877)
61421	Updated text throughout the License Management UI to make it clear that subscription renewals are no longer available for perpetual licenses. After expiration, a perpetual license can still be used, but you won't have access to later updates for Altium Designer beyond that point (no new features/functionality), nor will you have access to cloud capabilities delivered through, and by, the Altium 365 platform.
62546	With the advanced settings option 'System.UseCefSharp123' ON, a crash would be encountered when opening a second instance of Altium Designer.

61353	When using Board Level Annotation, a document channel set to not use 'Designator Index Control' had incorrect designator indexing applied.
61429	Parameter update settings defined in the Library Update Settings dialog (Item Manager advanced update options) were not being retained.

PCB

56711	The Interactive Routing tools now support the ability to configure and apply "Trace Centering", allowing for traces to be centered between obstacles as you route.
57986	Interactive Routing tools now support true "Zero Mitering". If the Miter Ratio = 0, no miter will be created (previously, a short miter fully covered by adjacent traces was created).
59164	Added a new 'Routing Neck-Down' rule enabling you to define the maximum allowed length of a Neck-Down trace when its width is less than the Preferred Width. (I:11512)
59341	Added the ability to create a single layer PCB, with corresponding support in the PCB editor, Layer Stack Manager and generated outputs. (I:10797)
59835	Added a round 'Donut' shape to the listing of predefined pad shapes available when defining the padstack. (I:18588)
60366	An 'Auto-Shrinking' option has been added to the Interactive Router (single-ended routing), allowing a trace to be narrowed to the applicable width in tight places as you route.
60618	After exporting a PCB to EDB format, opening the file in Ansys revealed arcs not to be very smooth in places.
61062	After importing a DXF file, attempting to select and convert all individual shapes into a single region (Tools » Convert » Create Region from Selected Primitives) would only convert one of them.
61083	When selecting holes through the PCB panel's Hole Size Editor, only one via from each selected group (in the Unique Holes section) was getting selected within the main design area. (BC:23361)
61208	For a specific design, Altium Designer would hang when running a DRC if the advanced option PCB.Rules.Width.CopperLoopsCalculation was enabled and when the 'Check Min/Max Width for Physically Connected' option was also enabled in a Width rule. (BC:23283)
61418	When using the Constraint Manager with a project, specific clearances defined for net classes were not being observed when interactively routing and dragging. (BC:23164)
61448	Different clearances were being applied between a component's SMD pads and a polygon pour if the SMD pads had their 'Plated' property incorrectly set to ON. (BC:20733)
61610	Removed the '[nOhm]' entry from the label for the Copper Resistance field (when configuring Layer Stack properties through the Properties panel). Value entered is in nΩ.
61729	When routing a differential pair between existing routed parts of the pair, it was not possible to end the route at any point on existing Diffpair track.
61748	The Interactive Router would ignore a closed region as being an obstacle, resulting in a dragged track (within the region) suddenly being pushed outside of it.
61916	In some cases when using the Automatic Length Tuning feature (with default parameters), the resulting tuning patterns would create short-circuit violations.
62025	For a Workspace component referencing a PCB Footprint with an empty Name, using the Update From PCB Libraries feature would show this as a failed match item and "Component Is Not Properly Linked And Synchronized. No Comparison Data Available."
62030	The feature to control whether or not drill symbols are automatically updated (live update) is now officially made Public with this release (OFF by default).
62232	When viewing a board in 3D, clicking to select a component would select the 3D body instead, presenting information for the latter in the Properties panel instead of that of the component.
62345	While interactively routing, it was not possible to change the Via Diameter or Via Hole Size through the Properties panel.

PCB CoDesign

61267

Added support for 'Copper Resistance' and 'Via Plating Thickness' parameters (defined as part of Layer Stack Manager properties).

Constraint Manager

57002	In some cases after successfully passing changes from the schematic to the PCB through ECO, accessing the ECO again would list the same 'Change Rules' actions.
59635	Values set (on the PCB side) for Min Width/Preferred Width/Max Width for inner layers were being reset to defaults, after executing an ECO to update the PCB with changes made on the schematic. (BC:23198)
60732	Added the ability to export and import constraints between designs.
60823	Some of the icons used within the UI were inconsistent.
61024	When accessing the Constraint Manager from the schematic, it is now possible to choose and configure specific width constraints (per layer) for any PCB document in the same design project, and independently across layer stacks defined for that chosen board. This applies when configuring Width and Differential Pairs Routing constraints (from the Physical view). (BC:23866)
61082	After saving a selected cell as a constraint set from the Clearances view (accessed from PCB), the constraint set was not being displayed after saving changes and then closing/reopening the Constraint Manager.
61195	In a specific case, changing a value for a cell in the Clearances view (accessed from PCB) and then clicking another cell, would result in the AV "The given key was not present" being encountered.
61200	The constraint UI for the Clearance rule when accessed from the All Rules tab has been corrected, now matching that seen from the main Clearances view.
61227	The command to access the Constraint Manager, from the Schematic side, has been moved up in the main Design menu to make it positionally similar to that on the PCB side.
61320	In some cases, changing the layer stack for a PCB and then accessing the (already open) Constraint Manager would result in the error "An item with the same key has already been added" being encountered.
61629	After changing the size of a room on a PCB and saving, making and saving any subsequent change in the Constraint Manager would result in the room being set back to its previous size.
61702	It is now possible to enable/disable advanced rules defined in the All Rules view (when the Constraint Manager is accessed from the PCB).
61791	By default, directives imported from read-only documents (device sheets, managed sheets) cannot be modified unless the 'Make Device Sheets in Projects Read-only' option is disabled (Data Management - Device Sheets page of Preferences).
61836	Added the ability to enable use of a chosen Impedance Profile, when configuring a Width or Differential Pairs Routing rule on the schematic side (through the Edit PCB Rule (From Schematic) dialog).

Draftsman

60961

In some cases after deleting merged cells in a placed table, the error "Index was outside the bounds of the array" would be encountered. The document could not be opened again if saved after this.

61576	Added the ability to select and drag multiple components on the substrate.
61580	The name of (and full path to) the 3D substrate file is now presented in the Properties panel.

Multi-board Design

60594	After swapping pin numbers of a mated part, the net name of the System Connector and Mated part were not matching, making it look like two different nets were getting shorted together.
61035	In some cases, importing changes from a child project into the multi-board schematic resulted in the repetitive error "The Reference Pin is in the net" being encountered.
61479	Changes to Module Net naming was not preserved in the Connection Manager, nor visible in the Properties panel, but was transferred to child projects through the ECO process.

Harness Design

60593	Added ability to specify 'Strip Length' and 'Pull Off Length' when defining a crimp-type cavity in the Wiring Diagram. These properties are included in the wiring list and connection table objects in a HarDwf document.
60765	Added support for splitting a cable by adding splices to selected wires of the cable.
61137	'No Connect' objects placed within a Wiring Diagram were displayed with the generic 'NC' entry in the HarDwf's Wiring List and Connection Table, instead of real designator naming.
61331	Added the ability to display the text value for a layout label in the BOM.
61684	Added support for using commenting and tasks features in a Harness Draftsman document (.HarDwf).

Platform

61372	In some cases when changing the main monitor display (and with Altium Designer open with a Draftsman document active), the error "UCEERR_RENDERTHREADFAILURE (Exception from HRESULT:0x88980406)" would be encountered. (BC:20761)
61422	The 'Open Any Existing Document' button would disappear from the Quick Access Bar when connected to a Workspace.
61704	It was not possible to enter a space character in the Project Name field when creating a new project.

Data Management

60805	'History & Version Control' right-click context menu (Projects panel) updated with minor terminology changes and comparison commands in context with the document under the cursor when accessed.
61213	When cloning a component with defined part choice(s) in the Component editor's Batch Editing mode, the part choice data was not being included.
61216	For an opened Workspace design, trying to make a schematic or integrated library when not connected to the Workspace would result in the error "Access denied! User login required for this service". (BC:23254)
61299	The 'Save Project as Template to Server' command has been removed from the File menu for a Scripting project, since it is not applicable to this type of project.
61527	In some cases, using the Window » Close All command right after connection to a Workspace, would result in the error "Unable to cast COM object of type "System.__ComObject"...".
61604	It was not possible to assign a default OutJob document through the Defaults tab of the Data Management - Templates page of Preferences. (BC:23553)
61608	Added a new violation type 'Number of Pads exceeds Number of Pins' as part of the validation checks that can be configured for a Workspace component. (I:17154)
61692	When defining a Components Synchronization Configuration document (*.CmpSync) for Database to Workspace component synchronization, you can now map a database parameter to the Workspace component's Item ID.
61693	In some cases and for some suppliers, ActiveBOM was not able to find supplier data for file-based components with linked supplier data. (BC:23454)
61694	When batch releasing changes to components (Batch Component Editing), all components were being disabled for release by default, if a part choice for at least one had been changed through the preview window.
61941	It was not possible to choose the native Git repository as the target, when making a local project available on a connected Altium On-Prem Enterprise Server.
61973	In some cases when working with the Components panel, the following error would be encountered "System.AggregateException: One or more errors occurred. ---> System.ServiceModel.FaultException: Access denied! User login required for this service".
62277	In some cases when generating a report of exported comments through an OutJob, the error "Object reference not set to an instance of an object" would be encountered.
62367	When creating a new component in a connected Workspace, switching to Batch Component Editing mode would see the defined target folder path truncated to a maximum of '2 child folders' below the 'Components' parent folder.

Import/Export

58148	When importing a specific xDX Designer design, the 'Symbol name' parameter was missing for all imported parts.
60290	When importing an Xpedition design/library, support has been added for round 'Donut' pads.
60990	When importing an xDX Designer design, active low net labels were being imported as active high (net label negation was not supported), causing different nets (with same name) to be incorrectly connected.
61337	When importing a specific Allegro design (brd + dcfx), clearance values for Fill-Fill, Poly-Poly and Region-Region were incorrect, when compared to the 'Shape To Shape' value defined in Allegro.
61338	When importing a specific Allegro design (and dcfx file), the imported Routing Width rule referred to the physical CSet name instead of the actual Net name.
61803	When importing a KiCad v.8 design, designators were not being imported correctly on the generated PCB, instead appearing as 'Unx', which broke component linking to the schematic-side components.

Circuit Simulation

60625

In some cases when opening a project and the Simulation Dashboard panel was active, the error "ValueFactory attempted to access the Value property of this instance" would be encountered.

Other

56818

Altium Designer would freeze when connected to an Altium On-Prem Enterprise Server and attempting to publish custom extensions using the Altium DXP Developer interface.

Version 24.7.2

Build: 38 Date: 23 July 2024

Schematic

59542	In some cases when using Smart Paste to paste an object in an array, the row spacing value would lead to incorrect placement of the object in relation to defined columns for the array. (BC:22584)
60079	Added the ability to choose a component as an alternate part in a variant, without changing the symbol on the schematic or adding a footprint to the PCB. (I:4369, I:18678)
60725	Improved single/multi-part symbol handling. If a multi-part component only has primitives defined in one sub-part, the designator suffix is now hidden. No longer possible to select a sub-part (or alternate display mode) when that sub-part / mode is empty (has no primitives).
61121	Added a new 'Port with no matching ports' violation type to the Error Reporting tab (Project options) for detecting, in a flat design, a port that has no corresponding/matching port across source schematics. (I:5885)
61122	There was a visual bug with Port names on compiled sheets (and generated PDF output) in multi-channel designs not being displayed correctly. The channel suffix was being used, rather than taking the higher level naming.
61124	For a project using a managed sheet and a defined variant with an alternate component, running Board Level Annotation loaded the alternate as an additional component each time.
61214	In some cases when adding an alternate part for a variant, the error "Illegal characters in path..." would be encountered.
61659	In some cases, Altium Designer would 'freeze' when moving objects on schematics in a large design, and where the Properties panel was open.

PCB

59354	When entering a value (without units) for a pad's Corner Radius, the default unit was being unexpectedly changed, so the expected value (in %) would instead be added as that value in mil. (BC:23124)
59993	Extended the Return Path rule, with ability to specify a 'Max Stitch Via Distance', with Batch DRC support to flag a violation if this distance is exceeded. (I:12747)
60682	Introduced a new implementation of automatic loop removal in the Interactive Router, improving behavior in the case of any angle routing and laying the foundation for future enhancements.
61026	The Gap value, for a Clearance rule shown in the Applicable Binary Rules dialog, did not match the value defined in the Constraint Manager.
61037	With PCB.Pad.CustomShape.CornerRadiusAbsolute enabled, the corner radius (%) defined in a PvLib created with a previous version of the software (<24.3), would be displayed as 0%.
61054	In a specific case and where multiple design documents were open in a tiled style, a hard crash would be encountered when dragging a trace on the design's PCB document.
61055	Added 'Copper Resistance' and 'Via Plating Thickness' parameters to Layer Stack Manager properties, for inclusion when exporting into Ansys EDB format. 'Via Plating Thickness' also supported by the Power Analyzer by Keysight tool.
61086	In some cases when adding teardrops, an irregular shape would be generated where a trace entered a pad at an angle. (I:21090)
61201	In a specific case, import of a DXF file into a new PCB resulted in several source arcs having different start and end angles.
61209	Polygons were not being poured with the specified distance defined by the applicable Creepage Distance rule, when multilayer pads (TH Pads) were part of the nets covered by that rule. (BC:18273)
61262	For a specific design utilizing Advanced Rigid-Flex and nested regions, Top copper pads in a specific location on the board were absent in the generated Gerber files.
61290	In some cases when performing single-sided length tuning for a trace, an Access Violation (in module "RouterEntry.dll") would be encountered.
61316	With advanced option PCB.RigidFlex.SubstackPlanning OFF, exporting a PCB into Ansys EDB format would result in the error "External component has thrown an exception" being encountered.
61333	Using the Properties panel, it was not possible to apply a manual paste expansion to multiple selected pads. (BC:23117)
61399	In some cases when exporting to DXF format, polygons and copper regions were exported unfilled. (I:3918, BC:14157)
61480	The 'Absolute Value for Pad Corner Radius/Chamfer' feature is now officially made Public with this release.
61494	The values for unrouted net lengths (when browsing nets in the PCB panel) were displayed as 'n\a' for power nets.
61515	In some cases when exporting to DWG format (with 'Export with polylines' option enabled), slot holes were either incorrectly shaped or had copper on them. In other cases, slot holes were incorrectly round and pads incorrectly located (when offset from hole locations). (BC:20855)
62015	Right-clicking did not always end an interactive command in the PCB editor (e.g. routing). Note that this fix essentially reverts the fix for issue #60489, made in Altium Designer 24.6.

PCB CoDesign

60984	Added a 'Leave Feedback' control to the PCB CoDesign panel, allowing you to quickly send feedback directly to Altium Developers, with suggestions/issues related just to the PCB CoDesign feature.
61066	The appearance of the '!!' icon in the Action Required dialog was incorrect when using the 'Altium Light Gray' theme.
61067	The banner that appears at the bottom of the PCB document when in the 'Document is Out Of Date' state had a 'close cross' that was barely visible when using the 'Altium Light Gray' theme.
62040	In some rare cases, the PCB CoDesign panel would not show any differences to be merged, leading to changes already saved by one user being overwritten by those made by another.
62069	In some cases, an invalid revision would be saved to the server when multiple users pushed their changes at the same time, with one user getting the Git Error "Request failed with status code: 500".

Constraint Manager

59755	When accessing rule information from within the PCB (e.g. applicable Unary/Binary rule or violations for an object) the Constraint Manager will open with the applicable rule cell highlighted.
60073	The 'All Differential Pairs' scope present in the 'Electrical - Diff Pairs' view was treated as the 'All' one underneath and, thus, was completely unrelated to the 'All Differential Pairs' one present in the 'Physical' view.
60100	Changes made solely within the Constraint Manager were not being detected as having modified the parent project, with no offer to 'Save to Server' presented in the Projects panel.
60243	Added the ability to export and import constraint sets.
60324	Advanced Rules, supported only in the PCB-side Constraint Manager, would be incorrectly suggested as missing on the Schematic side during the ECO process from the PCB.
60997	A value specified in the All Nets - Min Width field (Physical view) was not being inherited by the child nets (those not having had a custom value already defined for them).
60999	There was a synchronization issue between having made changes in the Constraint Manager and subsequent changes on a schematic, where the latter were not synced and the Refresh button was grayed out.
61025	Added support for a global 'Ignore Pad to Pad clearances within a footprint' option as part of the Constraint Manager's properties, for quick application to all defined clearance rules.
61107	When editing the width rule for an entity on the Physical tab, the bottom table now supports single-click to edit a cell's value, as well as multi-cell editing.

Draftsman

60782	Improved performance when working with a Draftsman document whose source PCB has a high number of 3D models.
61199	Improved dragging of views within a document. You can now move views around without experiencing any detrimental lag.
61294	In some cases when trying to add a comment to a Draftsman document, the error "An item with the same key has already been added. Key: PageId" would be encountered. (BC:23752)

3D-MID Design

60898

For a specific design, dragging an antenna footprint over the substrate led to an Access Violation.

Multi-board Design

60731

The graphical line type defined for a harness on a multi-board schematic was not being faithfully reflected when viewing that document through the connected Workspace's Web Viewer.

Harness Design

59913	It was not possible to set the length for a bundle to be greater than 5454 mm.
60166	Added the ability to control what cavity information appears in a placed Connection Table within a HarDwf document.
60585	Pasted copies of a harness covering were not visible on the Layout Drawing, yet were actually there and were reflected in the ActiveBOM document. (BC:21690)
61307	Added support for using commenting and tasks features in a Harness Design document (Wiring Diagram and Layout Drawing).

Platform

60568	In some cases when updating an installation of Altium Designer and the update fails, a rollback was not performed, leaving the software in an inconsistent state.
61030	Starting from this release, all 'SOLIDWORKS PCB Connector' extensions are no longer available, as well as the duplicate 'MCAD IDX Exchange (Mechanical CAD Collaboration)' extension.
61143	In some cases when updating Altium Designer, the Installer asked to "Please close Altium Designer to continue" even though the software was not running, preventing installation.

Data Management

60640	Parameters defined in a project template are now visible when choosing to use that template, when creating a new project through the Create Project dialog. (I:14283)
61068	Default sizing and appearance of the Edit Templates dialog (accessed from 'Data Management - Component Types' preferences page) was incorrect when using the 'Altium Light Gray' theme.
61144	Coloring used for filtering UI elements in the Components and Manufacturer Part Search panels, when using the 'Altium Light Gray' theme, were incorrect.
61211	In some cases, attempting to download a Reuse Block through the Explorer panel would lead to the error "Failed to download documents. Invalid item revision URL" being encountered.
61245	In some cases, the Comment/Name field for an alternate part in a defined variant was empty in the ActiveBOM document.
61261	When making and saving changes to a shared Workspace project, an error dialog "Git Error - Please connect to target server first" would appear, even though the Workspace was connected.
61313	The dialog that appears when another user starts editing a soft-locked document had a 'close cross' that was barely visible when using the 'Altium Light Gray' theme.
61330	The command to 'Clone' an existing project has been renamed 'Make a Copy' throughout the UI.
61347	For a specific Workspace and design therein, the 'Manufacturer 1' and 'Manufacturer Part Number 1' fields were empty for alternate parts in the ActiveBOM. (BC:22884)

Import/Export

58143	When importing an xDX Designer design, you can now define substitution parameters for component mapping (Footprint, Designator, Comment and Description fields). If the first parameter does not exist, the next will be used, in sequence.
61021	When importing a specific OrCAD design, some components were being imported with their designators reset (U?) on the generated schematic documents.

Power Analyzer by Keysight

55264

Added support for the 'Via Plating Thickness' parameter, defined for the PCB as part of Layer Stack Manager properties.

Other

61071

For a specific Script project, attempting to change the properties for a selected control on the Form, using the Object Inspector panel, resulted in an Access Violation (in the EditScript module).
