Both have been promised as coming soon in recent weeks, and now Boxee has confirmed that two fairly big new rollouts are underway. The first is the Boxee Box Live TV dongle, which is now shipping and will let you augment your Boxee Box with some OTA TV channels for $50. You can get a closer look at it in our hands-on from CES earlier this month. Alongside it, Boxee is also rolling out its Boxee 1.5 software update, which boasts a new UI and a number of other refinements including better search, new library screens and filtering options, browser pop-up management, and the addition of Rotten Tomatoes listings. Boxee says it’s staggering the release over the next 72 hours, but those eager to check it out can find instructions for a manual update at the support link below.
