Apple issues fourth developer betas of iOS 11.2.5, watchOS 4.2.2, tvOS 11.2.5, and High Sierra 10.13.3

One week after the last batch, registered members of Apple's developer program can now access the fourth pre-release beta builds of operating systems for the iPhone, iPad, Mac, Apple TV, and Apple Watch.

The updates are "sub-point" releases, so it remains unlikely that major new features are coming to the updates. Apple usually keeps small version increments limited to bug fixes and small tweaks, with the most likely addition to the new betas being fixes for the "Meltdown" and "Spectre" vulnerabilities.

The release notes remain nearly empty, and contain no testing notes.

The new versions are all available to download through Apple's developer portal. Public beta builds should be forthcoming as well.

On Monday, Apple released iOS 11.2.2 and a supplementary macOS High Sierra 10.13.2 security patch for the aforementioned "Meltdown" and "Spectre" issues.
