jQuery UI 1.7.2 vs jQuery 1.8.5 - do I need to change my 1.7.2 theme created by themeroller?

I am switching to jQuery 1.8.5 and was wondering if there's anything there that might break my jQuery UI 1.7.2 theme created b开发者_如何学运维y themeroller. Do I need to create a new theme (because of new effects, etc) or can I just re-use my old CSS files?

Thanks!

You need new CSS, there are several code changes (and even new widgets) that need updated CSS.

Your current jQuery UI CSS file should have a URL inside a comment, like this:

To view and modify this theme, visit http://jqueryui.com/themeroller/?....

Just go to that URL to get the updated/current version of your theme, so you don't need to reconfigure colors and such.
