Release Notes - **Release date: February 9, 2026** ### Improvements - We have improved the performance of session cleanup. ### Fixes - We fixed an issue where System.UserRole's **Description** attribute was not readable. (Ticket 259857) - We fixed an issue where the short revision hash of the commit was being sent when deploying a package. (Ticket 264621, Ticket 266012) - We fixed an issue in offline apps that could result in errors like "[Synchronization] SQLiteError: table mx10414574138294561$_guidToTable has no column named inaccessibleAttrs" by ensuring database migrations happen properly for all users in the client database. (Tickets 264910, 265393, 269740) - In the logic editors, we fixed an issue where extracted microflows did not contain all the expected parameters for a newly-created activity. (Ticket 265542) - We fixed an issue with the [tab container](https://docs.mendix.com/refguide10/tab-container/) widget. It would reset to the first tab when returning to the page, causing data sources to reload unnecessarily and other tabs to be blocked. (Tickets 266083, 266090, 267249) - We fixed an issue where the last attributes were truncated in entity properties dialog boxes. (Tickets 266554, 260953, 256106, 251278, 255882) - We fixed an issue where an import mapping would not read JSON attribute values when a JSON attribute was preceded by another attribute with an attribute name that is a prefix (for example `StatusId` and `Status`). We also improved how JSON objects were read when one object name was a prefix of another object name. (Ticket 266571) - In the logic editors, we fixed an issue where a **Show Message** activity had an empty caption after initial loading of the microflow. (Ticket 268024). - We fixed an issue that caused setting the image of a building block to show an error dialog instead of resizing the image. (Ticket 268856) - We fixed an issue in Maia chat where it crashed if the **Studio Pro Version** attribute was missing in a reference. - We fixed scenarios in Android where navigating fields of a data view (of different types) would not be possible using an external keyboard. - We now parse `StdOut` and `StdError` streams separately when calling git process. This improves the stability of git operations. - We fixed an issue during local development where system texts would not be updated in the application when hot-reloading. They are now correctly updated without the need to fully restart the server.
