Microsoft has been taken good care of some of its Android apps by constantly updating them. OneDrive and Bing apps have recently received updates.
The major feature OneDrive got was Chromecast support. It works in the usual way – just open up a photo or a video from your OneDrive and a Chromecast icon should appear on to titlebar if there are any Chromecast receivers in your vicinity. There are some other smaller tweaks in OneDrive here and there too. The Home tab, for instance, now prominently features the Recent view with the last files you interacted with, so you can quickly pick up where you left off.

The Bing Android app has basically received a visual overhaul. You can check it out in the screenshots. Many of the features are now easier to access from the Home page and there are also some new additions to the list.
