2025.10.17 release notes for Studio.

Release date: September 2, 2026

Améliorations

Manage Packages now supports the new official UiPath package feed at https://pkgs.uipath.com/official/index.json. Your installation still points to the current feed, but the new feed is already available and you can manually add it. We plan to deprecate the old feed by April 2027. A future patch will force the update to the new address.

Éditeur de code intégré pour Appeler le code

L’activité Appeler le code intègre désormais un éditeur de code alimenté par ActiPro directement sur la carte d’activité, remplaçant l’aperçu en texte brut précédent. L'éditeur fournit la mise en surbrillance de la syntaxe et IntelliSense pour C# et VB.NET, de sorte que vous pouvez écrire et modifier le code en ligne sans ouvrir une fenêtre d'éditeur distincte.

Requires System activities package 26.6.1 or later.

Résolution de bogues

• Converting a Windows - Legacy project to Windows could silently downgrade a dependency below the version another selected package required. The project then restored with an NU1605 warning and failed at runtime with a MissingMethodException. The conversion now raises the pinned versions to satisfy the requirements declared by the selected packages, and a dependency that still resolves below a requirement is marked in the Project panel with a warning icon and a tooltip naming the package that requires the higher version.
• Studio could hang on Adding dependencies... when opening medium to large projects, because the code editor re-registered a service on a syntax language that was already in use.
• Starting a debug session for a coded workflow could stop with the error Job stopped with unexpected exit code: 0xC0000354 when the .NET debugger took longer than expected to attach. Studio now waits for a late attach instead of tearing the session down, and reports that it is still waiting.
• A coded workflow debug session could hang indefinitely when attaching to the debugger failed.
• Remote debugging could fail with a The operation has timed out. error when the robot agent on the target machine took longer than the fixed 40-second wait to report that it was ready, which slow interactive logins can cause. The wait is now configurable through the UIPATH_STUDIO_AGENT_READY_TIMEOUT_SECONDS environment variable, expressed in seconds and accepting values from 10 to 1800. Values outside that range are clamped to it, and a value that is not a positive whole number is ignored in favor of the default. The variable is read once when Studio starts, so restart Studio after changing it.
• In a project mixing VB workflows with .cs coded files, spurious C# parse errors such as CS1525, CS1002, and CS1022 could appear on the VB workflows, because non-C# files were being added to the C# workspace.
• All Switch case values were silently cleared after a debug error and a rerun, because widgets could save their empty initial state over the model before their real value finished loading.
• Adding a new case to a Switch activity with a System.Char expression type threw an error, and a typed character was never saved, so new cases collided on the default key.
• Ctrl + D and Ctrl + E moved the selection to a different activity instead of disabling or enabling the currently selected one.
• Local package feeds could stay stuck loading in Manage Packages, and the Project Dependencies Mass Update Tool did not discover feeds correctly.
• The cloud catalog offered an activity that was already installed as Available, and selecting it silently upgraded the installed package.
• Importing a library did not correctly resolve the types of local and global variables.
• Running a Windows - Legacy project with Run in PiP silently ran it in the main session instead of the picture-in-picture session.
• The ST-USG-026 Activity Restrictions Workflow Analyzer rule could fail with an InvalidOperationException when several analyzer jobs ran at the same time.
• UiPath.Studio.Project.exe could crash on startup in Windows - Legacy projects because of duplicate theme resource keys, with nothing written to the Studio logs.
• In Windows projects, an error indicator could remain in front of the text in the Expression Editor while typing, hiding the expression being edited. Dismissing it by clicking elsewhere worked only until typing resumed.
• The bundled .NET 8 runtime has been updated from 8.0.28 to 8.0.30 to address known security vulnerabilities, including CVE-2026-50650.
