Instagram’s first major update after iOS 7 doesn’t reimagine the app but brings edge-to-edge photos:

In this update you will find that we’ve increased the size of photos and videos in your feed so that they expand to the edges of your screen. We’re also happy to say that increased size means increased resolution, so photos and videos will be clearer and more vibrant than ever.

Not surprising considering what Facebook did, and what other big players opted for. I would love to know if Instagram saw usage of filters in the app decrease after the release of iOS 7 because of Apple’s new Camera app.
