Versioning Strategy Semantic Versioning (SemVer) MAJOR.MINOR.PATCH

1.0.0 → 1.0.1 (patch - bug fix) 1.0.1 → 1.1.0 (minor - new feature) 1.1.0 → 2.0.0 (major - breaking change)

Conventional Commits feat: add new feature (minor bump) fix: fix bug (patch bump) perf: performance improvement (patch bump) docs: update docs (no bump) chore: maintenance (no bump)

Best Practices Conventional commits: Standardize commit format Protected branches: Prevent direct pushes to main Automated versioning: Let tools determine versions Changelogs: Auto-generate from commits Git tags: Tag every release Release notes: Include migration guides Dry run: Test releases in staging Output Checklist Changesets or semantic-release configured Versioning strategy documented Changelog generation automated Git tagging automated Release notes template NPM publishing (if package) Docker publishing (if applicable) Protected branch rules
