 ### Other New Features
 
 - We introduced a modernized **Variables** pane. It now preserves expanded nodes as you step through the debugger, so you no longer lose your place between steps.
-- The modernized Debug Windows can be switched off in **Edit** > **Preferences** > **New features** by unchecking **Use the modernized Debug Windows (Requires restart of Studio Pro)**.
 - We improved offline synchronization error handling so that when the server rejects uploaded objects (for example, due to validation rules or security constraints), the synchronization action now throws a `PartialSynchronizationError` (as long as **Throw error when server rejects objects during synchronization** option is enabled). Nanoflow developers can catch this error in a try/catch block to present a message to the user or take corrective action.
 - Toggling the web fetch tool in Maia preferences now takes effect immediately, without needing to relaunch Studio Pro.
 - We added the ability for the user to see the current Studio Pro version through the Preferences API.
