10. Tagging & Versioning

Tags mark specific commits as release points.

# Lightweight tag (just a pointer)
git tag v1.0.0

# Annotated tag (recommended — includes message, author, date)
git tag -a v1.0.0 -m "Initial stable release"
git tag -a v1.2.0 a3b2c1 -m "Tag on specific commit"

# List tags
git tag
git tag -l "v1.*"           # filter

# Show tag details
git show v1.0.0

# Push tags (tags are NOT pushed with git push by default)
git push origin v1.0.0          # push one tag
git push origin --tags          # push all tags

# Delete tag
git tag -d v1.0.0               # local
git push origin --delete v1.0.0 # remote
