GitHub has introduced a new feature to streamline the management of branches after Pull Requests are processed, addressing the common issue of accumulating defunct branches once Pull Requests are merged or closed. Previously, this cleanup required manual intervention through scripting, but now users will find a convenient button to delete lingering branches directly on GitHub.com. This button appears after a Pull Request is merged, and it changes slightly when a Pull Request is closed without being merged to warn users about potential unmerged commits. This feature is accessible only to those with push access to the repository, ensuring efficient and tidy repository management.
