Version 25.7.1 Build: 20 Date: 11 June 2025Schematic
64824 In some cases after updating an outdated component through the Item Manager, attempting to cross-probe to the reference part (using the 'Cross Probe - Reference Part' command from the ECO dialog's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.
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.
