Crusader Kings II v1.09 Patch

Also available via in-game autoupdater
Paradox Interactive today issued a new patch for Crusader Kings II, adding a 'Grant Independence' diplomatic interaction as well as more mercenary bands: Finns, Lapps, Abyssinians, Nubians, Lithuanians, Scots, Irish and Alans. Titles can now automatically change name depending on the culture of their top liege, and save file transfer now works on Mac.
A playable demo can be found here.
