Today Google Play Music was updated to version 5.4 bringing in a number of new fixes and features. The most important new feature is perhaps the new My Devices interface, which allows users to be able to manage and deauthorize devices straight from their phone or tablet, instead of having to do it through the desktop version of the service.
Another big update to the service is the ability to pre-cache whole radio stations to listen to offline. The feature, called Keep on device, which was only used for songs, playlists, albums and so on before, is now also useable for radio stations. Keep in mind that there are some exceptions to this and there are some radio stations that you can't listen to offline.
Apart from those updates, users can also now refresh their device which will find any music that was recently added to your library. There is also now a floating Playing bar which now stays on the screen as the user scrolls, as well as a shuffle option that has been added to Listen Now.
A number of bug fixes have also been included in the update, including a fix to a bug that added duplicate Chromecasts to the list on the device.
