 ## Releases
 
 This repo uses _Release Please_ to release packages. Release Please sets up a running PR that tracks all changes in the library, and maintains the versions according to [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/), generated when [PRs are merged](https://github.com/amannn/action-semantic-pull-request), based on the PR title. The semantics of the PR title are enforced by the `lint-pr.yml` workflow. When Release Please's running PR is merged, a new release is created, and the associated artifacts are published.
