"Today's update is most notably to address the request and concerns of players who have expressed interest in playing with specific team sizes in team gametypes, such as the ability to play 2v2 Clan Arena, 2v2 Team Deathmatch or 4v4 CTF. Now, up to 16 players may join any game server and the active teamsize will determine how many of those players may participate in the match. This allows you, the players, to decide what you like to play (and more room for spectators to fill in the gaps when players drop)!
While everyone is having fun trying out the new teamsize options, you'll notice that we now display a teammate's health and armor status when you hover your crosshair over them so that you may easily identify which teammates need additional health, armor, or assistance. So no more excuses! Be sure to leave that armor for your team's flag carrier who so badly needs it!"
At the very least this is a good sign that iD Software still cares for a product after it comes out of the beta phase. Quake III Arena has made me happy for many moons and seeing it be modified and put out to the public for free makes me even happier.
If you like first person shooters go give this one a shot! Installing the game and getting it running is pretty self explanitory, iD went to great lengths to make this very accessible so check out the FAQ if you have any questions.
