Could you update the CHANGELOG.md?

@VladimirAlexiev care to push this over the finishing line? We'll publish the new release next week.

All that is missing is to apply our formatting rules

[steveraysteveray]

@fkleedorfer, what is the downside of running mvn spotless:apply as part of a PR build? I realize that means the src files might get changed meaning a user would need to do another git pull, but maybe that makes life easier? They will need to git pull after a merge anyway.

[fkleedorfer]

I don't see how. If it adds a commit, that would happen each time someone pushed to a PR branch, That will cause too much pain.

If it does not add a commit but cleans up the code before the other checks, it allows dirty code to enter the codebase.

[fkleedorfer]

But: if you are happy with the changes, and all that is missing is the formatting, and you have write access to the branch, you can run the format action yourself and then merge
