AppStream backed KAboutData

Volker Krauserequested to merge
work/vkrause/appstream-aboutdata into master

This adds two new features:

  • Fill KAboutData from the applications AppStream data. This avoids some duplicated strings (and thus translation work) and helps to keep in-app and website content in sync. This is even more useful when extending the amount of data included here, as done in e.g. !374 (closed).
  • Add support for release notes to KAboutData, following the AppStream data model. This is meant to feed in-app release notes like https://invent.kde.org/libraries/ktextaddons/-/tree/master/textaddonswidgets/whatsnew. That currently uses in-code release notes rather than AppStream, which means the website and software stores don't benefit from them.

Limitations/future work:

  • This does not follow runtime language changes (but neither does our current usual approach of filling KAboutData).
  • This does support (but does not require) translated release notes, which our i18n tooling, the website and the software store publishing pipelines don't support yet.
