## Type of Change

Our release process assumes you are using [Conventional Commit
messages](https://www.conventionalcommits.org/en/v1.0.0/).

The most important prefixes you should have in mind are:

- `_fix_`: which represents bug fixes, and correlates to a SemVer patch.
- `_feat_`: which represents a new feature, and correlates to a SemVer
minor.
- `_feat!_`:, or `fix!:`, `refactor!:`, etc., which represent a breaking
change (indicated by the !) and will result in a major version change.

If you have not included a conventional commit message this can be fixed
on merge.

## Check List

- [ ] New functionality includes tests
- [ ] All tests pass
- [ ] Commit message includes a [Conventional Commit
Message](https://www.conventionalcommits.org/en/v1.0.0)
