Apple is now in its third series of beta versions for developers, with new versions of macOS 10.15.5, tvOS 13.4.5 and OS 6.2.5 now available for developers.
The latest versions can be purchased from the Apple Developer Center for Developer Beta participants, as well as via a live update for hardware used for beta software. Public beta versions of developer versions are generally released within a few days of their peers and can be purchased from the Apple Beta software program site.
The third cycle, including the renowned iOS 13.5 and iPadOS 13.5, takes over from the versions provided by Apple on April 15. The first batch of versions was released on March 31 for iOS 13.4.5, iPadOS 13.4.5 and tvOS 13.4.5, while the version of OS 6.2.5 appeared on April 1.
The release notes for the versions have not yet provided details on the main changes to the functionality of each operating system, beyond the first support for coronavirus exposure notification in the iOS beta version 13.5 from Wednesday, Apple advising only the usual patches and improvements. Given the version numbering, as well as the relative proximity to WWDC 2020, it is plausible that this is largely a maintenance release.
Alone, the software hooked in iOS 13.5 for exposure notification does nothing by itself and requires an app for the functionality, which is not available at the moment.
Review of previous versions revealed an option for Apple Music subscribers to share what they listen to on Facebook and Instagram.
Appleiphonestop and Apple itself strongly recommend that users do not install beta on “critical” or primary devices, as there is a remote possibility of data loss or other problems. Instead, testers should install beta on secondary or nonessential devices and make sure there are enough backups of important data before the update.
Update: Apple has released a public beta version of iOS 13.5 for testing.
