Earlier today, Apple announced new iPad Pro models, and that iPadOS 13.4 is going to be released next week with trackpad support. If you're a developer, you can get your hands on the software update early though, as the GM seeds for iOS 13.4, iPadOS 13.4, and watchOS 6.2 are now available.
Obviously, the big new feature in iPadOS 13.4 is trackpad support, and that includes gestures and more. But there's also support for iCloud Drive folder sharing, and better controls over viewing and editing permissions.
You'll find new Memoji stickers, and in the Mail app, more visible controls for delete, move, reply to, and compose buttons. One thing that's more significant is support for universal purchases between iOS, macOS, and tvOS. And of course, there are also a range of fixes in this minor update.
watchOS 6.2 is even more minor. The ECG app is now available in Chile, New Zealand, and Turkey, and those countries can now get irregular heart rhythm notifications. This update also adds the ability for developers to add in-app purchases to Apple Watch apps.
Presumably, GM seeds for tvOS 13.4 and macOS 10.15.4 should be following soon.
