iOS 4.2

Apple has released the second beta build of iOS 4.2 to its development community, bringing the next generation of the iPhone/iPad/iPod touch/AppleTV operating system one step closer to its November rollout. New additions to this build were not immediately clear at the time of this writing, although Engadget notes that "it's already so much less buggy than Beta 1 we're weeping with joy."

As you may recall from previous coverage, iOS 4.2 brings the most benefits to iPad owners, as it is the first build to bring version 4.x to that device. There are a few nice additions for iPhone owners, though, including AirPrint wireless printing and AirPlay wireless multimedia streaming.

iOS devs, please feel free to note any changes you've observed in the comments.
