+### Changed
+
+- Removed directory `Documentation/version-control` which contained the Git hooks. The Git hooks are not required anymore. Instead, added `git rev-parse HEAD` to file `VadereSimulator/pom.xml` to create `VadereSimulator/resources/current_commit_hash.txt` during each build via `mvn compile`.
+  **Note:** The file `current_commit_hash.txt` is created during Maven's validation phase, i.e., before the actual build.
