Versioning Guide

Semantic Versioning

CaddyProxyManager+ follows Semantic Versioning 2.0.0:

• MAJOR.MINOR.PATCH (e.g., 1.2.3)
  • MAJOR: Incompatible API changes
  • MINOR: New functionality (backward compatible)
  • PATCH: Bug fixes (backward compatible)

Pre-release Identifiers

• alpha: Early development, unstable
• beta: Feature complete, testing phase
• rc (release candidate): Final testing before release

Example: 0.1.0-alpha, 1.0.0-beta.1, 2.0.0-rc.2

Creating a Release

Automated Release Process

1. Update version in .version file:

   echo "1.0.0" > .version
   

2. Commit version bump:

   git add .version
   git commit -m "chore: bump version to 1.0.0"
   

3. Create and push tag:

   git tag -a v1.0.0 -m "Release v1.0.0"
   git push origin v1.0.0
   

4. GitHub Actions automatically:

   • Creates GitHub Release with changelog
   • Builds multi-arch Docker images (amd64, arm64)
   • Publishes to GitHub Container Registry with tags:
     • v1.0.0 (exact version)
     • 1.0 (minor version)
     • 1 (major version)
     • latest (for non-prerelease on main branch)

Available Tags

• latest: Latest stable release (main branch)
• development: Latest development build (development branch)
• v1.2.3: Specific version tag

• main-<sha>: Commit-specific build from main

• fix: Bug fixes
• docs: Documentation changes
• chore: Maintenance tasks
• refactor: Code refactoring
• test: Test updates
• ci: CI/CD changes
