I do push to the -rc branches, but those branches are rebased, and I do "intermediate" pushes as well. Meaning I push to have CI systems run on the existing patch queue at times that are not only the "main" -rc release periods. Watch the branches for a few weeks to get an idea of how they work if you are curious. > > And if you can reply to the -rc release emails with a "Tested-by:" tag, > > I will be glad to add that to the release commit when that happens to > > show that you all have tested the release. > > Thanks, will reply "Tested-by:" with -rc releases.
