Not only Mail & Calendar but Xbox, Camera & Calculator apps on Windows 10 have also snagged updates.
Real-time Friends list presence. Your Friends list will automatically refresh with your friends’ on/offline status and the apps and games in which they’re currently engaged – including whether the game they’re playing can be joined via multiplayer or party.
Real-time Activity Feed updates. No need to hit refresh to see new Activity Feed items; keep the Xbox app open and your Activity Feed will let you know when there are new items to view, comment on, like, or re-share.
Game progress comparison. Feeling competitive? Discover how you stack up against your friends on specific game progress by visiting the Achievements section of your profile and selecting ‘Compare.’ You’ll enjoy a side-by-side comparison of your selected friends’ progress on games you’ve recently played, including game completion percentage, Gamerscore and Achievements earned.
Console text entry. We’re also bringing one of the most requested features from Xbox Feedback to the Xbox app on Windows 10 – the ability to use the Xbox app for text input on Xbox One. You will now be able to use the Xbox app and other inputs compatible with Windows devices – keyboards, touch keypads, and the like – to enter text in search boxes and more on Xbox One.
– Try the new programmer mode, with added logical operations.
– Scientific mode also includes new functions.
– You can now switch between dark and light themes.
– It’s easier to use and faster than before.
Though these changes don’t reflect on Mobile devices on checking.
There is not much to report for Camera and there is no official changelog either. So we can assume bug fixes and improvements.
