Releasing

1. decide right version (use semantic versioning scheme)
2. run the release using ./release.sh -v <decided version> -g <gpg password>
3. close current milestone (and possibly create new)
4. create a new release
5. wait for Maven Central sync

In case the release script somehow fails, or you don;t like the magic, you can go the old way

1. release using Maven release plugin mvn release:prepare release:perform
2. push changes to git
3. change version in README.md
4. git push origin --tags HEAD
