@pregnor @fekete-robert We shouldn't merge this before the next Koperator release is dropped, right?

I guess so, but I'm lost what is auto-released and what is not so I defer to Robi's answer.

yea... I started to think that we might need to use release tag, so that committing to master branch wouldn't make the commit public

@pregnor @panyuenlau : Stuff from the master branch is not published automatically, but new merges automatically open PR for the banzai site. So we can either mark the PR with something like Do not merge until X.Y release, or we can merge it, and then I'll (hopefully) keep in mind that we shouldn't publish updates to the koperator docs on the banzai site.

This will improve when we migrate the docs and the code to the new github org, where we can have versioned docs, and have a separate set for version X.Y, and also a latest greatest build from the main branch.
