-1. After all tests pass and you have received approval from a [CODEOWNER](./CODEOWNERS), merge the PR into `master`. "Rebase and merge" is preferred in this case. _Never_ squash to `master`.
-1. Pull `master` locally, create a new tag (based on version number from previous steps), and push up. The tag should _only_ be the version number. It _should not_ be prefixed  `v` (i.e. `X.Y.Z`, not `vX.Y.X`).

+1. Open the release draft, review the changelog, assert the assets (vendor) have been added, and publish the release when ready.
 1. Wait for the [_Release wp-saml-auth plugin to wp.org_ action](https://github.com/pantheon-systems/wp-saml-auth/actions/workflows/wordpress-plugin-deploy.yml) to finish deploying to the WordPress.org plugin repository. If all goes well, users with SVN commit access for that plugin will receive an emailed diff of changes.
 1. Check WordPress.org: Ensure that the changes are live on [the plugin repository](https://wordpress.org/plugins/wp-saml-auth/). This may take a few minutes.
