The servers were down last night European time for the weekly update. Most notable are the locked cl_yawspeed and cl_pitchspeed for disabling "ninja scripts", the step code changes and the new speedometer command. The full changelog can be found below:

The QUAKE Live Updated Update from September 30th

"We have applied a small update to correct an issue discovered with last night's update. This new update should further address the name change exploit.

In addition to this important fix is included a small client-side option, for those who really like to customize their personal game environment, that allows you to set the length of time weapon impact marks are drawn in the environment. Players who currently have marks enabled (cg_marks 1), can now shorten the length of time impact marks are drawn using cg_impactMarkTime. This value currently defaults to '10000', or 10 secs."
