Thanks for this PR 💯 One small thing, we need to kinda parse the readme to add new version to the top of the readme (before first ##). See this example changelog: https://github.com/unjs/changelogen/blob/main/CHANGELOG.md

Do you think we should read the new version from package.json and then include it in the changelog?

[pi0]

I think we can introduce the version bump feature to package.json in next iteration.

[Intevel]

Are you working on it?

[pi0]

No but plan to. With this pr, you can use to prop as version. It works on versioned HEAD.

@pi0 Any updates on the version bump feature?

Hi @Intevel. Sorry it took long to be back on this. I've pushed few changes to this feature and preparing for next major version. We by default will update CHANGELOG.md and (preprend) the latest version in entry. I've also added new option of --output to specify changelog file. Using changelogen --no-output it will do as before behavior.

Until supporting --bump, the title entry is config.to which is latest ref.
