Good news for you Xbox 360 users out there (we hope that's most of you), the Companion app has received a nice little update to v1.1 this morning in the Marketplace.
Unfortunately, no word on what the changes are as there seems to be no obvious new features on board. But perhaps coincidentally, our Xbox 360 just received a system update to its OS and maybe the two are related. Or not.
(Edit: Today's Xbox 360 update is "... to quickly fix some voice recognition issues affecting our non-English speaking members" according to Microsoft's Major Nelson.)
Go download the app in the Marketplace here and in the meantime, we'll work on nailing down a changelog for ya. Thanks, Kyle S., for the heads up
