10.7.2 is the Product Marketing Version. It's for the consumers. The 11 is the Darwin Kernel version. The letter is a non-public "feature set" or "build train" and is not in any way tied to the dot release of the product marketing version. Why oh why do this people start to define these things when they do not know what they are talking about. There will be stupid people believing that now.
