Releasing

do tests
update translations using tx pull -a -af (as extra merge request or branch for the case it does not build correctly)
update the version name and version code of the app
update the changelog at app/src/main/play/en-GB/whatsnew
create a tag/ release in GitHub with an changelog; The tag name should be the version number
F-Droid picks up the release by the tag; additonally, the tag triggers a CI build which uploads the generated APK to Google Play
