Release Notes - **Release date: August 15, 2025** ### Fixes - We fixed an issue with offline synchronization that resulted in error log statements and *System.SynchronizationError* objects containing messages such as *Changing member failed for security reasons. No write access for changed member*. This error was caused by the offline client trying to synchronize a change for a member that was not accessible for that user. (Ticket 244684) - We introduced a feature flag `--md-disable-association-expand` that disables auto-expanding associations in the **Message Definitions** editor. This makes it easier to open and edit complex **Message Definitions** as it limits the number of visible tree elements. (Ticket 253206) - We fixed an issue that prevented updated workflows from being queued for execution when Mendix Runtime crashed during startup. (Ticket 253424) - We added the ability to remove Mendix Studio Pro versions directly from the Version Selector interface when traditional uninstallation failed due to corrupted Windows registry paths, givingusers a manual cleanup option. - In the Dojo client, we fixed a pop-up window resizing issue that occurred upon interacting with a combobox widget inside the popup on mobile devices. ### Known Issues * Line endings in CSS files are not being handled properly, so when using [Revert All Changes](https://docs.mendix.com/refguide9/using-version-control-in-studio-pro/) or performing other version-control operations, CSS files appear in the [Changes on Disk](https://docs.mendix.com/refguide9/version-control-menu/#show-changes) dialog box. * Workaround: For details, see [this section](https://docs.mendix.com/refguide9/troubleshoot-git-issues/#css-error) in *Troubleshooting Version Control*.
