Yesterday there was a little Quake Live Update going on.
Sync Error mentioned that these changes do not reflect the bulk of what id is been working on lately. It was important to release a fix to a recently discovered game exploit, and work progresses in other areas for an upcoming update.

Here are the Updates which where made:
* Fixed demo playback for demos with long file names.
* Fixed the accuracy menu to update properly in Clan Arena.
* Fixed the players-left-alive count to update properly in Clan Arena when an alive player disconnects.
* Fixed banned players' profile pages to once again report the status of their suspension.
* Fixed issues that had arose with the Match tool-tips.
* Changed 'cg_gibs 0' to now entirely disable the death spark effects.
* Changed Cobalt Station - qzdm16's max player limit to 8 players in CTF mode.
