Clarification of statement about stateless sytem

[Aaron Konstam <akonstam sbcglobal net>]

In section 2.2.6 of the F10 release notes is the following statement:

Support for keeping a persistent /home with the rest of the system
stateless has been added for Fedora 10.

I don't understand that statement? Could someone explain it, especially
the meaning of the words persistent and stateless in that context.
