A week after completing the final beta testing cycle, Apple relaunched the process and released new beta versions for iOS 13.4.5, iPadOS 13.4.5, tvOS 13.4.5 and macOS Catalina 10.15.5.
The latest versions can be downloaded by developers in the Apple Developer Center’s beta testing schedule or as a live hardware update using previous beta versions. A public beta is expected soon and will be available on the Apple Beta program website.
The latest beta series for iOS 13.4, iPadOS 13.4, tvOS 13.4 and macOS 10.15.4 was released on March 18 and was the sixth round of testing in this iteration. Apple released iOS 13.4, iPadOS 13.4, OS 6.2, tvOS 13.4 and macOS 10.15.4 on March 24.
At the time of publication, the content of each beta is virtually unknown, with release notes recommending “fixes and improvements”.
In addition, beta numbering is very unusual. With the exception of macOS, other betas must add the suffix .1 to the version numbers for typical beta revisions, making version 13.4.1 of iOS, iPadOS and tvOS beta. At the moment, it is not clear why Apple chose to make such a huge leap in version numbers.
Appleiphonestop and Apple strongly recommend that users do not install beta on “critical” or primary devices, as there is a remote risk of data loss or other problems. Instead, testers should install the beta version on secondary or non-essential devices and ensure that there is sufficient backups of important data before upgrading.
