Release procedure

1. Test the application manually at least for basic functionality.

   • Use semver to pick version number.
   • Minor and major releases should be created from master branch.
   • Patch releases should be created from release/x branch.
3. Verify that images were uploaded to the registry.
4. After creating new major or minor release create a new release branch (i.e. release/1.2).
5. Update the version in the kubermatic/kubermatic repo.
   • If the release is only nice to have (not urgent) and should not cause new release of the whole application mark it in the pull request.
