Apple this morning has seeded fourth betas of iOS 9.3.2 (build 13F68), tvOS 9.2.1 (build 13Y772) and OS X El Capitan 10.11.5 (build 15F31a) to developers for testing.
The release for developers comes exactly one week after iOS 9.3.2 beta 3 came out. No word on what’s new yet, but stay tuned. The second beta of iOS 9.3.2 brought back the ability to enable Night Shift while in Low Power Mode. The next beta for watchOS should be out shortly as well.
