Release Notes

Version 26.1.0

The file MANIFEST.MF contains information that is read by Faktor-IPS when an IPS project is read as a Maven dependency. It will now be automatically updated with all current Faktor-IPS settings during every full build. Previously, the MANIFEST.MF was only rewritten during certain migrations

The Product Definition Perspective has been extended with the action set "Launch". This makes the "Run" menu available in the menu bar within this perspective as well. For example, Maven targets can now be launched directly from the Product Definition Perspective.

The Product Definition Explorer has been extended with three new features:

  • "Open With" context menu entry – similar to the Project Explorer, elements can now be opened with a different editor.

  • "Team" functions – GIT integration features are now also displayed.

  • Number of selected objects is displayed in the status bar

Many instances of Faktor-IPS not correctly writing changes made in the UI, have been fixed.

Compatibility

Java

Faktor-IPS 26.1 requires at least Java 21 and has been tested for compatibility with Java 25.

Eclipse

The design time Eclipse plugin requires at least Eclipse 2024-09 and has been tested with that version and all following versions up to and including Eclipse 2025-12.

We currently recommend using Eclipse 2025-06 or later. Eclipse 2025-03 is not recommended due to a false compiler error (JDT Bug #3775).

Maven

For use of the Faktor-IPS Maven plug-ins at least Maven 3.9.9 is required for our Maven plugins. Using older versions may lead to build errors.
