I have two unRaid systems - one is mostly a media server. The other handles backups and runs Scrypted (which is awesome - I have all of my cameras viewable on Echo Show's now). I updated my Scrypted system. The only problem I ran into was that NUT plugin was not compatible.
I will let it run a while before considering the upgrade of my media server. I won't be using ZFS on it, so no hurry and no major feature I need.
