As a first step after yesterday's community meeting I've enabled koji-testing build in copr. It is a step ahead compared to my original "master" repo. So, now you can use:
Repo which uses master branch and is built once per four hours if there is anything new in git
Repo which uses master branch + merged all "testing-ready" PRs. This build is used by our internal QE for testing actual content. (Can be often broken due to automatic merging)
