-## Building and tagging a release (requires write access)
-
-1. Test your changes, merge into `master`.
-2. Checkout `master`.
-3. Bump the version number in [`package.json`](package.json).
-4. Run `./bin/build-release julia-actions/setup-julia` to create a release branch and build a release.
-5. Push the branch (**without tags**) and verify that CI is passing on it.
-6. Run `git push --tags --force` to update the tags.
-7. Create a release for the `vX.Y.Z` tag.

- `1.0` is a version range that will match the highest available Julia version that starts with `1.0`, e.g. `1.0.5`, excluding pre-releases.
- `^1.3.0-rc1` is a **caret** version range that includes pre-releases starting at `rc1`. It matches all versions `≥ 1.3.0-rc1` and `< 2.0.0`.
