In July, @tkremenek announced a plan to move the [default branch to main](https://forums.swift.org/t/moving-default-branch-to-main/38515). We are beginning the transition on September 22nd 2020 and will be changing the branch name from master to main branch for the Swift, LLVM Project, and Swift related repositories. Once this process has been completed, you will need to update the targeted branch for the pull request to match the new branch name. Push access to the old branch will be disabled on September 22nd 2020 and deleted on October 5th 2020. We will be running an automerger from the main to the master branch until October 5th 2020 to reduce the impact on downstream projects.

Swift project repositories are updated with new branch names!
