Greetings,

We’re making a change to a number of CVars in the upcoming Patch 5.4.8 (release date: TBD). UI Add-Ons will be unable to update the following CVars while the player is in combat. Add-On authors, please feel free to use the 5.4.8 PTR testing environment to see if an UI Add-On is compatible with the upcoming patch before it goes live.
