- New Constraint Manager: Ensure adherence to design rules and constraints, reducing costly errors and revisions. Constraint manager optimizes workflows, minimizes risks, and lowers production costs in the fast-paced electronic design landscape.
- Harness MCAD CoDesign: Optimize harness implementation and detect potential problems for wiring in electronic enclosures by keeping harness designs synchronized between Altium Designer and PTC Creo and Dassault Systemes SOLIDWORKS. Easily import 3D wire harness models into multi-board assemblies.
- Harness & Multi-Board System Design: Prevent costly manufacturing errors with automated design checks when working on complex harnesses. Design multiple PCBs and harnesses in a single environment, facilitating accurate system design communication to manufacturing. Automatically generate documentation and bill of materials for harness components.
- Wire Bonding: Easily validate bond wiring with Altium Designer's 3D view. Visualize bond wiring, chip dies, and die pins alongside other parts of your project in a 3D View. Simplify the verification and adjustment of parameters, ensuring greater accuracy and fit, while reducing errors and improving overall design quality.
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.
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.
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.
