Branches are a crucial component of collaboration in GitHub Flow, offering an efficient way to manage project development within a repository, and GitHub is enhancing branch management to make it more user-friendly. By clicking on the Branches tab at the top of any repository page, users can access an overview of all branches in their project, allowing them to filter for specific branches and identify the most active ones. The updated interface also clearly indicates necessary actions, such as cleaning up stale branches, addressing branches with failing tests, or initiating pull requests for newly pushed branches. For further assistance, users can refer to GitHub Help for detailed guides on creating, deleting, and viewing branches.
