Some new changes have gone into trunk worth announcing here. They're on the official servers now too.
* (bug 2929) Prevent buildable model and bbox from being too far from each other (glitch building). Thanks F50, gimhael.
With this most things people call "glitch building" are eliminated or severely neutered. Models may be below the bounding box still but the degree is limited to only be so very slightly (within 15 units).
* (bug 4879) Prevent teamchanges for gameplay exploit reasons by enforcing a 30 second wait before you can change again
See
http://tremulous.net/forum/index.php?topic=15012.0* (bug 4684) Don't stop playing a demo when someone presses TAB etc. (Giulio Dignitoso)
Most people who watch a lot of demos already use something that does this.
* Print pause time in seconds instead of ms when unpaused
* Implement a max pause time of 2 minutes in case an admin lags out or something after pausing
http://tremulous.net/forum/index.php?topic=14970.0* Don't display location during intermission
* g_disabled* cvars are used by ui but were not communicated to the client
* Don't let maps set {alien,human}BuildPoints since that's probably not good
* Let maps set temporary variables instead of cvars (for e.g., gravity)
If you want an updated client binary (not required to play) for the demos change or still haven't updated for the userinfo cvars fix (wallwalk etc.), I have some compiled for windows/linux here: (64 bit thanks kevlarman)
