We haven't yet seen the portables in the new range, however Apple proposes already an update that is intended to them. It will be available via the software update, or from their site:
http://www.apple.com/support/downloads/macbookmacbookprosoftwareupdate12.html
It fixes several bugs and improves the compatibility of MacBook/Macbook Pro 2008 with external screens.
