Answer 1

I highly suggest you to not use old versions of JavaScript libraries. They usually have bugs that have been fixed in newer versions.

Chances are good that a very new browser version (especially of IE) results in some issues that are usually quickly fixed in a new version of the library, but if you stay with an ancient version.. well, your scripts might break!
