Yup, I noticed right away yesterday and wondered the same, but decided to hold off on commenting until the next report(s) come(s). :-) I figured it might have happened "between some changes that weren't optimal," but after the commits were finalized, etc. it would be sorted out again. But this does seem pretty extreme, and I don't recall seeing radical changes since the last one... *shrug* - Matt
