Default branch renamed from master to main

[andrew]

The default branch has been renamed from master to main. GitHub will handle redirects for most things automatically (web URLs, cloning, etc.), but if you have a local clone you'll want to update it:

  git branch -m master main
  git fetch origin
  git branch -u origin/main main
  git remote set-head origin -a

If you have any open branches based on master, they'll continue to work fine — just target main when opening PRs from now on.

Any local scripts or aliases that reference master should be updated to main as well.
