Version 24.10.1

Build: 45 Date: 10 October 2024

Schematic

61654	Instances of managed sheets placed within a design are now presented in the Web Viewer.
62392	Improved single/multi-part symbol handling, extending the same features and functionality available for Alternate display modes, to the 'Normal' display mode. (I:9891)
62663	In a specific case, a company logo graphic (in SVG format) was no longer being displayed on the schematic.
62869	When editing the values of multiple parameters for a selected component (one after another) in the Properties panel, a second click into a field was needed to edit its value. (BC:24126)
63054	In some cases when working with the Properties panel, the error "System.Runtime.InteropServices.InvalidComObjectException: COM object that has been separated from its underlying RCW cannot be used" would be encountered.

PCB

55389	In some cases when trying to change parameters for a region placed on a plane layer, through the PCB List panel, an Access Violation would be encountered.
59269	SVG geometry generated for the solder mask layer did not include cutouts (openings) for route tool paths.
59866	Added Dynamic Phase Matching support for differential pairs, including Matched Lengths rule expanded with dynamic phase matching constraints, batch DRC support and automatic length tuning with phase compensation. (I:14281)
60119	Added Routing Topology design rule as part of DRC, checking custom topologies (essentially that all From-Tos have the correct implementation).
60464	In some cases with the 'Component pushing' option set to 'Push', moving a rotated component (or a component with an irregular courtyard) would result in the component 'jumping' rather than moving smoothly.
60663	Added the ability to enable phase matching between the sides of a differential pair as part of automatic diff pair length tuning.
60883	Added support for designing hybrid boards with chip-on-board (CoB) technology using Wire Bonding. (I:3207)
61404	In some cases with the 'Component pushing' option set to 'Avoid', a component would become stuck when attempting to move it, not able to be moved smoothly as expected.
61409	With the 'Component pushing' option set to 'Avoid', moving a component did not observe the applicable clearance rule.
61587	For a polygon pour with 'Remove Necks Less Than' and 'Obey Rules' options enabled, thermal connections to pads in the polygon were incorrectly allowed to become smaller than the allowable width rule.
62084	When rerouting from an existing diff-pair using a '45/90 with arc' corner style, the arcs were not concentric.
62140	There was a noticeable delay when starting to pan within the design space, when an interactive command (e.g. Move Object, Interactive Routing, etc...) was running.
62316	For a specific design, generation of ODB++ data in either v8 or v7.1 format would result in an arc in the design being generated as a full circle.
62434	When changing the shape of a pad to 'Custom Shape', the shape used for that pad immediately before was not being applied/inherited.
62442	For a specific footprint, flipping it to the bottom layer and back resulted in a shifting of copper objects within the footprint.
62617	The Test Queries feature, in the PCB Rules and Constraints Editor dialog, was not working correctly. (BC:24002, BC:24087)
62716	The 'Footprint Mirroring Prevention' and 'Enhanced Hole Clearance Detection' features are now officially made Public with this release (both ON by default).
62788	When editing polygon and solid region corners, information for 'Radius' and 'Angles' was missing from the heads-up display. (BC:24095)
62848	The 'Enhanced Return Path Rule' feature, delivered by the PCB.Rules.CheckReturnPathVia option (Advanced Settings), remains in Open Beta but is now ON by default with this release.
62883	The 'Auto-shrinking During Interactive Routing' feature, delivered by the PCB.Routing.EnableAutoShrinking option (Advanced Settings), remains in Open Beta but is now ON by default with this release.
62899	The 'Routing Neck-Down Rule' feature, delivered by the PCB.Rules.NeckDown option (Advanced Settings), remains in Open Beta but is now ON by default with this release.
63051	Staggered vias were not being displayed correctly in 2D/3D View modes.
63057	In some cases when working with the Health Check tab on the Properties panel (for the board itself), the error "System.ArgumentNullException: Value cannot be null. (Parameter "source")" would be encountered.

PCB CoDesign

62226	Deleted primitives were not being displayed in the Conflicts region of the PCB CoDesign panel.
62457	Display of conflicts between primitives of group objects has been enhanced in the PCB CoDesign panel, with the primitive name now included before its property.
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.
61829	Added the ability to perform a one-time, one-way migration, from using the old rules management system to using the Constraint Manager.
62623	For an already-imported directive, it is now possible to add, update and remove constraints for it through the Properties panel, with changes made directly to the data in the Constraint Manager.
62626	When preparing the ECO to pass changes from the schematic to the PCB, a warning is now presented if there are directives that exist on the schematics that were not imported into the Constraint Manager.
62635	In the Physical and Electrical (Nets) views, when accessed from the Schematic, the 'Remove rule', 'Remove rules from scope' and 'Delete unmatched object' commands did not work correctly for multiple selected entities.
62785	When accessing the Constraint Manager (from PCB) for a project in Altium Designer 24.7/24.8/24.9, the All Rules view was empty. (BC:24081)
62955	In a specific case, after updating the PCB from schematics and enabling the 'Remove Clearance Constraint [xxx] All' entry in the ECO, the Clearances view in the Constraint Manager (accessed from the PCB) was empty, and subsequent attempts to synchronize (add clearance constraints from schematic side) was not possible. (BC:24181)
62966	In some cases when updating the PCB from the schematics, an Access Violation "EOleException: Value cannot be null. (Parameter "input")" would be encountered. (BC:24258)

61248	Removed a secondary, redundant dialog that was appearing when migrating a local project (under external VCS) to a connected Altium 365 Workspace's native Git repository.
61295	In some cases when working with comments, the error "System.NullReferenceException..." would be encountered.
62052	An error would be encountered when trying to make a copy of a component (through the Components panel), if the Pins panel was also docked and visible.
62182	In some cases, there was a noticeable performance degradation when conducting the first search in the Manufacturer Part Search panel.
62406	Filtering by 'Assignee' was not functioning correctly in the Comments and Tasks panel. (BC:23892)
62482	When adding a comment within the Altium 365 Web Viewer, an included apostrophe (') would incorrectly appear in HTML form (') when viewing that comment in Altium Designer.
62489	The checkbox associated with the Explorer panel's 'Show Hidden Revisions' option would disappear when switching Workspaces. (BC:22587)

62504	Added the ability, for PCB design projects stored in a connected Altium 365 Workspace, to work with system requirements defined through the Requirements and Systems Portal.
62597	Using the Explorer panel, it was not possible to drag-and-drop a project between sub-folders in a connected Altium 365 Workspace's projects folder structure. (BC:23971)
62636	When editing a Workspace component (in Batch Component Editing mode), removing a default model (taken from the associated component template) and attempting to save, would result in an Access Violation (in module 'UnifiedComponent.DLL').
62660	Within the contextual commenting window, there were no icons associated to the commands (Cut, Copy, Paste) on the right-click context menu.
62673	Attempting to drag a Workspace component entry from within the Explorer panel would result in a "System.NullReferenceException" error. (BC:23971)
62698	Added the ability to view and modify parameters for a local project template, when creating a new project in the Create Project dialog.
62729	In some cases, attempting to save a component to a Workspace (from the Manufacturer Part Search panel) would result in the "Runtime error 231" being encountered, when the user had disconnected from that Workspace on a second instance of Altium Designer.
62887	Parameters from local project templates were missing when creating a new project. (BC:24164)

61606	Empty sub-parts in alternate views of a multi-part component are now omitted during placement. (I:9891)
61822	The list of component parameters was not being automatically refreshed after choosing a replacement component through the Properties panel.

PCB

56380	In some cases when opening Altium Designer with a PCB and the (pinned) PCB Rules And Violations panel visible, right-clicking on the 'Component Clearance Constraint' entry in the panel would result in an Access Violation (in module ADVPCB.DLL).
59683	In some cases when editing an object or using an interactive command, an Access Violation (at address 000000015CEEC132 in module "ADVPCB.DLL") would be encountered.
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: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.
62407	A Clearance design rule scoped with InStructureClass vs InStructureClass was not generating DRC violations. (BC:23901)

PCB CoDesign

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.

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

56593	The menus for the 3D PCB environment are now loaded correctly from the outset, without any manual configuration required.
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.

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.

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).

Version 24.6.1

Build: 21 Date: 18 June 2024

59204	In some cases when pasting pins for a component in a SchLib and zooming in/out, the error "The parameter is incorrect" would be encountered. (BC:22466)
59709	In some cases, the error "Unable to cast COM object of type "System.__ComObject" to interface type "rt_basic.IInterfaceList"..." would be encountered.
59918	There was a rounding issue when comparing the Propagation Delay parameter and generating the ECO to update changes from the schematic to PCB. (BC:22226)
60729	When generating a PDF of project schematics through an OutJob, the order of the document bookmarks did not match the order of the sheets in the project itself. (BC:19044)

PCB

58250	Added an Advanced Settings option (PCB.Performance.UseRegionTriangulationCache) that, when enabled, improves performance of PCB loading by using regions triangulation cache.
59344	The Preview region of the PCB Layout Replication dialog has been enhanced with indication of when the preview for a selected target block is loading or updating.
59812	For a specific and large design, there was a noticeable lag when toggling visibility of various layers ON and OFF through the View Configuration panel.
60174	After annotating a schematic containing a placed Reuse Block, attempting to update the PCB with the changes would result in an Access Violation (in module 'ADVPCB.DLL').
60197	Added the ability to control whether or not drill symbols are automatically updated (live update), using the PCB.LiveDrillSymbols advanced settings option.
60489	There was a noticeable delay when starting to pan within the design space, when an interactive command (e.g. Move Object, Interactive Routing, etc...) was running.

60821	In some cases, clicking on a violation entry in the PCB Rules And Violations panel, directly after invoking the 'Run DRC Rule Class (<RuleType>)' command, would lead to an AV (in module 'ADVPCB.DLL').
60849	In some cases, there was a noticeable delay when placing a line in a PcbLib document.
60856	With PCB.Pad.CustomShape.CornerRadiusAbsolute enabled, a polygon poured around a Rounded Rectangular Pad had a distance less than that specified in the applicable Clearance rule, causing a violation. (BC:23225)
60877	After exporting a panelized PCB to Parasolid format, the file could not be opened in SOLIDWORKS.
61013	For a specific PCB design project, trying to add an ActiveBOM resulted in the error "Input string was not in correct format..." being encountered.

Constraint Manager

59200	There was no support for Differential-Pair Classes in the PCB-to-SCH Engineering Change Order process.
60454	After removing a differential pair from the Physical view, its name still remained under the diff pair class until the Constraint Manager was saved and reopened.
60459	Objects were not being selected correctly in the Constraint Manager (accessed from the schematic) after enabling the Cross Select Mode in the SchDoc.
60460	After removing a class or differential pair, the Constraint Manager had to be saved and reopened in order to be able to use Import from Directives / Create Differential Pairs successfully again.
60582	Information in the Constraint Sets region of the Properties panel was barely readable when using the 'Altium Light Gray' theme.
60611	The 'All Net Classes' scope has been removed from the Clearances view, since it is functionally identical to the 'All Nets' scope.
60617	After defining a Same Net Clearance value for a net (Physical view, Schematic) and updating the PCB, updating the PCB a second time would result in an AV (in module 'WorkspaceManager.DLL').
60679	From the Physical view, it was not possible to change the value for Min Width for a rule when an Impedance Profile was being used.
60735	With Constraint Manager accessed from schematic and attempting to add a net to a net class (with the same name), the error "An item with the same key has already been added" would be encountered.

60904	It was not possible to remove an optional rule from the 'All Nets' scope (in the Physical and Electrical views).
61012	When creating a new PCB design project, the 'Constraint Management' option is now disabled by default.

Draftsman

59535	It was not possible to access properties for a component in an Assembly view when near a Section view line. Double-clicking would select/update the Section view. Also, in some cases, selecting an Assembly view would cause the Section view near it to disappear. (BC:22765)
60475	In some cases, attempting to place a Board Isometric View into a Draftsman document would result in the error "Value cannot be null" being encountered.

3D-MID Design

58429	Added the ability to route along more 'natural' lines on the surface of the 3D substrate by using the new ‘UV’ Plane Kind for the alignment grid, whose gridlines follow the natural curves of the substrate.
59521	Added the ability to override snapping priority, making it possible to now snap to the grid when routing to/from an existing trace, rather than to that trace's centerline.
60657	Added support for placement of components onto a substrate, whose footprints contain not just pads, but also solid regions and/or fills.

Multi-board Design

58474

In some cases when trying to place a comment on a multi-board schematic, the error "Object reference not set to an instance of an object" would be encountered.

Harness Design

58698	For a specific design, attempting to import changes into the Draftsman document from the Layout Drawing would result in the error "Feature is out of the bounds of this quadtree node".
60498	When generating a BOM Violations Report from the ActiveBOM in a Harness design, duplicate designator violations were being incorrectly reported where a cavity included multiple elements (e.g. crimp and seal).
60584	The 'Where Used' feature of the Components panel did not support cavity components, cable and wire components that were used from the connected Workspace.
60592	In some cases, the Layout Drawing object in a Harness Draftsman document would not update with changes made in the source Layout Drawing document. (BC:21492)

60445	In some cases when working with the License Management view, the error "The calling thread cannot access this object because a different thread owns it" would be encountered.
60683	Added a new advanced settings option 'System.UseCefSharp123' to switch between use of CefSharp v.123 (option ON) and CefSharp v.97 (option OFF) for browser-related elements within Altium Designer (e.g., the Home page).
60848	Text in a selected cell on the System - Mouse Wheel Configuration page of the Preferences dialog was barely readable, when using the 'Altium Light Gray' theme.

Data Management

58487	Checking of Part Choices editing rights would fail if too many components in a connected Workspace were being simultaneously opened for editing.
59614	When using a Managed Schematic Sheet in a PCB design project, it would appear in the Projects panel using its Item-Revision ID, rather than its Name. (I:18534)
60318	For a specific connected on-prem Enterprise Server, intermittent and lengthy delays were being experienced when interacting with the Server through the Explorer panel.
60396	In some cases after closing a Configure dialog accessed through the Project Releaser, an Access Violation (in module "WorkspaceManager.DLL") would be encountered.
60427	Added the ability to promote favorite Filters for each component type in the Manufacturer Part Search panel.
60602	Added ability (for those with assigned operational permission) to preserve a component's current lifecycle state when releasing into a new revision.
60646	The hover text for the icon that appears in the Projects panel, when others are editing a document, now presents the names of all those collaborators.
60836	It was not possible to change a component in an ActiveBOM document with a chosen, different component from an available local library. (BC:23396)
60885	Some content generated through an OutJob would still be opened, even when the option to 'Open generated outputs' was disabled for the corresponding Output Container. (BC:23001)
60976	When editing part choices in the Component editor (batch editing mode), removing a part choice would not remove its header and adding a part choice would not reuse this empty header.
60981	When using part choices sourced from a custom part provider for a component, with identical ranking (and no supplier data), refreshing ActiveBOM would change the order of the solutions.
61016	Added the ability to use SiliconExpert data in the ActiveBOM for a non-Workspace project.

Import/Export

59103	When importing a specific OrCAD design, wires were being imported with incorrect parameters on the generated schematic documents.

57954	Adding the .PrjPcb file to its own project and then right-clicking on the main project entry in the Projects panel, would cause Altium Designer to crash and close. (BC:21967)
57991	In the Open Project dialog, changes made to columns (ordering, visibility) were not being stored, instead reverting back to defaults after a restart of the software. (BC:22286)
57995	When Downloading Sources for a previous commit of a Workspace project (from the project's history view) that historical commit would not be opened in the Projects panel. (BC:22024)
58176	For a specific PCB design project, Altium Designer would 'freeze' when opening the project's ActiveBOM document.
58180	When saving defined variants in the new Variant Manager, the data in the generated .txt file was not consistent with the view of the data in the Variant Manager.
58239	Clicking Save to Server on a specific file (in the Projects panel) will now select only that file in the Save to Server dialog.
58251	When saving a Git-controlled project to the connected Workspace, conflicted items are now always enabled for committal (and can't be disabled).
58285	After transferring ownership of a component, its history would incorrectly show the new owner as the Creator of that component.
58315	When re-releasing a symbol to a connected Workspace, the name of the Workspace was not presented correctly in the listing of components related to that symbol.
58376	In some cases when working with the Components panel, the error "System.InvalidCastException: Specified cast is not valid" would be encountered.

Import/Export

57381	xDX Designer Importer has been enhanced to better handle import of multi-part symbols, provide symbol-only import functionality and generate part-symbol and pin mapping data in CSV format.
57763	When importing an Xpedition design, Placement Outlines can now be imported as primitives on the Placement Outline layer and also as extruded bodies on Top/Bottom 3D Body assembly layers.
57932	When importing an Xpedition design, it is now possible to choose the layer from which to create extruded body shapes, storing them on the Top/Bottom 3D Body assembly layers.
58031	For a specific imported OrCAD design, the pin names for components on the generated schematic sheets were rotated.
58119	xDX Designer Importer has been further enhanced to support datasheet information, storing as a reference (ComponentLinknDescription/ComponentLinknURL parameters) in the resulting CSV file.

Circuit Simulation

57909	In some cases when working with the Simulation Viewer, the error "Object reference not set to an instance of an object" would be encountered.
58035	Output currents for P-Channel transistors (BJT, JFET, MOSFET, MESFET) are now treated as inflow currents, making them consistent with N-Channel transistors.

Ansys CoDesigner

52948

Added support for collaborative design (CoDesign) between the ECAD (Altium Designer) and Simulation (Ansys Electronics Desktop (AEDT)) domains.

Power Analyzer by Keysight

58001

Added support for assigning currents for multiple nets on the same component, for different series elements. (BC:22388)
