Differences between 801 and 802?

I know odd question to come up in 2009, but our schools material is dated back from the old exam. I do got a newer Cisco book myself(sybex) but after I'm done I should pay particular attention to material not covered in school.

aside from igrp and isdn being gone, and the addition of sdm, switch security, wireless, and ipv6

What else has changed?
