"Unfortunately"
Halelen is right - the UI still works w/o major problems, even w/o any error message.
The changes SOE made with last patch didn't affect any Redux specific files.
But ... with the upcoming expansion there will be changes. E.g. buff and extented target windows increase in numbers of slots.
There will also be changes in the way loot is handled: you can pre-define the loot in categories, e.g. "want this so bad", "that's ok" or "eww, bug someone else with that" (ok, not exactly those categories but you get the idea).
But I'm sure you've already stumbled across some announcements about that, there will be some more features.
