2.2.2

* No change

2.2.1

* YAHOO.lang.isObject returns false for null

* YAHOO.lang.isArray no longer generates an error when the argument is null/undefined

* Better error messages for YAHOO.lang.augment/extend failures that are usually due

to missing dependencies.

2.2.0a

* Fixed a typo that prevented the proper detection of multiple YAHOO_config listeners

2.2.0

* Added configuration of the library via a YAHOO_config object defined

prior to the reference to the library. Currently it supports a listener

parameter that will execute every time a new module YUI module is loaded.

* Added YAHOO.register & YAHOO.getVersion for version stamping modules.

* Added YAHOO.env which is the home for the information about the loaded

YUI modules, and will host more info later.

* YAHOO.util.Lang was relocated to this package and is now YAHOO.lang.

YAHOO.extend and YAHOO.augment have moved to env (the original

functions still work).

0.12.2

* No change

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.
