--- failure enum_marked_non_exhaustive: enum marked #[non_exhaustive] ---

Description:

#868 re-configured the changelog generation to be based on the new sub-crate instead of the full repo.

Annoyingly, this causes git-cliff to ignore the previous commits where the project was at the root of the repo.
Here is a copy from the last changelog commit before that change. We should re-add this before merging the release PR.

## 0.2.1 (2024-03-06)

### Documentation

- HUGR spec copyediting ([#843](https://github.com/CQCL/hugr/pull/843))

- Add note on serialized hugr node order ([#849](https://github.com/CQCL/hugr/pull/849))

### Features

- Arbitrary types in the yaml extension definition ([#839](https://github.com/CQCL/hugr/pull/839))

- Don't include empty type args in Display ([#857](https://github.com/CQCL/hugr/pull/857))
- Mermaid renderer for hugrs ([#852](https://github.com/CQCL/hugr/pull/852))
- Add impl TryFrom<&OpType> for ops::* ([#856](https://github.com/CQCL/hugr/pull/856))
