The World of Warcraft 1.4 patch was released.
Update: Turns out most of the addons still work. That leaves the modification, which breaks because of the updated weapon enchantment stuff.
So grab the new version to fix it.

Update: I've upgraded the XP Monitor.
First, the XP information popup has been moved so it no longer appears over your first party member. Secondly, an XP Rate monitor has been added over your character. You can toggle this on or off using the /xprate command. When toggled on/off, you reset the rate information. It updates every minute. As before, you can force the popup to redisplay by using the /xpmon command.
