Your most recently selected pose will now be saved.
Characters will now use the last pose selected using the /changepose emote when standing in place or sitting. Characters will revert back to the selected pose even after another emote is used.
* The delay before the selected pose is active can be adjusted on the Character tab under Control Settings in the Character Configuration interface.
Random pose cycling has been added.
Characters standing idle for extended periods of time can now cycle through pose animations at random. The delay before the initial pose can be set via the Character Configuration interface. Subsequently, poses will cycle every 10 to 30 seconds.
It took me a while to understand what this was saying and where the options were, but eventually I figured it out. Now I have to say that the way they're implemented is rather counter-intuitive.

The delay before your chosen idle animation (see first quote) is controlled by the Idle Animation Delay slider. The Enable Idle Animation actually switches on the function to randomly cycle through alternate idle animations. There is no separate control for how fast these will cycle, it seems to be controlled via the above idle delay slider.

Maybe it's just me, but that seems kind of confusing.
