Interesting.
5430 Satoshis does seem like a magic number. Any insight as to how it was derived? The release notes just says that's the amount, without explaining why, as if the number just came down on a stone tablet from the sky.
I'm glad to see the lower minimum TX fee. I think it should be even lower. The blocks aren't maxing out yet, at 1MB/block. There's still plenty of headroom to accept more transactions.
5430 must be a clue! To what? I do not know, but a clue nonetheless.
