Maps - The new Maps design has rolled out in the San Francisco Bay Area on devices running the latest iOS 12 beta.
Voice Memos - The Voice Memos app has an updated iPad interface.
Share My Location - Location sharing details have been moved from the Privacy section of the Settings app to a new more prominent location in a user's profile right near iCloud settings.
iPad Notifications - There's an option to clear all notifications on the iPad when long pressing on the X at the top of the list of notifications.
Photos - The list of Media Types in the albums section of the Photos app has been cleaned up a bit and no longer lists categories if you have no photos of that type. For example, if you have no time-lapse photos, the time-lapse media type is not included in the list.
Haptic Feedback - On devices with a Home button and haptic feedback, the Home button no longer buzzes every time the iPhone is unlocked. This was an issue on the iPhone 6s and iPhone 7.
