Dear sir or madam,
My team is programming a system which is based on jquery1.5.2, but now we got a very serious problem which is bug #10137(http://bugs.jquery.com/ticket/10137) on IE9 (we used dtd of xhtml1.0, but we think it's not much bearing on this problem).
This problem is so serious that will impact the performance of our system on IE9. Because of the day of product release is very close, we don't want to solve the problem by updating to 1.7.2. Could you tell us which parts were modified? Cause we want to solve this problem on jquery1.5.2 if we can. However, if the parts have to be modified are too much that we have to update to 1.7.2, could you tell us if there are any other changes or parts that might cause some bugs, which are not listed on the Relese Notes?
