Apple makes available fourth developer betas of iOS 11.1, watchOS 4.1

The new software and accompanying build numbers are as follows:

• watchOS 4.1 beta 15R846
• iOS 11.1 beta 15B92

Apple's iOS 11.1 beta 4 also includes the return of the 3D Touch multitasking app switcher, added with beta 2. The fourth beta of watchOS 4.1 does not appear to add anything else, after an earlier version of the beta introduced support for streaming radio stations, including Beats1, over LTE.

A number of features were absent from the public release of iOS 11, including AirPlay 2 and Apple Pay Cash.

Apple's iOS 11.1 is likely to arrive around the time that the iPhone X, ships to customers on Nov. 3.

iOS 11 itself was quickly patched with two minor releases, fixing glaring bugs. It is not clear at this point if the bug fixes introduced in iOS 11.0.3 have been rolled into the latest iOS 11.1 beta — but the issues fixed in iOS 11.0.1 and iOS 11.0.2 have.

The previous developer's betas of iOS 11.1 and watchOS 4.1 were released on Monday.
