YAHOO Global Namespace - Release Notes



0.12.1

  * No change



0.12.0



   * Added YAHOO.augment, which copies all or part of the prototype of one

     object to another.  



   * YAHOO.namespace now can create multiple namespaces.



   * Added an optional third parameter to YAHOO.extend: overrides.  It takes

     an object literal of properties/methods to apply to the subclass

     prototype, overriding the superclass if present.



0.11.4



   * Changed window.YAHOO = window.YAHOO || {} to 

     if (typeof YAHOO == "undefined") YAHOO = {} because the previous statement

     contributed to a memory leak in IE6 when the library was hosted in an 

     iframe.



0.11.3



   * Changed var YAHOO = window.YAHOO || {} to window.YAHOO = window.YAHOO || {}.

     This fixes an issue in IE where YAHOO would get overwritten if previously

     defined via array notation (window["YAHOO"]).



0.11.0



   * Added YAHOO.extend, which provides an easy way to assign the prototype,

     constructor, and superclass properties inheritance properties.  It also

     prevents the constructor of the superclass from being exectuted twice.



0.10.0



   * Added YAHOO.log that provides a safe way to plumb logging statements in

     code that will work if the logging component isn't available.
