Git Tag Usage Guide: Best Practices for Marking Important Versions

Git tags are permanent markers for specific commits in a Git repository, used for version management, quick rollbacks, and team collaboration. They differ from dynamic branches (which move with development, while tags are static points). Tags are categorized into two types: lightweight tags (simple, no extra information, suitable for temporary marking) and annotated tags (formal, containing creator details, comments, etc., for official releases). The creation commands are `git tag v1.1` and `git tag -a v1.0 -m "Comment"`, respectively. To view tags, use `git tag` (list tags), `git tag -n` (list tags with comments), and `git show v1.0` (view details). For management, local deletion is done with `git tag -d v1.0`, remote deletion with `git push origin --delete v1.0`, and pushing with `git push origin v1.0` or `--tags` to push all tags. Best practices include following Semantic Versioning (MAJOR.MINOR.PATCH), prefixing with `v`, tagging only stable versions, ensuring tags are immutable, and synchronizing with the team. Proper use of tags ensures clear and controllable versions, facilitating collaboration and maintenance.
