Studio release notes
Last updated Apr 7, 2026
2025.10.8
Release date: April 6, 2026
Improvements
The ST-USG-014 - Package Restrictions Workflow Analyzer rule now supports:
- More than 250 characters
- The less than (<) and less than or equals (<=) symbols
These improvements make the rule more flexible for both allowed and prohibited packages.
Bug fixes
- The Browse for Types option could not be used when
System.Management.Automationassemblies were blocked due to group policies. - The Output panel incorrectly converted ISO 8601 datetime strings to the standard datetime format.
- Unexpected assembly resolution errors occurred at runtime in some projects referencing libraries built with UiPath.System.Activities version 22.10.3 and published from Studio 2025.10.x. Studio now resolves assemblies correctly, preventing these runtime errors.
- IntelliSense suggestions were covered by functional icons in Windows - Legacy project input fields.
- Some debugging sessions in projects with libraries failed with an unexpected "Unable to start execution" error when paused at a breakpoint.
- Renaming arguments in a library added as a dependency and republishing the library caused the custom activity to not display as expected after updating the library version.
- In Windows - Legacy projects, the Expression Editor opened blank when editing conditions in Do While or While activities.
- 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.
- Studio became unresponsive when using dynamic target properties with objects linked to the Object Repository.
- UI Automation activities sometimes displayed with a broken designer when opened in a drilled-in view.
- Stop Execution windows appeared unexpectedly while debugging some projects when Studio marked files as modified when opening them.
- The Studio message box did not clearly indicate that the Undo action does not apply to unversioned files in projects connected to Git.
- 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.
- Unexpected
Argument 'Value': BC30560andArgument 'Value': CS0433errors occurred in some projects that included libraries with Search Using SOQL activities. - The CurrentRow activity option was not visible in some projects that contained
UiPath.Excel.Activitiesversion 3.4.1.
