Repository files navigation

Many communities, both on GitHub and in the wider Git community, are considering renaming the default branch name of their repository frommaster. GitHub is gradually renaming the default branch of our own repositories frommaster tomain. We're committed to making the renaming process as seamless as possible for project maintainers and all of their contributors. This repository is our up-to-date guidance on how and when to rename your default branch.

We're not the only organization in the Git ecosystem making these changes: there are upcoming changes in the Git project (statement,code change), as well as coordinated changes from multiple vendors.

We're making changes to GitHub in a few phases, designed to cause as little disruption to existing projects as possible.

• We've updated GitHub.com to redirect links that contain the deleted branch name such asmaster to the corresponding link in the repository's new default branch.
• We've updated GitHub Pages to build and deploy from any branch.
  • Note: publishing to the specialgh-pages branch will still work the same as it always has, but now you can choose any other branch in your repository as the publishing source.
  • Note: If the branch used by GitHub Pages is renamed, your GitHub Pages site will be unpublished. Pushing a new commit to the renamed branch will republish the site.
• We've added user, organization, and enterprise settings to set the default branch name for all newly-created repositories on GitHub.com. We're adding the same settings in the 3.0 release of GitHub Enterprise Server.
  • These settings cover repositories created throughGitHub.com and theGitHub API. Git 2.28 added a similar setting to control the default branch used when you rungit init on the command line. Learn more about the newinit.defaultBranch setting inthe Git 2.28 blog post.
  • GitHub Desktop has introduced a default branch setting for new repositories.
• We've made it easier to rename an existing branch
• We've updated Gists to use your preferred branch name

The default branch name for new repositories created on GitHub is nowmain. To set a different default:

1. Forusers, on thehttps://github.com/settings/repositories page
2. Fororganization owners, on thehttps://github.com/organizations/YOUR-ORGANIZATION/settings/repository-defaults page
3. Forenterprise administrators, on thehttps://github.com/enterprises/YOUR-ENTERPRISE/settings/member_privileges page

Users, organizations, and enterprises that previously selected a default branch for new repositories are not impacted by this change. Existing repositories are also not impacted by this change.

main is the most popular replacement formaster that we're seeing across GitHub. We like it because it's short, it keeps your muscle memory intact, and it translates well across most languages. We're usingmain for our newly-created repositories and for the repositories we're moving now, likedependabot-core.

You can now rename any branch, including the default branch, from the web.

Renaming a branch will:

• 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
• Update the branch used to build GitHub Pages, if applicable
• 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 whogit 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
