Yay for updates!

You may have noticed the update to the Blizzard updater that downloads when you start the game. Blizzard poster Drysc tells us what it's all about:

The World of Warcraft Launcher is receiving an update today that will allow it to check your current game version and download the latest patch if one is available, without needing you to log in to the game. For those of you who don't use the Launcher the game will still check as it always has when you log in.
