Apple's annual developer conference in San Francisco.
Apple Finally Updates OS X Lion on Mac App Store to 10.7.1
The update should mean that users newly purchasing OS X Lion will receive 10.7.1 directly rather than having to install the base 10.7.0 version and then update to 10.7.1.
With previous major releases of Mac OS X released on disc, Apple has only rarely updated its retail packaging to include more up-to-date versions of the operating systems. For example, Apple's original Mac OS X Snow Leopard discs were eventually supplanted by discs shipping with Mac OS X 10.6.3, but work continued on Snow Leopard after that time, topping out at version 10.6.8.
