One of the reasons why there is a preview of Android L provided so that, developers can resolve any issues before the official release and that is exactly what they did with their own Dropbox app Carousel.
Here's the official changelog of the update:
- Hide or remove it quickly groups of photos and video in your Carousel
- The automatic backup of photos and videos is optional
- Recipients do not need to have Carousel to view photos and videos shared
- Carousel runs on Android L
Not only Android L then, but other features like backup, sharing and group photo; Carousel can be downloaded for free from the badge below.
