iOS developers, another beta update has arrived. 

Apple today released iOS 10.3.3 beta 2, a new update that comes two weeks after the initial iOS 10.3.3 beta release. The update is now available to registered developers in the Apple Developer Center or over the air.

So far, no significant new features have been found inside the iOS 10.3.3 beta releases. Given that it’s an x.x.1 release, it’s likely that iOS 10.3.3 focuses on under-the-hood performance improvements and bug fixes.

Apple hasn’t said when iOS 10.3.3 will be released to the public.

Also being released today is watchOS 3.2.3 beta 2. If you’re a registered iOS developer, you can grab this update, too.
