 - DietPi-Software | DietPi-RAMlog: When installing/enabling RAMlog, the /var/log mountpoint will be now cleaned before mounting the tmpfs on it, while preserving the existing logs metadata. This resolves a warning on early boot stage and frees the disk space consumed by the disk log before.
 - DietPi-Software | rTorrent: Runs now as user "rtorrent" and creates files as group "dietpi" with 775/664 permissions. Enabled Buster support and enhanced config file handling on reinstall: https://github.com/MichaIng/DietPi/pull/2633
 - DietPi-Software | Plex Media Server: Now installs the latest version automatically (currently 1.15) which as well includes official ARM binaries. Many thanks to @WolfganP for informing us about this new release: https://github.com/MichaIng/DietPi/issues/2553
