New Roku HD, 2 and LT updated to version 4.7, slew of 'under the hood' improvements in tow

It's been nearly a month since we saw the Roku 2 and LT get hit with some performance-boosting updates, and now the pair's about to be on the receiving end of some additional enhancements. Version 4.7 -- which is also coming to that new Roku HD -- brings with it a slew of improvements, including refined stability for the aforementioned player and a sharpened device discovery method on the company's Android / iOS applications. Inside v4.7, Roku's also added support for channels using Microsoft Smooth Streaming as well as other improvements to help with launch of "several new partner channels" later this year. The refresh is set to arrive automatically over the next 48 hours, though you could always grab it manually by hitting the Software Update menu on your tiny box.
