Release Notes - **Release date: April 24, 2026** ### New Features #### Portable App Distribution (Beta) Portable App Distribution revolutionizes server deployments and simplifies local testing by packaging applications as self-contained zip files that include all dependencies, scripts, and configurations for instant deployment across any environment. This approach eliminates complex installation procedures while providing flexible HOCON-based configuration management for seamless operations across development, testing, and production environments. For more information, see [Portable App Distribution](https://docs.mendix.com/developerportal/deploy/portable-app-distribution-deploy/). ### Improvements - We added a **Refresh schema** button to the mapping editor toolbar. This button appears when the mapping is out of sync with its underlying schema, allowing you to update the mapping elements to match the current schema directly from the editor. - We upgraded the BouncyCastle dependency to version 1.84. (Tickets 276629, 276631) ### Fixes - We fixed an issue where saving changes in the **Select Elements** dialog of an XML import mapping incorrectly allowed saving an invalid selection where a parent element was checked but its required child element was not, without showing the expected error "Element '…' cannot be checked without a checked child element." (Ticket 273820) - We fixed an issue in the **Select Elements** dialog of an XML export mapping where clicking OK on a checked parent element whose required child elements had not been expanded caused the error "Element '…' cannot be checked without a checked child element." Studio Pro now automatically checks required child elements of unexpanded parent nodes before saving. (Ticket 274683) - We added an additional fix for cases where an external keyboard would not traverse properly through elements marked as accessible on mobile devices. - We fixed a runtime exception in Published OData when publishing an association to an object that is inaccessible due to OData security constraints. - We fixed a runtime error in OData search queries for varchar attribute with a limited column length and a search string longer than that limit. - We fixed an issue in the JavaScript Action Editor where multiline import statements were not parsed correctly.
