There's no changelog, but there is one change of note. Although it's not the most exciting thing in the world, the Settings menu has seen some tweaks that simplify things a bit. As seen below, there is a new "Manage Subscription" option on the left side of the screen, while the options under the "More" heading have been trimmed down a bit.
Aside from the settings tweaks, this update probably includes some performance improvements as well. Keep in mind that this update appears to be only hitting Windows 10 desktops right now, though we wouldn't expect a mobile update to be too far off.
