Studio release notes
April 20, 2026
Build number: 2026.0.191
Improvements
The Debug Settings and Wizards ribbon buttons now have improved menus:
- The Debug Settings menu separates toggleable settings (with visible active states) from one-time actions.
- The Wizards menu groups event-based triggers under a dedicated User Events section.
Bug Fixes
- The Studio message box did not clearly indicate that the Undo action does not apply to unversioned files in projects connected to Git.
- Intelligent code completion filter buttons overlapped with the top suggestions when configuring activity input fields in some Windows - Legacy projects.
- Bindings were being generated for assets which are part of non-publishable files.
- Projects published to Orchestrator that used TimeSpan input arguments sometimes failed to run from Orchestrator with an "Invalid format for argument 'myArgument': Cannot deserialize the current JSON object" error.
- The Recent section in the Activities panel showed activities that did not match the search query.
- Installed activities incorrectly appeared both under the Installed and Available sections in the Activities panel.
- Transient Orchestrator disconnections caused the folder context to be cleared without being restored, leading to asset lookup failures and missing feeds until a manual refresh or project reopen.
- Adding a Read Range activity from the Google Workspace or Microsoft 365 packages caused Studio to continuously reload it in some projects.

What's New
New Explorer panel capabilities for solutions
You can now browse the file structure of all project types within a solution by expanding any node in the Explorer panel. Previously, only RPA projects could be opened and explored, while other project types remained collapsed and inaccessible. This improvement makes it easier to work with all project types in a solution, including apps, agents, API workflows, and agentic processes.
You can also double-click any project file to open it directly in Studio. This allows you to view and edit raw file contents using the built-in text editor regardless of the file extension (for example, .json, .yaml, .xml, .cs, .py, .config, or .md).
A new Open with... context menu option is available for files. This allows you to open any file with its default system application or pick a specific application without manually navigating to the file on disk.
Additionally, the new Copy Path menu option allows you to copy the file or folder path to the clipboard, reducing the need to navigate to the file on disk.
Project auto-reload when dependencies change in project.json
Studio automatically reloads the project when changes to dependencies are detected in the project.json file (for example, adding, removing, or updating a dependency version), eliminating the need to manually refresh the project.
New Source Control panel features
You can now use the Generate commit message button to automatically generate a commit message based on your staged changes using Autopilot™, saving you time and improving the quality of your commit history.
Additionally, new options are available when right-clicking a commit in the panel: Checkout Branch, Revert Commit, Reset Soft, and Reset Hard.
DLL file signing
DLL files generated by Studio during publishing and at design time are now code-signed, improving compatibility with Windows Defender Application Control (WDAC) policies and reducing the number of unsigned files that need to be individually allow-listed in enterprise environments. Signing can be controlled:
- Per project: In the Publish Process window, navigate to the Certificate signing tab, where you can provide a certificate, password, optional timestamper, and enable Sign assemblies.
- Globally: In the Studio Backstage View > Settings > Locations, set a Default Publish Certificate, a Dynamic DLLs Certificate (for design time assemblies), and a Sign Tool Path.
Improvements
- You can now rename files and folders inline by double-clicking them in the Explorer panel.
- Double-clicking an Invoke Workflow File activity in a long running workflow now opens the invoked workflow directly in the editor.
Bug Fixes
- Stop Execution windows appeared unexpectedly while debugging some projects when Studio marked files as modified when opening them.
- Unexpected
Argument 'Value': BC30560andArgument 'Value': CS0433errors occurred in some projects that included libraries with Search Using SOQL activities. - The Browse for Types option could not be used when
System.Management.Automationassemblies were blocked due to group policies. - UI Automation activities sometimes displayed with a broken designer when opened in a drilled-in view.
