Members of Apple's registered developer program can now get their hands on a second pre-release beta of iOS 9.3.2, a forthcoming maintenance and security update for iPhone and iPad that also restores the ability to use Night Shift while in Low Power Mode. New betas of watchOS 2.2.1 and OS X El Capitan 10.11.5 are also available.
Aside from the tweak to Night Shift, no major changes are expected in iOS 9.3.2, as Apple is likely to hold off on significant new additions to the platform until iOS 10 is likely announced at the Worldwide Developers Conference in June. The new build is identified as 13F61.
The last publicly released iOS update was iOS 9.3.1, issued in late March to fix a Web link crashing bug.
New betas of watchOS 2.2.1 (build 13V420) and OS X El Capitan 10.11.5 (build 15F24b) are also available from Apple's developer portal.
