Beta 2 of iOS 13.4.5 & iPadOS 13.4.5 Released for Testing
Apple has released new beta builds of iOS and iPadOS 13.4.5 for users who are enrolled in the beta testing programs for iPhone and iPad.
Both iOS 13.4.5 Beta 2 and iPadOS 13.4.5 beta 2 are available to download now on eligible iPhone, iPad, and iPod touch devices.
Beta testers can find the latest beta release available in Settings > General > Software Update
Separately, tvOS 13.4.5 beta 2 and watchOS 6.2.5 beta 2 are available for testing with Apple TV and Apple Watch, respectively.
MacOS 10.15.5 Catalina beta 2 is not yet available, but likely will arrive soon for Mac beta testers as well.
The new beta builds presumably focus on bug fixes and enhancements, and are not expected to include any major new features or changes to system software.
Apple usually goes through various beta builds before issuing a final version to the public, suggesting that with the release of the second beta the final public release of iOS 13.4.5 and ipadOS 13.4.5 is still some time away.
