Microsoft has pushed out updates to a number of built-in apps in Windows 10 Mobile.
Unfortunately as is usual with Microsoft the updates come without changelogs (would that be so hard Microsoft?) and we have to assume the usual bug fixes and performance improvements.
Updated apps include Mail and Calendar, Camera, Calculator, Block and Filter and OneDrive.
From the list the only one with a visible change is OneDrive, which has seen the Sort icon moving from the ellipses menu to the navigation bar.
The apps can be found at the links below:
