Release Notes - **Release date: September 11, 2025** ### New Features * The **Changes** pane will now automatically be updated if files on the disk are changed outside of Studio Pro. ### Improvements * We added support for converting [data grid 1 columns](https://docs.mendix.com/refguide/columns/) (ones configured over reference sets) into [data grid 2 columns](https://docs.mendix.com/appstore/modules/data-grid-2/#columns). * Pushing commits to the server is no longer possible if there is nothing to push. ### Fixes * We fixed a rare issue where an error pop-up window could appear if a user attempted a version control operation while Git optimization was running for an extended period of time. (Ticket 246741) * We fixed an issue where an **Oops** pop-up window appeared during deployment if multiple pages using the same snippet are processed simultaneously. (Ticket 254648) * We fixed an issue where a consistency error for offline profiles ("Specialization Entity should have an offline synchronization mode as its generalization Entity has an offline synchronization mode") was wrongly reported. (Ticket 255323) * We fixed an issue on offline-associated entities pertaining to `startsWith`, which is not a function error in synchronize actions. (Ticket 257346) * We fixed an issue where database synchronization would fail when all of the following occurred during the same deployment: (Ticket 258046) * An association in the database contained any dangling references * Foreign key constraints were newly enabled * The association storage was changed to or from being a direct association * We fixed an issue where an **Oops** pop-up window was displayed when switching the data source type of a combo box. * We fixed an issue when using file dialogs while the persisted file, directory, or drive no longer exists. * We fixed an issue for **Export Mappings** where it was incorrectly possible to clear the **Message Definition** root element from the **Select schema elements** tree structure. * We fixed an issue for **Import Mappings** and **Export Mappings** where a user would select a checkbox in the **Select schema elements** tree structure 5 levels deep or more, and the tree failed to expand itself to show children items. This made it possible to not select required schema elements. * We fixed an issue for **Export Mappings** where XSD extension attributes checkboxes in the **Select schema elements** tree structure were incorrectly not selected when the user selected the checkbox of their parent attribute. * We fixed an issue where importing modules containing files with paths longer than the maximum length failed to throw an error message. It will fix these support issues: * 227963: "Can't import the Nanoflow Commons to 10.6.x_Maintenance branch line" * 234259: "Importing Nanoflow commons impossible" * We fixed an issue where the **Push** button is disabled after opening an app with local commits while auto-fetch is disabled. * We fixed an issue where user gets an **Oops** pop-up window when creating a non-versioned app. ### Deprecations * From November 1, 2025, we will drop support for the following database versions that are no longer supported by the vendors: * MariaDB 10.5 * Microsoft SQL Server 2019 * MySQL 8.0
