The new features in the Photos section are pretty impressive. The app now features "non-destructive cloud photo editing" which will allow you to start editing a photo on one device and continue the edits on a different device if you want, and revert any changes whenever you want. The other big addition is in the editing
On the organization side of things, there is a new "All" view to see every photo you have, and make it easy to sort through them by date. And, there is also a new notification when you go to delete a device saying that there is now a "trash" built in so your photos won't be deleted instantly. Instead, your photos will be moved to the trash and deleted after 60 days.
The rollout of the update has begun, so it may be a bit before you see it, but it is on the way. And, if you're really impatient, there's an APK download option at the source.
