Version 23.3.1

Build: 30 Date: 16 March 2023

Schematic

53014	The IEEE Symbol "Open Emitter Pull-up" was incorrectly labeled. It has now been changed to "Open Emitter Pull Down".
53244	When using the new Variant Manager, changes to parameter values and names were not being retained. (BC:19912)
53668	In some cases, the EOleException "Specified argument was out of the range of valid values. Parameter name: Unhandled value for TUnit: eDXP" would be encountered.
53935	While open, the ActiveBOM document will now refresh automatically when any related Workspace Library components are modified and saved back to the connected Workspace.
53947	The cross reference information for a port would suddenly jump to the wrong side when directly moving the port from one wire to another.

PCB

50127	In a specific case when copy-pasting a component that is part of a union, saving and opening the target PCB would result in an Access Violation being encountered.
51041	When generating Gerber/Gerber X2 output, regions of copper were being removed from footprints when the "Merge regions and pads inside Footprint" option was enabled.
52128	In some cases, an Access Violation would be encountered when working with comments on the 2D PCB and having the 'Hide pins on design' control enabled (on the Comments and Tasks panel).
52751	In some cases, exporting a PCB to STEP would result in some models not being visible. (BC:19667)
52757	For a specific design, DRC was incorrectly flagging an 'Un-Routed Net Constraint' violation for a hatched polygon that truly had a connection to a pad.
53076	In some cases, dragging a track would result in a silent crash/termination of Altium Designer. (BC:19855)
53607	For a specific design and preferences, an Access Violation (in module ADVPCB.DLL) would be encountered after attempting to drag a track.

52753	When removing a connection point, the two bundle sections either side are now merged into a single bundle.
53215	In the Layout Drawing when adding objects to a Connection Point, the label on the Properties panel (and associated dialog) is now 'Assigned Objects' instead of 'Connectors'.
53218	When placing bundles on the Layout Drawing, 'Any Angle' is now the default placement mode when first opening the document, followed by the last style used during the current session.
53573	The Layout Drawing now supports the Connective Graph feature, to be able to see which connectors are connected to each other.
53587	The UI for defining multiple views of the physical model for a harness component on the Layout Drawing has been further enhanced.

54123	For a specific local PCB project, a catastrophic failure was encountered when attempting to make the project available online (to the connected Workspace).

Import/Export

52852	In some cases, attempting to import an Xpedition design would result in a "File not found" error being encountered.
52863	When importing an Xpedition Library footprint, the pad size was overlapping the region (custom pad) on the top layer.

47275	The control to open the Manufacturer Part Search panel from the Replace <Component> dialog (when choosing an alternate part for a variant) has been removed. (BC:17266)
47488	When acquiring a component from the Manufacturer Part Search panel into the Workspace, all datasheets were being added instead of just those selected in the Use Component Data dialog.
51416	With a Workspace project opened in two instances of Altium Designer, one instance (if closed and then opened) would need a manual refresh to see any changes made/saved in the other instance.
51560	Enhanced detection and resolution of duplicate project files, without the need to use an external VCS tool.
51638	Added the ability to export the project history into a PDF through an Output Job.
51837	Enhanced support added for admins to remove design repositories from Workspace (with validation). Also added auto-removal of repository after successful migration of external VCS project.
52297	It was not possible to add a Manufacturer Link to the ActiveBOM when the manual solution was from a custom part provider (synced to the Workspace using PrtSync).
52339	Added a warning dialog when attempting to rename the project file (or a source document) and that file is in the 'Out of date' or 'Conflict' state.
52349	Support added for layer-specific comments on the PCB (in 2D). Focusing a comment will auto-switch to the same view the reviewer had (visible layers, active layer, top/bottom view).
52351	A System.FormatException error would occur if attempting to set a non-numeric value for the Quantity field in a custom row of an ActiveBOM.
52366	The Project Releaser Item Naming Template settings are now stored in the project file, instead of the local Windows registry.
52451	The mention feature with comments does not pop a suggestion list when using the @ symbol and the local language keyboard is used (not EN).

52555	In some cases when working with comments, the error "System.InvalidCastException" would be encountered.
52587	In some cases, an EAccessViolation in module "EDMSInterface.dll" would be encountered.
52615	When adding an alternative item to the BOM, the Add Alternative Item dialog now remembers your used filters and values, just as the Components panel does.
52616	When removing an alternative group a confirmation dialog will now appear, alerting you that doing so will remove any alternate components assigned to that group from the BOM also.
52656	The active VCS status pop-up window was not displayed correctly if the Projects panel was docked in a position other than on the left. (BC:19688)
52676	For a specific project in an external SVN repository, the Open/Compare right-click commands in the Storage Manager panel would not function correctly. (BC:17509)
52984	In some cases, switching between Pro and Standard Workspaces would result in the Pro Workspace losing features/functionality.
52986	In some cases, it was not possible to add new components or edit existing components in a Workspace Library. (BC:19813)

Import/Export

49342	When importing a specific Mentor Expedition® design, holes/cutouts in copper were not being converted correctly.

Simulation

51212	The text "Output Expression" had a typo in the DC Sweep and Transient areas of the Simulation Dashboard.

52378	Added support for additional PSpice digital model primitives including flip-flops, latches, Pullup, Pulldown, Delay Line and behavioral primitive LOGICEXP.
52379	The performance of the SimData editor has been enhanced with various optimizations, memory buffering and removal of redundant calls.

52399	Added PSpice tristate gate components (AND3, OR3, XOR3, NAND3, NOR3, NXOR3, BUF3 and INV3) to the Simulation Generic Components library.

52828	The .IC and .NS components from the Simulation Generic Components library were not being added to the generated netlist.
