Apple on Thursday pushed out an update for its Apple Store iOS client, bringing the app to version 3.7. The update brings about new 3D Touch features on compatible devices, and makes the app available in new countries.
As for 3D Touch support, iPhone 6s users have long been able to utilize Quick Actions on the app icon, but now the Apple Store app supports Peek and Pop. So force-pressing on a link within the app now opens up previews.
