iOS 13.4 GM & iPadOS 13.4 GM Released for Testing, Along with MacOS Catalina 10.15.4 Beta 6
Apple has released the GM (Golden Master) versions of iOS 13.4 and iPadOS 13.4 to users enrolled in the beta testing programs, carrying the build number of 17E255. A GM build is typically the final version of a developer build that then gets released to the general public.
Separately, Apple released macOS Catalina 10.15.4 beta 6, along with watchOS 6.2 GM, and a new beta of tvOS 13.4.
iOS 13.4 GM and iPadOS 13.4 GM includes bug fixes and security enhancements, and several changes and new features are also included. The Mail app has received a minor redesign to the toolbar, perhaps to help prevent accidental deletion of emails. Additionally, iCloud Drive Folder Sharing is included, which allows users to share folders in iCloud Drive between other people, similar to the cloud sharing functions of DropBox, Box, Google Drive, and OneDrive. iOS 13.4 GM and iPadOS 13.4 GM also include new Memoji features.
Unique to iPadOS 13.4 GM is further support for using a mouse or trackpad with iPad, with the new build including some new mouse and trackpad features introduced with the freshly launched iPad Pro and Magic Keyboard with Trackpad for that device.
MacOS Catalina 10.15.4 beta 6 adds Screen Time Communication Limits capabilities, a new Accessibility feature that allows control of the cursor through head gestures, and presumably includes support for iCloud Folder Sharing as well. The beta seems to primarily focus on bug fixes and other minor system enhancements, however.
All users who are enrolled in the beta testing programs for Apple system software can download the latest GM and beta builds through their respective software update mechanisms on an enrolled device.
iOS 13.4 GM and iPadOS 13.4 GM can be downloaded through the Settings app > Software Update feature.
macOS Catalina 10.15.4 beta 6 is available from System Preferences > Software Update.
WatchOS 6.2 GM and tvOS 13.4 beta can be downloaded their settings app software update functions as well.
With iOS 13.4 GM and iPadOS 13.4 GM now available, the final public versions will likely release to everyone in the very near future.
Apple typically releases several beta versions before releasing a final version to to the general public, which also suggests macOS Catalina 10.15.6 is nearing completion, as are watchOS 6.2 and tvOS 13.4.
