GitHub is introducing a new feature called Protected Branches, aimed at preventing accidental overwrites by disabling force pushes to specific branches, thereby safeguarding collaborative work. This feature allows repository administrators to designate branches as protected, which not only blocks force pushes but also enforces required status checks through the Status API. These checks ensure that branches are up-to-date and that tests will pass before any merging occurs, with the option to disable the merge button until they do. The "Update branch" button, part of this feature, facilitates merging the latest changes from the base branch of a Pull Request with just one click, enhancing the integrity and reliability of collaborative coding efforts.
