Instagram received a minor update yesterday, compared at least to the major update of the Video update recently. This update now adds the very much desired landscape mode and video stabilization feature when using the front facing camera.
The landscape support allows for both photos and videos to be shot in landscape mode. The front facing camera stabilization is only available on the IOS version of Instagram at the moment, hopefully this will be coming soon to Android. If you are hankering for front facing video stabilization, Vine have had this feature to their Android app from day 1.
