Curious to know why this post has a "unvote" option. I don't recall seeing that before. Is there a link that explains what it does?

Maybe you clicked upvote before coming to the comments?

I see both upvote and down vote on any thread. I used to see only upvotes that flipped to undo. Something changed.

You got more than (I think) 500 karma is what changed. Downvote is disabled for users before that threshold.
