Heads up to all #Riot users: with the recent attack on @matrix' infrastructure, it's possible that Riot's Google Play version got compromised. This doesn't affect Riot's F-Droid version. Just as Riot started to do now, F-Droid has always signed all its apps on an inaccessible, offline machine. For more information, see https://riot.im/reinstall
To avoid maintenance overhead, however, it's likely to happen that F-Droid users must also change the app in near future. Still, there's no need to act now.
