From the mouth of Kirby:
Ok here are the new things that have been added, at least that I remember.

-Survival Mode
-New checks to prevent hosts from abusing power.
-Hosts don't have boot anymore(well in the very next update)
-Definition of Guarding is on the browser in-game.
-Admins and GMs have an Announce verb.
-Emote is finally in-game.
-New modes may be coming soon including:
---Gravity, some new custom maps may have gravity.
---Unnamed, better description in the suggestions topic.
---New Modes that players suggest in the suggestions topic.(none yet)
-Fixed more bugs...as always with everything new added into the game there are going to be bugs, sorry for this, but the players are the only real way to test for bugs.
