Release Notes - **Release date: August 7, 2025** ### Improvements - We now remove web service user sessions if they are expired. - The navigation tree menu is no longer tagged with **aria-hidden** when it is still visible. - Menu buttons on the navigation menu are now reachable when they are visible. - We added **aria-expanded**, **aria-haspopup** and **aria-controls** attributes to the navigation tree where relevant. - We upgraded the ONNX dependency to version 1.22.0. ### Fixes - We fixed an issue in the logic editors where a caption from the **Show Message** activity did not update when switching between languages. (Tickets 247962, 250137) - We fixed an issue where the **Back** and **Forward** navigation feature did not work with styling-related files. (Ticket 252248) - We fixed an issue that prevented updated workflows from being queued for execution when Mendix Runtime crashed during startup. (Ticket 253424) - We fixed a conversion issue that occurred when upgrading apps from 9.24. Specifically, arguments of **Show a page**, **Call a microflow**, or **Call a nanoflow** [event actions](https://docs.mendix.com/refguide/on-click-event/#actions) were affected where parameter mappings changed to a different selection variable on the same page. (Ticket 253494) - We fixed an issue where a loop in a microflow did not execute if the first activity was disabled. (Ticket 253542) - We fixed an error that occurred in native offline apps when upgrading from Mendix 10.12 or below. - 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. - We fixed an issue where two different error messages overlapped in the **Choose Branch line** pane after signing in and out. - We fixed an issue where new files created during a rebase were not included in the commit. - We fixed an issue where you were unable to commit unsaved documents while rebasing. - We fixed an issue where Studio Pro crashed when opening the **History** dialog if the metadata was corrupted - 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. - We fixed a conversion issue affecting sorting in the **Gallery** widget, specifically when upgrading the data widgets Marketplace module to version 3.0.0 or above. ### Known Issues * In the React client, re-running an app locally with runtime-only changes does not properly apply those changes. (Tickets 253176, 253539, 253842, 253932, 254100) * In the React client, the debugger does not reconnect when restarting an app.
