+Differences Between DuMu<sup>x</sup> 3.4 and DuMu<sup>x</sup> 3.3
+
+### Improvements and Enhancements
+- __Several scripts have been translated to Python__:
+    - `getusedversions.sh` to extract the used Dumux/Dune versions of a module (new script: `bin/util/getusedversions.py`)
+    - `extractmodulepart.sh` no longer creates an install file, instead, you can now generate install scripts for your module using the new script `bin/util/makeinstallscript.py`.
+    - Note: the old shells script will be removed after release 3.4.
