Native Calendar and Bing suite of apps for Windows Phone have received updates. Though Calendar app has run into issues of crashing while trying to create an event post update. Also, there is no changelog provided for what has changed in Calendar, so seems Microsoft will need to update it again.
Bing suite of apps have also been updated and as you can in above screenshot my Lumia received updates for Weather, News and Sports. These again come without a changelog, so time to let us know if you find anything yourself.
