New World of Warcraft patch, must exit Battle.net

There is a new build tonight that Blizzard just pushed up to the servers. It requires a very small patch, and as of right now if you haven't shut down your Battle.net Desktop Client, you're going to get an "incompatible version" error without being prompted to patch the game.

To solve this you'll need to fully exit the Battle.net client and restart it. The easiest way to exit the client, from Windows, is to right click on the tray icon and select "Exit." Once you open the client back up WoW will patch itself to version 19116 (down from 19227, interestingly), and you'll be back in business.
