There's Epic Level and some Planes information included in this as well....
The Epic information is just notes about progession, progession for the base classes, and feats. No information on epic progression for the included Prestige Classes, unless that's in their own section, haven't looked.
The Planes section gives out information about what a plane is, all the planar traits (yeay!) and descriptions of the Ethereal, Astral, Shadow, and Elemental/Energy planes.
There's also a short blurb on Monster Feats, and Monsters as Characters.
No Dieties & Demigods in here, though.
