Release Notes - **Release date: September 18, 2025** ### Improvements * We improved the exception handling of Studio Pro when necessary .NET components were missing with a user-friendly message instead of an **Oops** pop-up window. ### Fixes * Dependencies for a portable version of Studio Pro (WebView2, OpenJDK, and Gradle) are now placed inside the application's installation folder. Installing or removing a specific version of portable Studio Pro no longer affects the dependencies of other installed versions. (Ticket 244240) * We fixed an issue in Import Mappings where object properties were not connected correctly to mapped attributes, resulting in empty import values. (Tickets 254351, 256716, 256726) * We fixed an issue where keyboard shortcuts could not be used when editing JSON or SCSS files. (Ticket 256301) * We fixed an issue in the interactive documentation (Swagger UI) page for published OData services which indicated it did not support OpenAPI version 3.0.4. (Tickets 256982 and 257611) * We fixed an issue in offline synchronization (using the **Synchronize unsynchronized objects** and **Synchronize all** actions) that could result in error log statements and `System.SynchronizationError` objects containing a text *"Changing member failed for security reasons, no write access for changed member"*. That was caused by the offline client trying to synchronize a change for a member that was inaccessible by that user. * We fixed an issue when using file dialogs while the persisted file, directory, or drive no longer exists. * We fixed an issue where Studio Pro could crash due to an XPath Constraint being too long or complex to parse correctly. Now, a consistency error message is shown instead. ### Deprecations * After November 1, 2025, Mendix will drop support for the following database versions no longer supported by their vendors: * MariaDB 10.5 * Microsoft SQL Server 2019 * MySQL 8.0
