Registered members of Apple's developer program can now access the second pre-release beta builds of all four of the company's major platforms, with new iOS, watchOS and tvOS builds joining a macOS beta that launched earlier this week.
iOS 11.2.5 beta 2, watchOS 4.2.2 beta 2, and tvOS 11.2.5 beta 2 are all available to download through Apple's developer portal. Public beta builds should be forthcoming as well.
They join a second developer beta of macOS High Sierra 10.13.3, which launched on Monday.
Given that the updates are point-zero-one releases, it's unlikely that major new features are coming to the updates. Instead, Apple usually keeps those minor updates limited to bug fixes and small tweaks.
The first developer betas of iOS 11.2.5, watchOS 4.2.2 and tvOS 11.2.5 debuted less than a week ago. The quick updates between beta releases could be a sign that the software will launch to the public soon.
