I tried to update Friendica to the latest stable today, but the @YunoHost package for Friendica pulled the development version of Friendica instead of the stable one. I reported it here github.com/YunoHost-Apps/frien… - there is a mistake somewhere....but we can't afford to run the dev branch for our 900 or so users. I will try again later on when this is fixed. For now it is all good, I have restored a server snapshot.
