After a break for the holidays, Apple has returned to the beta-testing grindstone, providing developers with the second trial builds of iOS 13.3.1, iPadOS 13.3.1, watchOS 6.1.2, tvOS 13.3.1, and macOS 10.15.3.
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 latest builds follow the first batch, which were issued on December 17. Prior to that, Apple completed testing of iOS 13.3, iPadOS 13.3, watchOS 6.1.1, and tvOS 13.3 on December 10, after four rounds of betas.
It is unknown what Apple is changing or updating in any of the betas, as the support documents for each version state there are "no release notes" for the software update. The incremental nature of each strongly suggests the betas are for performance improvements and minor changes, rather than relating to the addition or alteration of features.
Both AppleInsider and Apple itself strongly recommend users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
