Version 23.9.2

Build: 47 Date: 14 September 2023

Schematic
52260 In some cases, extra junctions would appear when moving some objects on a schematic sheet.
56188 In some cases when working with a schematic document, the error "EIntfCastError: Interface not supported" would be encountered.
56320 In some cases when working with a schematic document, an Access Violation (at address 000000014B336E58 in module "AdvSch.dll") would be encountered.
PCB
53317 In generated ODB++ and Gerber X2 output for a specific design, the drill layers with microvias were incorrect for a panelized board with mixed layers.
55466 In some cases, Altium Designer would randomly and periodically freeze when performing various, different actions within the PCB Editor. (BC:20831)
55895 There was a considerable performance slowdown when adding larger numbers of stitching vias (>100,000) to a board.
56339 Changing X/Y values for a pad on an overlay layer (or the Drill Guide/Drill Drawing layer) would change the pad in the design space, but show as 0, 0 in the Properties panel. (BC:21443).
56357 A false clearance violation would occur between regular and custom shape pads when the center axis of the regular pad coincided with the edge coordinate of the custom pad shape. (BC:21381)
56744 For a specific panelized PCB, a placed drill table was not showing blind and buried vias.
56752 Vias with mixed-layer structure (blind, buried) were incorrectly rendered for a panelized PCB, but correct for the source PCB.
56772 For a design including backdrills starting from the middle of the board (using a multi-lamination process), incorrect pad sizes were being generated in Gerber and ODB++ data.
56786 When running a DRC for a Matched Lengths or Length rule from the PCB Rules And Violations panel, violations were not being presented if xSignals were used in a rule. (BC:20474)
56842 It was not possible to save a custom-defined material to the Altium Material Library as while a new row could be added and defined, the Save and OK buttons were disabled. (BC:21547)
56930 With the PCB.EngineX.ClearanceRule option enabled (in Advanced Settings), duplicating a design rule would lead to a sizable number of false violations being detected by the DRC.
57096 With PCB.Pad.CustomMasks enabled, Custom/Chamfered Rectangular pads placed on Paste or Solder Mask layers were not displayed. Sometimes, such pads would transform into tiny round pads.
57137 When using the Section View feature, the view planes were not being displayed.
57227 In some cases when using the Update from PCB Libraries feature, choosing a footprint to view comparison data would result in an Access Violation (in module "X2.EXE"). (BC:21739)
Multi-board
55587 Lines were not being displayed for the title block area after applying a template to a multi-board schematic document. (BC:21246)

Schematic
51351 When dragging all circuitry on a sheet, a power port was being included in a blanket's net class parameter set when that blanket covered the power port's original position.
53734 For a specific design, opening a particular variant, or attempting to generate output for two specific variants, caused Altium Designer to hang.

54169 Stacked thru-hole pads and vias now have their hole shapes (all types) checked to detect if one is completely within another to avoid generating duplicate drill holes in the Drill Table.
54291 A specific STEP model was being incorrectly exported (as a single part) to STEP 3D format when the PCB.OpenCascadeLatestVersion advanced option was enabled.
54308 For a specific board, moving and repouring a polygon pour would result in the previous pour area remaining visible, with no way to select or disable from view.
54360 When placing an unconnected SMD pad on a solder or paste mask layer, running a DRC would incorrectly flag an Un-Connected Pin violation.

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.
53680 Using and configuring the "Enable Fonts Replacement" feature in the Preview dialog did not result in the Stroke fonts being substituted with TT fonts in printed material. (BC:20178)
53684 False clearance violations were being returned for primitives placed on overlapping board regions in Advanced Rigid-Flex mode. (BC:20034)
53825 When exporting a board containing STEP models to Parasolid format (as a single part), some solids were being incorrectly changed to surfaces.

52857 When removing the 'System: Connector' parameter from a child project's PCB connector, the multi-board schematic was not recognizing that removal and synchronizing correctly.
Harness Design
52638 In the Wiring List table object (on a Draftsman document), the 'Gauge' parameter was incorrectly labeled 'Guage'.
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.
53616 Added the possibility to freely move multiple physical views for a harness component, on the Layout Drawing, independently of one another.

53953 When direct editing a Layer Stack item in a Workspace, the document would appear incorrectly in the Free Documents section of the Projects panel after saving.
53985 The 'Welcome to Workspace Library' screen no longer appears in the Components panel when actively working with managed components, including navigation from Web Viewer. (ВС:20321)
54008 A progress bar has been added when releasing a project and publishing it to Teamcenter EDA PLM (using a Workflow process).
54025 When attempting to clone an open Workspace project for which shared access has subsequently been removed, an empty error dialog would be encountered.

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.
54006 After exporting a PCB containing custom pad shapes to HyperLynx format, the resulting *.hyp file could not be opened in HyperLynx.
54016 For a specific DXF file, the AutoCAD Importer would throw a message that modification was not permitted with the current license and that changes were being rolled back.

53791 Added support for variable passives (resistor, capacitor, inductor).
54038 Changing the Integration Method (in the Advanced Analysis Settings dialog) had no effect on the simulation.
Power Analyzer
52837 It was not possible to probe a via on a heatmap. The probe value was the reading from the heatmap itself (Voltage Drop or Current Density) instead of the value for the pad's Via Current.
52840 It is now possible to use several extended components in parallel.
53330 In some cases, an Access Violation would be encountered after deleting a net from the *.pdnaK document.
