Quake 4 v1.1

Quake 4 v1.1 final has been released. This new Quake 4 release for both Windows and Linux feature several client enhancements -- in addition to the SDK for mod developers. Some of the improvements include a multitude of changes, and below is id Software's official notice.

The QUAKE 4 1.1 Point Release update is now available. This highly anticipated patch addresses a number of issues throughout both single and multiplayer, with a heavy and attentive focus on improving the multiplayer experience. Such improvements include: a fixed pure server system, a new AddonPak autodownloading system, voice chat in multiplayer, a forcemodel option, brightskins, smooth stairjumping, a one-minute warning for tournament matches, Hyper-Threading Technology and Dual Core support as well as a ton of multiplayer specific fixes which have been requested by the community and discovered during our own gameplay.
This update also includes 4 new professionally made multiplayer maps - free for your fragging pleasure. There are 2 new DM maps and 2 new CTF maps, including a CTF version of the popular "The Edge" map. In addition to these 4 maps, we've also included the free QUAKEMAS map pack that we released in December. Please see below for screenshots of the new maps.
This update will bring any previous version of the game completely up to date, however it will affect pure server and protocol consistency. Therefore, players who update to 1.1 will only be able to play multiplayer against other 1.1 users, and save games and demos created on previous versions of the game will not be compatible with the 1.1 update.

As id Software has been known for, they continue to provide their Windows and Linux binaries with simultaneous releases. The Windows v1.1 patch measures in at 117MB while the Linux one is 114MB. As of writing the id Zerowing server hasn't been updated with this new official update, however, from the id Software website are available downloads.
