YAHOO Global Namespace - Release Notes
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.
