Well, that’s a wrap. Beta time.
This release will be the last release to support iOS 6.x and earlier (it may also drop iOS 5.1 support, depending on how the tools handle things). The next release will be iOS 7 and later only. I am reluctant to drop the older support, but the installed base stats just do not justify keeping around the old code. There was a lot of “if iOS7 do X; otherwise do Y” that had to go in to the last few releases to play nicely with all the releases. It is time to clean that stuff up and migrate to some of the new APIs.
