Apple has today released the Golden Master (GM) version of tvOS 13 and also
iOS 13.1 beta 4 IPSW restore images for iPhone 11 and iPhone 11 Pro to
developers. This comes after Apple announced that it will release iOS 13.1,
iPadOS 13 and the new tvOS 13 for everyone by early next week.
那今天iphone 11发行的时候顺便公布 13.1不是更好？
13那什么烂东西～
13.1再早几天公布啦！
