I got around to finally upgrade our directory server, which is a manually installed instance: zot.factoryfouroh.net. No issues so far, all went well.
I also upgraded one of my test instances, dw-alfa.kane-il.us to YunoHost 4.2.6 (stable) - I love it! You guys are doing a fantastic job with YunoHost, an updated look, lots of new functionality, and the quality of the service stack just feels robust!
I upgraded the YunoHost instance of Hubzilla - it reads 5.6 - 1245. It seems to be working fine, but I am going to wait for a few days before upgrading this node. Leaving the Big Tech plantation is looking better and better by the day, thanks so much for everyone!
