The LOS were all renumbered.
The new system is a huge improvement, but I was trying to use a Dec '05 Shweser. It was far too confusing going back and forth, so I bought an '06 set.
Also the CFA introduced new packaging for the readings. Instead of buying nine texts, you get four books with the required chapter readings only. It's more affordable, but you can't do any additional reading (if you need to go back to chapter 1 to figure something out).
In ethics they introduced corporate governance and reduced the GIPS reading substantially.
