Wordpress server compromised

Long story short: If you downloaded WordPress 2.1.1 within the past 3-4 days, your files may include a security exploit that was added by a cracker, and you should upgrade all of your files to 2.1.2 immediately.

Long explanation...

No Good. Circle with da slash. I have a few wordpress installs. Even though they are not a few days old... I upgraded anyway. I suggest everyone running wordpress to do the same. I'm just wondering if MU was affected. I guess we will find out soon enough.
