Here's what's improved in today's Surface 3 firmware update

Earlier today, Microsoft released new firmware for the Surface 3. At the time, there was no changelog available, but now - over ten hours later - we finally know what's included in the update.

The new firmware is different depending on whether you're running Windows 8.1 or 10. Here's what got improved if you're on Windows 8.1:

This raised speculation as to whether or not a Surface 4 is in the works, but there have been no credible rumors.
