Question about backwards compatibility of jquery
I know jquery have backwardscompatibility files.

But if you link to this specific version: http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js you don't need backwardscompatibility files. 
I want to know if http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js also is going to work with newer browserversions. Then I don't need to upgrade my jquery to newer versions with the risk that the website doesn't work well anymore.
