The Windows Camera and Calculator apps have been updated across both Windows 10 and Windows 10 Mobile today. Unfortunately, there's not much to look forward to. As is par for the course now, there aren't any new changelogs included with either update. However, Windows Camera is looking at a version bump from 5.54.2001 to a whopping 5.54.2002, while Calculator moves from 10.1508.14020 to 10.1509.14010.
It's likely these updates are just performance improvements and bug fixes, which, while not captivating by any stretch of the imagination, are never a bad thing. You can go ahead and update from the links below, and be sure to shout out in the comments if you happen to notice anything new.
