Finally, the most welcome change for me and likely others -- speed. Instagram has been updated to allow for faster, endless scrolling and overall browsing of the app has picked up the pace. Users should notice less jerkiness in the app and images loading relatively faster. Instagram has dropped a new video highlighting the changes; you'll find it down below if you're looking for a walkthrough. Otherwise, go ahead and fire up the Google Play Store and get to downloading Instagram 3.0.
