Apple today released the first beta version for iOS 13.4.5 developers, following the public launch of iOS 13.4 and iPadOS 13.4 last week.
In this update, Apple only focused on bug fixes and performance improvements, making this clear in the update notes.
In addition to iOS 13.4.5, versions of iPadOS 13.4.5, macOS Catalina 10.15.5 and tvOS 13.4.5 were also made available. So far no new update has been found for the Apple Watch system.
For the time being no more differences were detected in the new versions of the system, but within days new features should appear, as soon as the programmers have greater access to the new operating systems.
