'Automatically' generate nice changelogs. Still requires manual intervention to decide what is interesting user-facing changes for the changelog and what is not when finishing features/fixes.

But the idea behind it is to run during CI and take all those changes and package them up into a nicely formatted SemVer changelog so that at that moment everything happens automated.

Also nice to combine with a release automation, e.g. goreleaser, which can then take just the new changes to add to each release.
