Git 2.31.0 (2021-03-15) ¶

Python 3.11 (2021-03-03) master => main ¶

Introduction ¶

Hi,

I am writing on behalf of the Python Release Management team. The Steering Council has requested the RM team to schedule and perform the necessary changes to rename the default branch from master to main.

The changes ¶

What follows is the technical description of the changes and the timeline. In order to keep this thread focused on this particular aspect, if you wish to discuss anything related to the change itself, please, open a new email thread or reuse an existing one.

The change will be executed when beta 1 is released, as the beta 1 release requires some branching engineering already to create the 3.10 branch and point 3.11 to the new one as well as changing CI, buildbots…etc This is scheduled for Monday, 2021-05-03.
The CI will be adapted to work with the new “main” branch.
The buildbots will be adapted to work with the new “main” branch.
Branch protection rules will be adapted.
The different bots will be adapted by the respective bot maintainer teams.
All the URLs that point to master in the README and other places will be adapted to point to main instead (notice this is not strictly necessary because GitHub redirects automatically).

Notice that the renaming will automatically:

Re-target any open pull requests
Update any draft releases based on the branch
Move any branch protection rules that explicitly reference the old name
Show a notice to repository contributors, maintainers, and admins on the repository homepage with instructions to update local copies of the repository
Show a notice to contributors who git push to the old branch
Redirect web requests for the old branch name to the new branch name
Return a “Moved Permanently” response in API requests for the old branch name

Check this https://github.com/github/renaming for more information.

What you need to do ? ¶

You just need to update your local clone after the branch name changes. From the local clone of the repository on a computer, run the following commands to update the name of the default branch.

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

           

Apart from that, you should update any local script or command that uses the name “master” to use the name “main”.

gitlab The new Git default branch name Why we’re joining the Git community and updating “master” to “main” ¶

https://about.gitlab.com/blog/2021/03/10/new-git-default-branch-name/

GitLab has already introduced changes that allow users to change the default branch name both at the instance-level (for self-managed users) and at the group-level (for both SaaS and self-managed users).

To further align with the community, we will make the following changes in the upcoming releases:

Default branch name changes for GitLab.com and self-managed users: When creating a new project in GitLab, the default branch name will change from master to main. We are planning to implement this change in two phases:

Phase 1: ¶

We plan to update GitLab’s underlying Git version to 2.31.0 as part of GitLab’s 13.11 release, shipping on April 22, 2021.

The branch name change will be shipped under a feature flag. Projects created from GitLab will continue to the current default branch name of master.

Phase 2: ¶

We will remove the feature flag as part for our next major release 14.0, shipping on May 22, 2021.

Any project created in GitLab will use the default branch name of main.

Action required: When upgrading a self-managed instance to GitLab 14.0, new projects created via the GitLab GUI will use main as the default branch name.

If your project is running CI/CD jobs configured in another project, hard-coded references to master will need to be updated to use either main or to use a default branch name CI/CD variable, such as CI_DEFAULT_BRANCH.

You can continue to use master by configuring a custom default branch name.
