Apple on Monday started seeding a second iOS 8.4 beta to developers, bringing more refinements to the company's future update for iPhones, iPads, and iPods.
The new code can be downloaded as an over-the-air update for existing iOS 8.4 users and should soon be available through Apple's iOS Dev Center as well. In release notes, Apple promises bugfixes and miscellaneous other improvements over the first beta, which was released two weeks ago.
The core feature of iOS 8.4 is an overhauled Music app. It sports a number of interface changes, among them gesture controls, global search, and a persistent MiniPlayer allowing playback control from anywhere in the software.
Apple has also issued the first public beta of the software, based on the latest developer release, and a developer seed of Xcode 6.4 beta 2 for app creators. Access to the public iOS 8.4 beta requires signing up for Apple's Beta Software Program.
