Release Notes - **Release date: December 2, 2025** ### Improvements - We added support for the following database versions: - PostgreSQL 18 - Microsoft SQL Server 2025 - We introduced the [batch conversion](https://docs.mendix.com/refguide/mendix-client/batch-conversion/) capability in Studio Pro for converting the old widgets that are no longer supported by the [React client](https://docs.mendix.com/refguide/mendix-client/react/). - We now cleanup expired sessions in batches instead of all at once. ### Fixes - We fixed an error in the Studio Pro installer when the installer is checking if the .NET version is already installed or not. (Ticket 253218) - We fixed an issue where unsaved changes of the System Text editor would be committed when running the app locally. (Ticket 259664) - We fixed an issue that prevented some users to authenticate in Studio Pro. (Ticket 259700) - SQLite files are now included in the service worker’s pre-cache list to ensure they are available offline. (Ticket 264140, Ticket 264910) - We fixed an error when typing invalid values in the zoom combo box on the page editor in **Structure** mode. - We fixed an issue where scheduled events with **On overlap** configured as **Delay next** would cause multiple "Skipping the update of ScheduledEvent because it's running; retrying in 7 seconds." log messages if the application was started with some time between the shutdown and the restart. - We fixed the issue that invalid sessions without an associated user were never removed from the database. - Only log 404 errors in development mode to reduce log noise in production environments. Server access logs should be used for 404 tracking in production. - We fixed a bug where the File Uploader would not be clickable when nested in a container.
