Uploading video now goes straight through: your iPhone no longer converts large videos first, so the long wait is gone and the quality stays the way you shot it.
Share a post with a link, videos and your own photos included. Whoever gets the link needs no account.
The camera keeps the viewfinder level when you turn your phone.
360° photos are created entirely on your iPhone: you see a sphere around you fill up as you turn, and stitching happens on your device in seconds.
The app has its own camera with an editor: crop, straighten, filters and sliders for exposure and color.
Digitize old prints in scan mode: edges are detected and straightened, and the camera stays open so you can work through a whole stack.
The posting screen has been reorganized: you see which folder your post lands in before you start, and whether the place your photos were taken goes along.
Security, performance and stability improvements under the hood.
