Release Notes - **Release date: August 5, 2026** ### Improvements #### Performance - We improved build performance and reduced memory usage of the React client when bundling with Rspack. (Ticket 282716, 282165, 282605) #### Other Improvements - We improved the security of the module import process by validating the file paths declared in an MPK package before extraction. Packages containing paths that traverse outside the app directory or target protected directories (such as `.git`, `deployment`, or `releases`) are now rejected with an error. - We fixed a bypass in the extraction-time path filter where non-canonical ZIP entry names (for example, paths containing `..` segments) could evade the protected-subtree check. Entry names are now canonicalized before filtering. - We added support for the following database versions: - MariaDB 12.3 - MySQL 9.7 - We now close the App Selector before the Open App progress dialog when the Studio Pro main window is shown. - We now delete the log files generated by Studio Pro that are older than 7 days. - We now support the environment variables `MENDIX_TRACING_FILTER`, `MENDIX_TRACING_MAX_LOOP_ITERATION`, `MENDIX_TRACING_MAX_MICROFLOW_DEPTH` in addition to system properties for the Mendix OpenTelemetry Java agent extension. ### Fixes - We fixed an issue in React client mode, where snippets would not load properly when navigating to a page with the same snippet. (Ticket 281906) - We fixed an issue that could cause an app to fail to bundle with Rspack enabled when a pluggable widget used certain Mendix modules, such as `mendix/parser` and `mendix/session`. (Ticket 282224) - We fixed an error in offline-first (PWA) apps when a list view with an association data source was opened for a context object that had not been synchronized yet. (Ticket 283531) - We fixed an issue where an editable condition set to Never could be lost during widget conversion. (Ticket 283552) - We fixed an issue where Studio Pro appeared to freeze briefly when opening an app. The progress dialog now covers the full loading process. - We fixed an issue where Studio Pro could freeze for up to several seconds during copy operations when another process held a lock on the clipboard. - We fixed an issue in Studio Pro where publishing a microflow in a new a REST service allowed adding that service to read-only modules such as the System module. - We fixed an issue where local file storage does not use optimal directory structure.
