If they go to multiple versions I hope they warn us. That was my surprising discovery in the previous post: In MSIE 6 and up there are no version numbers. It's all point zero. At least in the UA string, which may be entirely different from what you see in your "About MSIE" box.
Happily we're now in 10 so it's an easy toggle: either [7-9]\.0; or 10\.whatever-it-turns-out-to-be. I doubt you'll ever get those strings of multiple decimal-delimited sets from browsers that think their UA string is a CIDR ;)
I grabbed the oldest and newest available raw log files. So Chrome has not only jumped forward some 10-to-15 versions, they've added a digit in the UA. Safari itself appears to use 3 sets of numbers when it appears in its own right, 2 when it's part of the Chrome UA string.
