Why so many down-votes? The main changes can't be really backported to LuaJIT as far as I know. Otherwise I'd write "great news", then your down-vote warriors would be happy.
The HN community takes a rather strict approach when moderating comments that contribute noise to the conversation. "Nice article!" comments are routinely downvoted. As is sarcasm, witticisms, memes, references and other styles of comments that occur frequently but do not contribute to the discussion. It's a knowingly doomed attempt to hold back the flood of noise that covers Reddit.
