new variables in latest release

I'm upgrading our office from ss2 to ss3 update 2 and I was unable to find a list of what variables have been change or added in the preferences and configs.  Previous releases always had a list for the admins so you could know what needed to be set in the new workspaces.  I did see that they brought back the deployment packaging after many years of asking for it.  Problem is our office has downsized to the point where it's no longer really needed.

Anyhow, anyone know where I can find these variables?

Thanks!
