## Add a release note
`doc/manual/rl-next` contains release notes entries for all unreleased changes.
User-visible changes should come with a release note.
### Add an entry
Here's what a complete entry looks like. The file name is not incorporated in the document.
```
synopsis: Basically a title
issues: #1234
prs: #1238
description: {
Here's one or more paragraphs that describe the change.
- It's markdown
- Add references to the manual using @docroot@
}
```
Significant changes should add the following header, which moves them to the top.
```
significance: significant
```
<!-- Keep an eye on https://codeberg.org/fgaz/changelog-d/issues/1 -->
See also the [format documentation](https://github.com/haskell/cabal/blob/master/CONTRIBUTING.md#changelog).
### Build process
Releases have a precomputed `rl-MAJOR.MINOR.md`, and no `rl-next.md`.
Set `buildUnreleasedNotes = true;` in `flake.nix` to build the release notes on the fly.
