release-plz

Release-plz helps you release your Rust packages by automating:

• CHANGELOG generation (with git-cliff).
• Creation of GitHub/Gitea releases.
• Publishing to a cargo registry (crates.io by default).
• Version bumps in Cargo.toml.

Release-plz updates your packages with a release Pull Request based on:

• Your git history, following Conventional commits.
• API breaking changes (detected by cargo-semver-checks).

🤔 What's a Release PR?

Release-plz maintains Release PRs, keeping them up-to-date as you merge additional commits. When you're ready to create a release, simply merge the release PR.

When you merge the Release PR (or when you edit the Cargo.toml versions by yourself), release-plz:

• Creates a git tag named <package_name>-v<version> (e.g. tokio-v1.8.1).
• Publishes the package to the cargo registry by running cargo publish.
• Publishes a GitHub/Gitea release based on the git tag.

📽️ RustLab 23 talk

In RustLab 23, I showed how release-plz simplifies releasing Rust packages, why I created it, and what lessons I learned:

🌓 Similar projects

• release-please: release-plz is inspired by release-please, but instead of determining the next versions based on git tags, release-plz compares local packages with the ones published in the cargo registry. Plus, release-plz doesn't need any configuration and is optimized for Rust projects.
• cargo-smart-release: Fearlessly release workspace crates and with beautiful semi-handcrafted changelogs.
