What’s new in Altium Designer 26.11.1 Build 5?
(Released on 15-10-2026)
Schematic
- In some cases when attempting to add a footprint to a component from an Integrated Library, using the Footprint Manager, an Access Violation (in module “WorkspaceManager.DLL”) would be encountered.
- In a specific design, the pin parameters for a particular connector on one of the design’s schematic documents were not being displayed.
- With a hierarchical VCS-controlled project open locally and one of its remote documents also open using the History & Version Control » Open Remote Document Version command (opening that document as a free document), attempting to jump from a sheet entry to a corresponding port (or vice versa) in the local project would result in an Access Violation (in module “AdvSch.dll”) being encountered.
- The Parameter Table Editor dialog would show all objects, even when the option to include ‘Selected Objects Only’ was enabled.
PCB
- For a specific design, Online DRC failed to observe a defined Board Outline Clearance design rule, allowing track to be routed inside a clearance boundary.
- In a specific case and when attempting to open a particular PCB, the error “Object reference not set to an instance of an object” would be encountered.
- In some cases when working within a PCB document, an Access Violation (in module “Altium.PCB.DataModel.X.dll”) would be encountered.
- For a via defined with ‘Direct’ connection style to polygon pours, if that via was placed within a same-net hatched polygon pour (set to ‘Pour Over All Same Net Objects’), but did not touch any of the pour’s hatching tracks, it was electrically unconnected, resulting in an Un-Routed Net rule violation. This release enhances support for when a pad/via is placed inside a hatched polygon pour of the same net but in a way that it does not touch tracks of the polygon pour. Now, connection is made to the nearest tracks of the polygon pour using additional tracks. (Requires the PCB.Polygon.AdvancedPour advanced settings option to be enabled).
- When viewing a PCB in 3D Layout mode, double-clicking on a component (with an associated 3D body) and choosing to select the component from the pop-up selection window, would always result in the 3D body being presented in the Properties panel, rather than that component.
- When interactively routing with the Auto Shrinking option enabled and routing Width set to its maximum value, the track would not observe constraints defined in the Board Outline Clearance design rule.
- In some cases when working with a PCB in 3D Layout View mode, an Access Violation (in module “NvPresent64.dll”) would be encountered.
- In some cases when attempting to save an older format PCB document into a later format, the error “EIntfCastError: Interface not supported…” would be encountered.
- In a specific design and with the PCB.Polygon.AdvancedPour option enabled (Advanced Settings), repouring all polygon pours, then closing the PCB without saving changes, would result in a silent crash of Altium Designer.
- In some cases when attempting to merge detected differences when using the PCB CoDesign feature, the error “object reference not set to an instance of an object” would be encountered.
- In some cases when moving/editing design primitives in such a way as to cause a design rule violation, an Access Violation (in module “ADVPCB.DLL”) would be encountered.
- Where keepout track passed through a hatched polygon pour and the applicable Clearance rule for was set to zero, attempting to repour would result in only partial repour of the polygon.
- In some cases, with the PCB.Polygon.AdvancedPour option enabled (Advanced Settings) and after performing an interactive process such as routing through a polygon pour, repouring of polygon pours would not work on the first attempt.
- When removing teardrops from selected pads within the area of a polygon pour cutout and with the Objects option set to ‘Selected only’, teardrops for other, non-selected pads within the cutout, were being incorrectly removed.
- For a specific PCB, and where the ‘Pad Vertices’ and ‘Pad Edges’ options were enabled (‘Objects for snapping’ region of Board Options) and placed pads existed on the Multi-Layer with pad size (X/Y dimensions) = 0 and Hole Size = 0, a memory leak was experienced, with memory usage for Altium Designer continually increasing during PCB editing and retained until the software was completely restarted.
- For a PCB library component with donut-shaped pads defined for its Top and Bottom layers, flipping the component from Top to Bottom layer during placement from the library (or placing from the library directly onto the Bottom layer) would result in the X-Size and Y-Size values for the Bottom layer pads incorrectly becoming the same as those defined for the Top layer.
- When deleting a polygon pour using the Polygon Pour Manager dialog, whatever was under the ‘Delete’ command ,on the dialog’s right-click context menu, was being erroneously acted upon. If the Delete command was over another polygon entry, that polygon was also being incorrectly deleted (in addition to deleting the correct one). If the Delete command was over a layer heading entry, an Access Violation (in module “ADVPCB.DLL”) would be encountered.
- In some cases, with the PCB.Rendering.DrawArcBaseGeometry option enabled (Advanced Settings) and for a PCB library containing a footprint model with placed graphics (e.g., a defined company logo), the 3D view of the footprint model was not able to be rendered in the Components panel, resulting in an Access Violation (in module “ADVPCB.DLL”) being encountered.
- With Windows system locale (in Region Settings) set to ‘Chinese (Simplified, Mainland China)’ and the ‘Use localized resources’ option enabled on the System – General page of Preferences, restarting Altium Designer and attempting to open any PCB document would result in an Access Violation (in module “ADVPCB.DLL”) being encountered.
- Attempting to edit the physical nets for a PCB, through the Configure Physical Nets dialog, would result in an Access Violation (in module “ADVPCB.DLL”) being encountered.
- With the PCB.Polygon.AdvancedPour option enabled (Advanced Settings) and in a design featuring a board region with added stiffener, adding coverlay would incorrectly create ‘Zero Area Polygons’, with the coverlay not visible with the board in 3D View nor included in generated fabrication files.
Constraint Manager
- In some cases when creating differential pairs from xNets, it was possible to create a duplicate xNet differential pair, resulting in the error “An item with the same key has already been added…” being encountered.
Wire Bonding
- Wire bonding was not being displayed correctly in the Board Section View, Component View and Board Isometric View of a Draftsman-based manufacturing drawing document (*.PCBDwf).
Harness Design
- In some cases, the Layout Drawing view was not visible after importing changes from a harness design’s layout drawing into its harness manufacturing drawing.
- For a specific harness design, attempting to import changes into the harness manufacturing drawing from the underlying layout drawing would result in the error “System.ArithmeticException: Function does not accept floating point Not-a-Number values” being encountered.
Platform
- In some cases when viewing a browser-related element within Altium Designer using WebView2 (e.g., the Home page), the error “System.Runtime.InteropServices.COMException: The object invoked has disconnected from its clients…” would be encountered.
- For users of the extensions ‘EMI Design Rule Checker’ or ‘Plane Resonance Analyzer’, attempting to launch those features from the main menus in a PCB document would result in termination of Altium Designer.
- Where multiple users are using the same computer, only the user who originally installed Altium Designer would be able to start it successfully. Other users would encounter the error “Runtime Error 217”.
- With the UI.ProjectOptions.SearchPaths option enabled (Advanced Settings) and having added a search path to the Search Paths tab of the ‘Options for Project’ dialog, clicking on the Refresh List button would result in the error “Type ‘Altium.WorkspaceManager.DataModel.SourceDocumentAdapter’ has a ComVisible(false) parent…” being encountered.
- Additional ‘Third Party’ notices, that were removed from the Copyright notices dialog in Altium Designer 26.10, have been added back in this release.
Data Management
- In some cases while working with the Project Releaser, an Access Violation (in module “ProjectReleaser.dll”) would be encountered.
- It was not possible to rename a harness wiring model through the Component editor, when configured in its Single Component Editing mode. In some cases, the preview of the model would also disappear.
- When placing a comment in a document of a design that had been shared and assigning it as a task to a specific user, the task was being created without the assignee.
- After sharing a Workspace project with an external user (not a member of that Workspace) and adding a task (assigned to them) through the browser interface, that task was not displayed for them in Altium Designer’s Comments and Tasks panel (after opening the ‘Shared With Me’ project) unless they were connected to the Workspace.
- When creating a new Jira Issue from a placed comment, ‘(optional)’ labels have been added to better indicate which fields (Description and Assignee) are optional.
- When releasing changes to a Workspace model into a new revision, you now have the ability (for those with assigned operational permission) to preserve the current lifecycle state for associated Workspace components that reference that model. The current lifecycle state of the model itself is no longer preserved. Note that this applies only to a Workspace on the Altium Platform.
- It was not possible to paste fractional values into existing template-sourced parameters, when editing components in the Component editor (in its Batch Component Editing mode). Such values would be rounded to the nearest integer value.
- Defined process-based workflows for a connected Workspace, available from the Project Activities and Project Releaser sub-menus, were not being updated when switching between connected Workspaces, resulting in the error “Process definition not available”, when attempting to invoke them.
- When releasing a component or design project into a connected Workspace for the first time and creating the related item(s) in that Workspace, a CMD script is no longer run in the temporary folder (e.g., C:\Users\<UserName>\AppData\Local\Temp) to create a Zip (using 7za.exe) of those items for upload to the Workspace.
- When releasing a design project using the Project Releaser, it was incorrectly possible to get into a state where existing data for a previous release (e.g. Fabrication data set) was being modified with that of a later release.
- Enhanced the filtering controls in the Comments and Tasks panel. The default filtering state is for all types to be enabled (Comments, Tasks and Jira Issues), the scope (‘Current document’; moved from the settings window) to be disabled and all assignees (assigned tasks or Jira issues) to also be disabled. The filter button will now turn blue only if the filtering state is not the default. In addition, a ‘Clear Filters’ control is available to quickly return filtering to its default state.
- Added the ability to copy-paste system parameters when editing a component template, with the ability to paste between template documents.
- When using the Component editor in its Batch Component Editing mode, and where a defined component uses parameters to define its Name and/or Description, making a copy of that component now keeps the use of those parameters in the Name/Description fields for the new component, instead of plain text.
- When defining operation permissions for a connected Workspace (through the Edit Operation Permissions dialog), it was not possible to add the ‘Workspace Members’ entity back, if removed from a particular operation type.
- When using the Operations » Export Grid command with selected components in the Explorer panel (in Classic View or Components View) and the ‘Show only latest’ option is enabled, only the latest revisions of those components will now be exported and not all revisions, as was the case previously.
- When configuring a Bill of Materials report (direct or through an OutJob), attempting to modify filtering through the Filter Editor dialog would lead to the error “Object reference not set to an instance of an object” being encountered.
Import/Export
- When importing a KiCad version 9 or 10 design file, layer mapping was incorrect, with mechanical layers being mapped to signal layers.
- When importing a KiCad version 10 design file, net information was not being imported, resulting in copper primitives set to ‘No Net’.
