Generating Changelog
--------------------

Install dependencies

```sh
$ npm install -g conventional-changelog-cli
$ cd rust-multihash
$ conventional-changelog --preset conventionalcommits
```

Add the output of that to `CHANGELOG.md`. Write a human-centric summary of changes and add migration instructions for breaking changes if needed.

Update the linked output to reference the new version, which conventional-changelog doesn't know about:

```md
# []https://github.com/multiformats/rust-multihash/compare/v0.17.0...v (2022-12-06)
```
becomes:
```md
# [v0.18.0]https://github.com/multiformats/rust-multihash/compare/v0.17.0...v0.18.0 (2022-12-06)
```

Create a pull request with the changelog changes and the correct version bumps to the crates.
