Git Tags
Git tags are references that point to specific commits in a Git repository, typically used to mark release points such as version numbers (e.g., v1.0.0). They provide a stable, human-readable way to identify important milestones in a project's history, unlike branch references that move as new commits are added. Tags can be lightweight (simple pointers) or annotated (full objects with metadata like author, date, and message).
Developers should use Git tags to create immutable snapshots for releases, making it easy to revert to or deploy specific versions in production environments. They are essential for version control workflows, enabling clear communication of stable points in software development, such as in CI/CD pipelines for automated deployments. Tags also facilitate collaboration by allowing teams to reference exact code states without relying on commit hashes.
