thanks for the documentation!

however, as i am using RELEASE.md as a checklist (i am really going through that step by step on releases, reading through every step to not forget anything :) - i would prefer to have that shorter and easier - it is currently more steps than in-app-strings and offline-help together.

i suggest to create a dedicated ./scripts/pull-fdroid-metadata.sh with the following content:

git remote add weblate https://translate.codeberg.org/git/delta-chat/android-metadata/  # this prints an error when already added
git fetch weblate
git merge --no-ff weblate/main -m "Merge F-Droid metadata translations from Weblate"  # this prints "Already up to date" when all is in sync

and add that to RELEASE.md at step 3.

for the added "remote": i did not work with multiple remotes yet - "origin" is still the default? wondering if there is sth. to keep in mind ...

Maybe we switch to hosted weblate (#3024) and it will just open PRs from time to time automatically.

yes, maybe that's better. seems reasonable to do what is kind of default for translators. if that works out, we can also consider to move strings.xml there and see how it goes - maybe start with languages that are not present or badly translated on transifex, but that is nothing for the next weeks ;)

but for now, i would also be fine with one more step in RELEASE.md

i think, this is what happens meanwhile eg. at #3145 .
closing this PR for now.

btw, seems also Delta Chat was approved as an open source project; at least i do not see a warning any longer
