Apple has released the fourth beta of iOS 11.4 to developers. The newest beta comes less than a week after the third beta was seeded out.

Like most minor beta updates, not much is new in terms of big changes. Most of changes come in the form of optimization and bug fixes, which is not that exciting but its still useful. iOS 11 in particular has been dogged by annoying bugs and anything Apple can do to fix that is welcomed.

Some of the updates iOS 11.4 is adding includes iCloud Messages, AirPlay 2, HomePod stereo pairing and (PRODUCT) RED iPhone wallpapers exclusively available for the iPhone 8 and 8 Plus.

Developers can download the fourth beta of iOS 11.4 now. The public beta should roll out in the coming days.
