Description: A branch tag is a marker applied to a specific branch within a version control system, such as Git, to indicate a milestone or a particular version of the project. This type of tag allows developers to easily identify stable or significant versions of the code, facilitating the management and tracking of changes over time. Tags are immutable, meaning that once they are assigned to a branch, they cannot be modified, providing a clear and reliable reference for the project’s state at that moment. Tags can be used to mark release versions, important milestones in development, or any other significant event that requires clear identification. In summary, branch tags are essential tools in version control systems, as they help maintain an organized and accessible record of software evolution.
