Core Engine Release 4.48

November 2025

We upgraded! What's new? Learn more about new features, technical changes and solved bugs in 4App Core Engine.

Note on upgrading: If you skip a version when upgrading, check all release and patch notes in between for important information. They apply cumulative.
Note on individualization: If your 4ALLPORTAL is highly customized or if you installed individual apps, please contact your implementation partner before upgrading. We recommend checking your custom contents, especially layouts and object renderers, carefully after an upgrade.

Technical Changes & Admin Instructions

Prevent Manual Updates for Managed 4Apps

All 4Apps listed in the APPS_INSTALL environment variable in your docker-compose file are now marked as automatically managed. You cannot update or deactivate them via the UI or the API anymore. Attempting to do so will result in an error.
Please note: The Core Engine is always treated as a managed 4App.

Metrics

We have introduced metrics to monitor and analyze operations relating to the creation, updating and deletion of objects, including bulk modifications.
