okay, we started the upgrade from 0.17.1 to 0.18.7. this is horrible. 1) all IP assignments shuffled. it would have been really nice-to-know info in advance as this literally breaks our setup completely. 2) old external clients stay in the UI with no way to remove them. this really just hurts my OCD, but it hurts bad. EDIT: Old hack still worked, I could create new ext client with same name, and then remove it. That removes old external client with same name also. 3) some netclients seem to have hickups at least in Ubuntu and Debian: [netclient] 2023-04-26 06:22:52 failed to pull SIGHUP failed -- os: process already finished. reboot fixed this behaviour. 4) all the old nodes stay in the ACL table as nodes without names, kinda like old external clients. there is however no way to remove them. this is absolutely horrible. 5) networks are no longer editable, which seems like a bad feature. So, upgrade is now complete and we live to fight another day. Would be nice however to get fix to ACL table
