Porting in jquery 1.4

I would like to upgrade the site from 1.3.2 to 1.4, as I see that there are some good performance improvements.

  • Can I just give it up? Am I worried about my plugins at work?

  • Is it backward compatible?

  • What should I worry about?

Best to try and see. jQuery14.com has a backward compatibility list , as well as a 1.3-compat plugin that you can use to mitigate the shock.
