What's the latest software version?

what's the newest software version available to Bolts? Mine has this really annoying problem where it seems to have some sort of HDMI handshake issue between the Bolt, my receiver and my TV. I thought I had read this was fixed in the latets release, but I'm not sure what the latets release is so I'm not sure if my Bolt has it or not.
