Release levels of jQuery?
I have some jQuery code that I wrote 4 or 5 years back. They files include these lines, which I think were the current release levels at the time I wrote the code:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script src="
http://ajax.aspnetcdn.com/ajax/jquery.validate/1.10.0/jquery.validate.js"></script>
I'm back updating the code now. Should I be updating the versions of the code to the now-current version or is it fine to leave the levels are they are? Is there any danger in changing the levels? Would I need to retest my code "just to be safe" if I did that? What *are* the current levels and how do I find out for myself when I'm in doubt?
