I don't have any involvement with Metallifillifillifillifillizzefiillizer, so I can't say anything definite about it 'cause I don't know anything.
But if I'm not mistaken, it's one of those "freebie, not supported" thangs. Which would usually mean that it would only get updated when there's absolutely nothing better to do.
But again, I'm just speculating - I don't actually know anything about it.
