Before settling for a final release, we go through a release candidate (RC) cycle. The idea is that once the codebase and documentations look ready for a release, you create an RC release by opening an issue with the release template here, starting with version vX.Y.Zrc1 and then with versions vX.Y.Zrc2, vX.Y.Zrc3...
Once the last RC is deemed ready, open an issue with the release template using the last RC version from which you remove the rc? part (i.e. v12.67.19 if your last RC version was v12.67.19-rc4) on github.
