Patch day today, hurray!
It looks like there are several UI files that have been updated that will affect almost all interfaces.
I will be going threw each one to ensure they will all work. Please be patient as this may take some time.
You might have to use the Default UI temporarily (shudder) but for the most part you should just get an error about your XML files are not compatible for now.
In other news, I am trying to get this website updated to the new theme so you may experience some lag.
I will keep you all posted on the progress.
