### Improved Expression Editor

We have improved the design and functionality of the Expression Editor. Some changes include:

* Fixing line spacing and text alignment.
* Improving the layout of the **Test**, **Fix**, and **Insert Variable** buttons.
* Adding dedicated **Undo** and **Redo** buttons.
* Moving the breadcrumb navigation next to the **Expression editor** title.
* Improving the experience of testing an expression.
* Allowing you to resize the area where you can write expressions using the new **Expand editor** and **Collapse editor** buttons.

### Improvements

* User-defined strings used in activity properties now have a design consistent with other UI elements.
* Saving changes made to a workflow no longer times out when updating activity properties.
* To improve the functionality of Studio Web, we have created separate buttons for **Feedback**, **Restart getting started**, and **Manage access**, making these options more visible and easier to use. Each option has its own tooltip, which appears when hovering over the button.

### Upgrade to .NET 8

Studio Web has been upgraded to [.NET 8](https://learn.microsoft.com/en-us/dotnet/core/whats-new/dotnet-8/overview), the latest version of the.NET framework.

Please note that running automations now requires robots that use the.NET 8 framework. Serverless robots are automatically upgraded to.NET 8, but if you use your own cloud robots or local robots via UiPath® Assistant, these robots must use.NET 8 to run your automations correctly. Automations published before Studio Web was upgraded to.NET 8 (August 30) are not affected.

### Use Autopilot to automatically fix activity property errors

Autopilot can now automatically fix activity property errors by selecting the new **Fix** button located on the right side of a property with errors. To learn more, refer to [Managing the activities in a project](https://docs.uipath.com/studio-web/automation-cloud/latest/user-guide/managing-activities).
