 You can replace the file with the uncompressed version for development if
 you wish.

 Since WP uses Prototype in places(Or at least still includes it) Prototype
 gets the $ variable. (As it was included first, its backwards
 compatibility)

 To work around that, jQuery has allowed for a $.noConflict() mode which
 jquery operates in with WP, when noConflict mode is enabled, jQuery no
 longer uses the $ value, only the jQuery value. (ie. $.function() =
 jQuery.function() )

 Previously, when noConflict was enabled, $ would still stay assigned to
 jQuery if nothing else was using it, in the latest however, when no
 conflict is enabled, it seems that $ is no longer assigned. (It seems this
 is to do with the "Any Name jQuery" function:
 http://jquery.com/blog/2007/08/24/jquery-114-faster-more-tests-ready-
 for-12/ )

 Theres a work around for this too, allthough, i'm not sure of it, someone
 else will hopefully be able to give the correct syntax, but from pure
 memory its something like this:

 {{{
 jQuery( function($){
 //Use $ here
 });
 }}}

 Personally i've added this to the top of a few options pages for my
 plugins:
 {{{
 $ = jQuery;
 }}}

 So, What i've been trying to say, is that its the noConflict() mode which
 will be breaking your script.

 Also, as a side note, The reason 1.2 isnt included in 2.3 is to keep the
 same stable line, See #4952
 and see #4977 for interface related issues with jQuery
