October 2026 release notes for Studio.
October 6, 2026
Build number: 2026.0.203
Choose the .NET version of a project
Previously, every Windows and cross-platform project was built for .NET 8. Studio now runs on .NET 10, and a new Minimum Robot version setting controls which .NET version each project is built for:
- 22.4 - .NET 6
- 24.10 - .NET 8, the default for new projects
- 26.10 - .NET 10
You can find the setting in the new project window, under Show advanced options, and in the Project Settings window. The setting isn't available for Windows - Legacy projects.
Existing projects keep their current version until you change it. Changing the version reloads the project, and Robots older than the selected version can't run the published package. For details, refer to Setting the Minimum Robot Version.
Faster switching between solution projects
Switching to another project in a solution caused the project to reload every time. Studio now keeps up to three projects loaded, so switching between them does not cause a reload. Your changes are saved when you switch away from a project.
You can control this feature from the new Fast solution project switching setting under Settings > Design > Save and Publish. The setting is on by default. For details, refer to Configuring Studio Settings.
Maestro Automate projects in solutions
You can now add Maestro Automate projects to your solution, in addition to Maestro Flow projects. Maestro Flow orchestrates a business process across agents, humans, and systems, while Maestro Automate brings AI agents and APIs together in a single workflow. Both are available from the Add to Solution menu in the Explorer panel.
You can also right-click a Maestro project and select Convert to Maestro Automate or Convert to Maestro Flow to change between project types. For details, refer to Solutions.
Improvements
- When you open a project or a solution that has a README file at its root, Studio opens the README, unless it restored your previously opened tabs. To turn this off, use the Open README file toggle under Settings > Design > Save and Publish.
- With Compact Design Experience enabled, activity cards are wider, so more of each activity's details fit on the card.
- The Else branch of an If activity starts collapsed when you add the activity.
Bug fixes
- The Arguments section of the Data Manager panel stopped refreshing after you switched to another workflow.
- Run and Debug could fail with Cannot find or create LiteDb database because Studio cleaned up a references database that another running client was still using.
- Argument default values set to an expression were ignored when Studio read a workflow's arguments.
- Command-line tools running in the Terminal panel, such as Claude Code, could choose prompt colors that were hard to read in the panel's theme. Terminal sessions now report whether the theme is light or dark.
- When an activity's type argument changed, for example when Extract Document Data switched back to
DictionaryData, the variables bound to its outputs kept their old type and reported an error. - In a solution, the visual diff of a
.xamlfile opened from the Source Control panel didn't open unless the file's project was the active one.
