JQuery 1.6 released
I wasn't entirely sold on the splitting up of attributes and properties at first.  After all, a big part of jQuery is adding convenience, and this does remove a certain amount of convenience at the end of the day, even if only a little.  Then I got to the performance graphs at the end.  Those are some impressive speed ups for almost all the browsers (1). The speed + more logical separation seems totally worth it.(1) Except, you know, ie 7 and ie 8.  So... half the internet.
