Microsoft is pushing an update to Mail and Calendar for Windows 10, bringing it up to version number 17.6118.420001. While updates are always a good thing, this one unfortunately doesn't come with a changelog. But, hey, at least they're consistent.
We haven't been able to spot anything notable in this update, but there's a chance something slipped by. If you happen to notice anything, be sure to shout out in the comments below. And do note that, so far at least, this update appears to be only pushing out to Windows 10 desktop, but we'd expect a push to Windows 10 Mobile won't be too far behind.
