In the Apple's iOS beta 3, we were introduced to a new iCloud Drive feature, an option to disable QuickType, time indicators for Recently Deleted pics, and a way to keep "self-destructing" media.
The newest version of iOS 8 beta is now out. Almost three weeks ago, in the iOS 8 beta 2 release, we saw podcast integration, full-screen caller ID, new assistive touch toggles, and a "disable all" button for app notifications, among other things.
