UPDATE: All QuakeCon 2006 Quake 4 tournaments will be using the 1.2 Point Release due to the limited amount of time available for players to adjust to the new gameplay changes, however, all BYOC servers will be running the 1.3 Point Release, so it is suggested that everyone patch to 1.3 except for those who may wish to keep a separate 1.2 copy for use of practicing prior and during the tournament.

We are also excited to introduce some brand new elements to Quake 4:

The 1.3 update affects pure server and protocol consistency. Therefore, players who update to 1.3 from ANY previous version will only be able to connect and play against other 1.3 users.
Save games created on any previous version of the game will not be compatible with the 1.3 update.
