Nvidia has started pushing out a OTA update for the original Shield portable today that carries a pretty hefty amount of changes and file size. The update is simply called OTA 5 Release 82 and weighs in at 158.6MBs in size.
The update adds in quite a few things of importance such as support for the Nvidia Shield wireless controller. That is the new add-on accessory you can get for the Shield tablet. Meaning you can grab the extra controller and connect your current Shield portable to your TV and game that way as well as wireless stream the audio from the Shield Portable to a headset. Nvidia is also replacing the TegraZone app with a new Shield Hub app. You should also see game streaming improvements, Netflix HD support up to 1080p, new onscreen controls and remote GameStream goodies.
If you happen to be the lucky owner of a Shield, be sure to check for the update and get it installed.
