What is the suggested flow for the forked repositories? The forks would probably need to make adjustments: either rename the branch or re-target the branch (and update CI configuration).
I don't think a volunteer can help with updating forks including private ones :( Even if we rename `master` branch, Calcite would still use the labor of Jenkins slaves that are controlled by Jenkins master to verify Calcite quality. Does that mean we must stop using Jenkins immediately? AFAIK there's just one week left before https://builds.apache.org/ decommission (~15 Aug or so), so we need to migrate to https://ci-builds.apache.org/ or reject Jenkins to avoid slavery. -- Just in case: as a non-native speaker, I treat "master branch" and "main branch" virtually indistinguishable. However, "master branch" has a strong reference to the name of a Git branch, while "main branch" sounds more like "a branch which is used a main for some reason". In other words, "main" does sound like a significantly broader term, and it might require extra clarification when used. Vladimir
