As promised, Apple released iOS 8.4 on Tuesday ahead of the launch of Apple Music. The update includes support for Apple's new streaming music service along with bug fixes.
Apple adds Apple Music support to iPhone, iPad, iPod touch
Apple Music is Apple's big entry into the streaming music market. It includes the Beats 1 Internet radio station, streaming music stations like iTunes Radio, and the Connect service where artists can interact with their fans.
Apple Music costs US$9.99 a month, or $14.99 for families up to six people. It also includes a free three-month trial.
A very welcome fix in the update addresses the "effective power" bug that crashed iOS devices and Apple Watch whenever you received a text with a specific string of characters.
You can install iOS 8.4 by tapping Settings > General > Software Update on your iPhone, iPad, or iPod touch. Next, tap Update to start the download process. iOS 8.4 is a free update.
