Tag Naming Conventions

Standard Format

v1.2.3-beta.1   # Pre-release
v2.0.0-rc.1     # Release candidate

Creating Tags

Annotated Tags (Recommended)

Annotated tags store metadata (author, date, message):

# Create annotated tag
git tag -a v1.0.0 -m "Release version 1.0.0"

# Create with detailed message
git tag -a v1.0.0 -m "Release version 1.0.0

Features:
- User authentication
- Dashboard redesign

Fixes:
- Login timeout issue (#123)
- Memory leak in worker (#456)"

Lightweight Tags

Simple pointer to a commit (no metadata):

git tag v1.0.0

Tag Specific Commit

# Tag a past commit
git tag -a v1.0.0 abc1234 -m "Release version 1.0.0"

Managing Tags

List Tags

# List all tags
git tag

# List with pattern
git tag -l "v1.*"

# List with details
git tag -n

# List sorted by version
git tag -l --sort=-v:refname

View Tag Details

# Show tag info and commit
git show v1.0.0

# Show just the commit
git rev-parse v1.0.0

Delete Tags

# Delete local tag
git tag -d v1.0.0

# Delete remote tag
git push origin --delete v1.0.0
# or
git push origin :refs/tags/v1.0.0

Pushing Tags

# Push single tag
git push origin v1.0.0

# Push all tags
git push origin --tags

# Push only annotated tags (recommended)
git push origin --follow-tags

Version Bump Workflow

1. Determine Version Type

Changes Made	Bump Type	Example
Breaking API changes	MAJOR	`1.2.3` -> `2.0.0`
New features (backwards compatible)	MINOR	`1.2.3` -> `1.3.0`
Bug fixes only	PATCH	`1.2.3` -> `1.2.4`

2. Update Version Files

Common files that may need updating:

# Node.js
package.json         # "version": "1.0.0"

# Python
setup.py            # version="1.0.0"
pyproject.toml      # version = "1.0.0"
__version__.py      # __version__ = "1.0.0"

# Other
VERSION             # 1.0.0
version.txt         # 1.0.0

3. Create Tag and Push

# Commit version bump
git add .
git commit -m "chore: bump version to 1.1.0"

# Create tag
git tag -a v1.1.0 -m "Release version 1.1.0"

# Push commit and tag
git push origin main
git push origin v1.1.0

Safety Rules

Action	Risk	Alternative
Modifying pushed tags	Breaks others' references	Create new tag
Force pushing tags	Overwrites history	Delete and recreate
Deleting release tags	Loses version history	Mark as deprecated

Fixing a Bad Tag

# If tag not pushed yet
git tag -d v1.0.0
git tag -a v1.0.0 -m "Corrected release"

# If tag already pushed (coordinate with team)
git tag -d v1.0.0
git push origin :refs/tags/v1.0.0
git tag -a v1.0.0 -m "Corrected release"
git push origin v1.0.0
