Tell HN: iPhone app update approved in less than 6 hrs on a Sunday

I submitted an update for one of my iPhone apps this afternoon, probably after 1:00pm. I just noticed it has been approved and is now available for sale, less than 6 hrs later. It was a pretty big update that I did not think would be available until after the holidays so I'm a little shocked. Has this happened to anyone else? Does it maybe have something to do with the holiday break that's coming up?
