A new update was picked up by Instagram for Windows 10 on Sunday in the Windows store, bumping it up to version 188.8.131.52 and bringing it in line with other platforms.
The new update does not bring anything significant except from a new look and a new logo.
Here's the changelog:
We have a new look! Our updated icon stays true to the camera and rainbow. The simpler design puts more focus on your photos and videos without changing how you navigate the app.
