Apple has restarted the beta cycle once again, offering developer testers the first beta builds of iOS 13.4, iPadOS 13.4, tvOS 13.4, watchOS 6.2, and macOS 10.15.4.
The newest builds can be downloaded via the Apple Developer Center for those enrolled into the test program, or via an over-the-air update on devices running the beta software. Public betas typically arrive within a few days of the developer versions, via the Apple Beta Software Program website.
The start of the latest set of betas appears eight days after Apple closed out the previous collection, with the release of iOS 13.3.1, iPadOS 13.3.1, tvOS 13.3.1, watchOS 6.1.2, and macOS 10.15.3 to the public on January 28. The last cycle of betas took three iterations, and ran through December and January.
At the time of publication, it is unclear exactly what the betas contain in terms of new features, if anything. The naming of the beta versions suggests it to include some major changes and improvements, rather than acting as a more incremental release.
AppleInsider, and Apple itself, strongly recommend users don't install the betas on primary devices or hardware they deem as "mission critical" at all, as there is the highly remote possibility of data loss or other issues. Testers should instead install betas onto secondary or non-essential devices as a safer alternative, and to always make sure there are sufficient backups of important data before updating.
