Addon coders have to keep up with the times. Blizzard dishes out new changes like there's no tomorrow, and gladly it doesn't forget to update its mini developer kit for the World of Warcraft addon authors. Macro and UI community manager Slouken fired a broadside update at the World of Warcraft Forums, stating that the Interface AddOn Kit has been made compatible for patch 2.3.

And now that patch 2.3 is currently running on the Public Test Realms, this gives authors a chance to readjust their UI addons where necessary and play-test their builds before going to final or release versions.

First time addon coders might have to browse around the UI & Macros Forum before attempting anything drastic. A simple rearrangement of the interface would sound like a good start, but always remember to run the kit from the main installation directory of World of Warcraft.

Remember, it's not supposed to be run from the PTR directory (character files and accounts get mirrored there), but the main installation directory of World of Warcraft. Make the needed changes there, then run the addon in the PTR client for testing. Easier said than done.
