📝 Walkthrough

Walkthrough

Three GitHub Actions workflows are updated: a new PR Title Check workflow validates conventional commit formatting in pull request titles, a new Release Please workflow automates release management and version bumping on main branch pushes, and the existing release workflow removes GitHub release artifact publishing steps while retaining PyPI publication.

Changes

Cohort / File(s)	Summary
New PR validation workflow \.github/workflows/pr-title\.yml	Adds GitHub Actions workflow that enforces conventional commit style in PR titles using amannn/action-semantic-pull-request. Allows types: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert. Requires non-empty subject description.
New release automation workflow \.github/workflows/release-please\.yml	Adds GitHub Actions workflow using googleapis/release-please-action to automate release creation and versioning. Triggers on main branch pushes, bumps patch versions for minor/pre-major releases, and manages xarray_plotly package releases.
Simplified release workflow \.github/workflows/release\.yml	Removes GitHub release step and associated permissions (contents: write). Streamlines workflow to only publish artifacts to PyPI, removing GitHub release artifact creation logic.

Poem

🐰 New workflows hop into place,
PR titles now keep proper pace,
Release Please hops to the main,
While PyPI gets the gain,
GitHub releases fade away—
Cleaner pipelines save the day! ✨
