 - Added an option in the app settings to create an encryption secret, which is required to encrypt values (for example, API keys) in configuration plugins. This feature only shows up when administration options are enabled.
 - Improved the document analysis assistant (in beta) by hiding the export functionality by default. Enable the administration options in the app settings to show and use the export functionality. This streamlines the usage for regular users.
 - Improved the workspaces experience by using a different color for the delete button to avoid confusion.
+- Fixed an issue where manually saving chats in workspace manual-storage mode could appear unreliable during response streaming. The save button is now disabled while streaming to prevent partial saves.
 - Upgraded dependencies.
