As expected, Apple has released a third beta of iOS 9 to developers, adding full support for Apple Music, which debuted last week with the release of iOS 8.4.

Featuring a build number of 13A4293f, the third iOS 9 beta also includes a number of under-the-hood improvements from the second beta, focusing on improving the stability and reliability of the new features in the operating system.
A new watchOS beta with a build number of 13S5293f has also been posted, which can be installed via a configuration profile that requires the corresponding iOS 9 beta to be installed.
