Hi @hannesa2! Thanks for your contribution! 🙌🏻 Just a comment before the CR:

The calens entry is necessary for this fix, so could you add a new commit (chore: add calens file) including all the changelog information? Please don't forget to read the TEMPLATE.md before adding it. Let us know if you have any doubts and we will help you!

It's fine for me, when you maintain this calens stuff.
Btw, you could have this changelog much easier https://github.com/AppDevNext/AndroidChart/blob/9d7d728f6ef501168736184846889c6ad05a14c3/.github/workflows/Android-CI-release.yml#L59

generate_release_notes: true

Thanks for the suggestion! We will take a look at the yaml file that you mentioned 🤔

NOTE: Calens ≠ Release Notes. Calens is used for the changelog, while release notes are intended for end users

With https://docs.github.com/en/repositories/releasing-projects-on-github/automatically-generated-release-notes (which is the stuff under the hood) you can make categories of pull request, e.g customer-related, then it generates it by categories, and after this, you can easy delete stuff from output.
But why filter content ? This is the main issue for me. Be transparent !
