Version 2.4 of XModelerML has been released on March 28, 2025 and is available for download from the LE4MM portal. The new version significantly expands the tool’s range of functions. XModelerML and UML-MX are now available under a common interface. Users can choose between UML++ and FMMLx at runtime. In addition, class hierarchies can now be conveniently changed by removing or inserting classes. Finally, models can now optionally be saved in a database, making it much easier to search for models that have certain properties. Version 2.4.1 has been released on April 28, 2025 and fixes some minor bugs.
