I'm having the same issue as @gviliunas. Everything seemed good with the upgrade, no issues at all. When trying to add a zwave device it looks like its adding it but no devices show up in the tree. I'm using a ZEN32 Scene Controller as a test device. I'm guessing its something to do with security changes. I was never asked to or see a way to put the device code in and it has S2 security.
