Eh, not really. They stuck a bit in the introductory paragraph saying that the white paper is also about Secure Boot, but everything else seems to be entirely tailored to TCG/TPM implementations.
Seems like mentioning SB was really last minute and not particularly well thought out.
The main changes are actually adding reference to secure boot, the section on complete control by device owners, the section on Freedom to Decide and a couple of other things.
Overall, I think it's quite considered. It has been brewing for quite a long period of time (it was hoped that this would be published over a year ago when the Secure Boot problems were just beginning)
