Instagram is a great way to share over-emojied pictures of fireworks with friends, but for years, pictures have been limited to a fairly-pathetic 640 x 640. Now that it's not 2009, and most high-end smartphones have screens that can handle the pixels, Instagram is (finally) upgrading to HD.
In a subtle change that's rolling out across both iOS and Android apps today, photos will now be uploaded, stored, and viewed in a 1080 x 1080 resolution. The web app still seems to be showing pictures at 640 x 640, but fingers crossed there's also an update in the works to fix that. You don't need to do anything to trigger the update -- just sit back, relax, and let the high-definition XProII wash over you.
