There seem to be little changes of interest to developers (except bug fixes), with the notable exception being eGPU support. Apple’s apparent reversal of their complete disregard of everything that requires a GPU could be a game-changer for developers in the Gaming, Cryptocurrency, VR, 3D, Pro and Video sectors. Now if they’d just update their stone-age OpenGL drivers and start supporting the cross-platform industry standard Vulcan.
One other interesting thing is that ‘iMessage in the Cloud’ was again dropped again just before the final release. Originally scheduled for iOS 11/macOS 10.13, ‘iMessage in the Cloud’ has been present in every OS beta release for the better part of a year now, but was always dropped in any official release. Is this a sign of Apple’s rumoured push of software-quality instead of releasing beta-quality stuff or just a sign that they are even less able to get their act together with anything software-related than in the already poor past few years?
