Releasing New Versions

Use the included version bump script to release new versions:

# Preview what will happen
python bump_version.py patch --dry-run

# Bump patch version (0.1.2 -> 0.1.3) and deploy
python bump_version.py patch

# Bump minor version (0.1.2 -> 0.2.0) and deploy
python bump_version.py minor

# Bump major version (0.1.2 -> 1.0.0) and deploy
python bump_version.py major

The script will:

1. Update the version in pyproject.toml
2. Commit the version change
3. Create a git tag (e.g., v0.1.3)
4. Push the tag to trigger GitHub Actions deployment to PyPI

Requirements:

• Clean git working directory (no uncommitted changes)
• Push access to the repository
