 ## Steps
 
-1. Create a release branch from the dev branch. This prevents further changes
-   to the code base and a never ending release process. Naming: `release-<VERSION>`
+1. Create a release branch from the dev branch. This prevents further changes to
+   the code base and a never ending release process. Naming:
+   `release-<VERSION>`. Also create a branch with the same name in cppinttests.
 
 2. Update CHANGELOG.md
 
 3. Check all general prerequisites.
 
-4. Prepare [CMakeLists.txt](./CMakeLists.txt): Check the `MAJOR`, `MINOR`, `PATCH`
-   version variables.
+4. Update version numbers:
+   1. In [CMakeLists.txt](./CMakeLists.txt): Check the version variables and
+      make sure that the compatible caosdb-server version is set correctly.
+   2. In `conanfile.py`: Update the `version` variable.
+   3. In `caosdb-cppinttest/conanfile.py`: Update the version
 
 5. Merge the release branch into the main branch.
 
-6. Tag the latest commit of the main branch with `v<VERSION>`.
+6. Tag the latest commit of the main branch with `v<VERSION>`. Push the tag and the main branch.
 
-7. Delete the release branch.
+7. Create release in Gitlab:
+   1. On [Releases](https://gitlab.indiscale.com/caosdb/src/caosdb-cpplib/-/releases), click "New release"
+   2. Choose tag, type release title (same as tag), no milestone, possibly short release note, no
+      manual assets are necessary, possibly link to documentation.
 
-8. TODO...
+8. Delete the release branch.
+
+9. Release cppinttests with updated cpplib version
+
+10. Merge `main` back into `dev` and increase patch version by one to begin next
+    release cycle. Do the same in cppintest.
