You have asked 2 questions. First question: Does Cabernet appliance for tvheadend still work? If you go to the github site, the last update was 2 weeks ago, so that does mean it is still being maintained. Second question: Why is the thread so old? The old forum site allowed the top page to be edited and maintained. When they moved to this forum, they locked down the ability to maintain the top of the forum page, so it is static. We still respond to people posting to it, but if no one post for a while, it may look like it is old.
