Update default branch to main

[domgreen]

Is your feature request related to a problem? Please describe.
Industry is moving away from terms such as master, slave, blacklist, whitelist as they have negative connotations. Many other open source projects are moving to main where possible.

Having done this internally projects on GitHub that I have migrated work fine with merging, branching and typical workflows.

Describe the solution you'd like
Update default branch to main and ensure any unseen automation continues to work.

Describe alternatives you've considered

• Could choose another default branch name if main doesnt work eg. default.
• Keep using master (not desirable)

100% in support of this.

Personally, was waiting for: https://github.com/github/renaming#later-this-year-seamless-move-for-existing-repositories- just to make things easier for everyone and not break existing tooling.

Tooling now exists 👍🏻

I'd recommend that we make the change right after the next stable release, just in case anything breaks and we need to fix it, it will give us plenty of time.

This has been done!

git branch -m master main
git fetch origin
git branch -u origin/main main

or if you use upstream to point at the main repo

git branch -m master main
git fetch upstream
git branch -u upstream/main main
