Is there a compatibility plugin for using jQuery UI 1.7.2 with jQuery 1.4?

Is there a compatibility plugin for using jQuery UI 1.7.2 with jQuery 1.4?

Hi all, 

I understand that we need to wait for version 1.8 in order to use it jQuery UI with jQuery 1.4, but when watching the jQuery 1.4 Q&A I thought I heard John Resig say something about a compatibility plugin that could be used until the 1.8 release was available. 


Is this right? Does such a plugin exist? 

TIA
