Connection Manager Release Notes
*** version 0.12.0 ***
* When uploading files via setForm() and asyncRequest includes a POST data
argument, appendPostData() will create hidden input fields for each postData
label/value and append each field to the form object.
* setForm() returns the assembled label/value string of the parsed HTML form
fields.
* NOTE: Opera 9.02 does not allow for more than 12 concurrent Connection Manager
objects.
The following example creates 12 requests in a loop:
for(var n=0; n<=12; i++){
conn[n] = YAHOO.util.Connect.asyncRequest('GET', sUrl, callback);
}
If n > 13, Opera 9.02 will crash. Connection manager objects count n must be <=
12 at all times. This condition was not present in Opera version 9.01.
This condition does not apply to other A-Grade browsers (
http://developer.yahoo.com/yui/articles/gbs/gbs_browser-chart.html)
*** version 0.11.3 ***
* YUI Event dependency for file uploading is now optional.
* uploadFile() now sets unique IDs for each file upload transaction to prevent
iframe collisions with parallel uploads.
* The callback object now has property responseXML to provide support for file
upload transactions that return an XML document.
* setForm() will verify if a select option value attribute is present and use
its value, including empty string, before using the text node value.
* Modified polling mechanism in handleReadyState() and
handleTransactionResponse() to prevent infinite polling if JavaScript errors
occur in the user-defined callback.
* createFrame() will now accept a boolean argument of true to set the frame
source to "javascript:false" to prevent IE from throwing security warnings in an
HTTPS environment.
* setHeader() now enumerates through the _http_header object using
hasOwnProperty() to prevent collisions with members added to Object via
prototype.
* If using setForm() and asyncRequest includes a POST data argument, the data
will be concatenated to the HTML form POST message.
*** version 0.11.2 ***
* No revisions.
*** version 0.11.1 ***
* uploadFile() now verifies the existence of callback.upload before invoking
callback, with or without object scope.
*** version 0.11.0 ***
* Each transaction can be defined with a timeout threshold, in milliseconds,
through the callback object. If the threshold is reached, and the transaction
hasn't yet completed, the transaction will call abort().
* abort() will now accept a callback object as the second argument. The
failure callback will receive a response object to indicate the transaction was
aborted.
* setForm() will now support file uploads by setting the second argument to
true (e.g., YAHOO.util.Connect.setForm(formObject, true). File upload does not
use the callback success or failure handler. Instead, it uses a new callback
object handler: upload.
* HTML form submit will no longer submit form fields without a defined name
attribute.
* The default POST header of 'Content-Type','application/x-www-form-urlencoded'
can be overridden by calling setDefaultPostHeader(false). This
will remove the default header from non-HTML form, POST submissions.
* setHeader() now enumerates through the _http_header object with
propertyIsEnumerable to prevent collisions with members added to Object via
prototype.
*** version 0.10.0 ***
* handleTransactionResponse() now treats the full HTTP 2xx range as a success
case, instead of just HTTP 200.
* To accommodate multiple field values in Mozilla/Firefox, multiple initHeader
calls with the same label will now result in the values concatenated to a
comma- delimited string value.
Example:
Setting Content-Type:'application/x-www-form-urlencoded' and Content-
Type:'text/xml' will result in Content-Type:'application/x-www-form-urlencoded,
text/xml'.
* Default polling interval lowered to 50ms.
* YAHOO.util.Connect.setPollingInterval() will allow you to set a polling
interval -- in milliseconds -- to override the default value.
* YAHOO.util.Connect.getResponseHeader[headerLabel] now supported as a response
object property to provide symmetry with the native XHR object's property.
Example:
YAHOO.util.Connect.getResponseHeader['Content-Length'] will return the value
for the Content-Length header, if the header is available.
* YAHOO.util.Connect.allResponseHeaders property renamed to
getAllResponseHeaders to provide symmetry with the native XHR object's
property.
* YAHOO.util.Connect.setForm() now supports HTTP GET as well as HTTP POST.
* YAHOO.util.Connect.setForm() now accepts an HTML form object as well as its
name attribute value.
* YAHOO.util.Connect.setForm() will not submit HTML form fields that are
disabled or do not have a name attribute value.
* [FIXED] Response exceptions result in infinite callback loop in
Mozilla/Firefox.
* [FIXED] YAHOO.util.Connect.abort() now properly clears polling interval.
* [FIXED] isCallInProgress() now verifies whether XHR instance still exists,
and returns false if the connection object is no longer available.
*** version 0.9.0 ***
* Initial release

YUI Library - Event - Release Notes
0.12.0
* If the function argument is not provided to Event.removeListener, all
all listeners for the specified event type on the element will be removed.
* CustomEvent now has an optional parameter that defines the signature of
the listeners for this event. Two signatures are supported:
YAHOO.util.CustomEvent.LIST:
param1: event name
param2: array of arguments provided to fire()
param3: <optional> the custom object supplied to subscribe()
YAHOO.util.CustomEvent.FLAT:
param1: the first argument provided to fire()
param2: <optional> the custom object supplied to subscribe()
The new flat signature makes it possible to provide a better API
when using custom events, and it makes it possible to transparently
wrap DOM events.
* The parameters for overriding scope in both Event.addListener, and
CustomEvent.subscribe have been augmented. In addition to the
previous behavior where a true value would make the previous parameter
the execution scope, an object can be supplied instead. If an object
is provided, that object becomes the scope obj. This makes it possible
to pass a both a custom object and adjust the scope to a different object.
* Added EventProvider, which is a wrapper for CustomEvent that makes it
possible to subscribe to events by name, whether or not the event has
been created. This class was designed to be used with YAHOO.augment.
EventProvider custom events are created with the new FLAT listener
signature.
* CustomEvent subscribers can return false to stop the propagation of
the event.
* CustomEvents now have an onSubscribe custom event that can used to the
case where a subscriber subscribes to an one-time event that has already
happened. Also provides a way for the implementer to defer initialization
logic until after the first subscription.
* Event.getCharCode now always returns keyCode if charCode is not available.
* Added Event.onContentReady, which is similar to onAvailable, but it also
checks simblings to try to determine when the element's children are
available.
0.11.4
* Fixed a memory leak in IE6 that occurred when the utility was hosted in
an iframe.
* Fixed an issue with Safari click listeners when listeners were removed.
0.11.3
* The listener cache is now pruned when events are removed. This fixes
a performance issue when adding many listeners, removing them, and
adding them again repeatedly.
* Safari click listeners will work correctly if a bound element is removed
from the DOM and a new element with the same ID is added.
* Removed the code that automatically unsubscribed custom event listeners.
0.11.0
* Added Event.purgeElement which will remove all listeners added via
addListener from the supplied element. If an optional "type" parameter
is supplied, only events of that type will be removed. Optionally, the
purge can be performed recursively on the element's children as well.
* Added Event.getListeners which will return all listeners attached to
a given element.. either all listeners or listeners of a specific type.
* getTarget now automatically resolves text nodes. The optional parameter
for this feature is now deprecated.
* getRelatedTarget now resolves text nodes for the browsers that return the
text node rather than its host HTML element.
* CustomEvent now logs the custom event activity if the logger widget is available
0.10.0
* Added Safari dblclick to the list of legacy events.
* When multiple identical event handlers are defined, multiple calls
to removeListener can now remove all of them.
* removeListener works properly for unload events
* Legacy event bookkeeping is more efficient, improving the performance for
adding Safari click events.
* _unload() is more efficient, improving the page transition experience in
Safari in particular.
* addListener, removeListener now return false if the function argument is
not valid.
* Fixed an operator precedence issue in getCharCode.
* Added Event.getXY, which returns [Event.getPageX(e), Event.getPageY(e)]
* Added Event.onAvailable, which will execute the callback when the element
with the supplied id is found. Currently searches periodically until the
window load event or for up to 10 seconds after the onAvailable method
was executed.
* The lazy listener attachment process now will poll beyond the window load
event in order to better handle the case when a listener is defined
late in the page but before the element is in the dom.
* Fixed browser detection for Opera installations reporting as IE.
* It is now possible to remove and re-add legacy events (Safari click event).

TreeView - Release Notes
0.12.0
* TreeView now augments EventProvider, and has custom events for expand,
collapse, animStart, animComplete, and labelClick. Existing implementations
using abstract methods for these events (if they exist) will still work.
New events can be plugged into the tree by the Node implementation. For
example, TaskNode adds a checkClick event. EventProvider makes it safe
to do this because implementing code can call subscribe() prior to the
event creation.
* YAHOO.util.Event is now a requirement for the widget
* TreeView::removeChildren no longer expands and collapses the node.
* Documented the moveComplete property
* createElement("DIV") changed to createElement("div")
0.11.4
* Fixed a javascript error on the HTML node example page.
0.11.3
* popNode now clears the tree, previousSibling, nextSibling, and parent
properties of the node that is being removed from the tree.
* Fixed the paths to the images in the tree.css file that is included in
build/assets.
0.11.0
* Added TreeView -> popNode, which differs from removeNode in that the
node's children are preserved so the entire branch can be re-inserted
into another part of the tree, or another tree.
* Added TreeView -> getNodesByProperty, which differs from
getNodeByProperty by returning an array of all nodes that have the
specified property rather than just the first one.
* Added Node -> insertBefore, insertAfter, and appendTo. These method
can be used to reorganize the tree.
* removeChildren properly resets the node icon when executed against a
collpased node.
* Moved depth assignment from the constructor to appendChild so that the
value is set properly if the node is moved within the tree.
* Fixed broken loop in removeChildren.
* RootNode -> loadComplete calls tree.draw for hot-wiring the dynamic load
feature for the top level nodes.
* The treeview constructor will accept an element instead of an id.
0.10.0
* If the child collection changes prior to a refresh(), the icon is now
changed appropriately.
* Added TreeView removeChildren(node). This will recursively purge the node's
children, and reset its dynamic load state.
* previousSibling and nextSibling are now adjusted correctly when a
node is deleted.
* expand()/collapse() now will not expand/collapse the node if false is
returned from the onExpand/onCollapse event handlers.
* The onExpand and onCollapse events now fire before the node is expanded
or collapsed so that the implementer can modify the node's child collection
prior to display.
* The childrenRendered property previous was used to indicate both that
a dynamically loaded node has received its data, and also to indicate
that the children html has been created. This has been split into
two properties. dynamicLoadComplete and childrenRendered.
* Implemented the renderHidden flag. If set to true, the html for the entire
tree will be created when tree.draw() is called, not just the html for the
visible nodes.
* Added an onLabelClick listener to TextNode
* TreeView.removeNode no longer automatically refreshes the tree. It has an
optional parameter to perform the refresh.
* removeNode can now be executed on nodes that have not been rendered.
* You can now delete top-level nodes.
* Added onCheckClick listener to the TaskNode example
* Added Node.iconMode, which is a property that configures the way
dynamically loaded nodes are displayed when they are expanded and contain
no children.
* TreeView/Node.setDynamicLoad now accepts an optional second parameter to
set the iconMode property.
* Fixed an issue in the TaskNode.js example that prevented setting the checked
state of a node through the constructor.
* Fixed an issue in HTMLNode that caused rendering issues when hasIcon was
set to true.
* Added TreeView.removeNode
* Added Node.refresh

utilities.js Release Notes
*** version 0.12.0 ***
The utilities.js file rolls up all of the YUI utility components into a single
file; it includes the following components:
* Yahoo Global Object
* Event
* Dom
* Connection Manager
* Animation
* Drag & Drop
For implementations that use a significant subset of these files, it may prove
more efficient to include utilities.js as opposed to including separate files
for each component.
Note: If you are require only the Yahoo Global Object, Event Utility and Dom
collection, consider using the special yahoo-event-dom.js aggregate instead.

yahoo-event-dom.js Release Notes
*** version 0.12.0 ***
The yahoo-event-dom.js file rolls up the three most commonly-used YUI Utilities
into a single file; it includes the following files:
* Yahoo Global Object
* Event
* Dom
These three files serve as a common foundation for most YUI components and
third-party implementations. On pages where you do not need additional YUI
Utilities (Connection Manager, Animation Utility, Drag & Drop Utility), the
yahoo-event-dom.js aggregate will often be an optimal choice.
Note: If you do require additional utilities, the full utilities.js file is
provided in this distribution; utilities.js includes all YUI Utilities in a
single file.
Please see the blog article on www.yuiblog.com titled "YUI: Weighing in on
Pageweights" at http://yuiblog.com/blog/2006/10/16/pageweight-yui0114/ for more
details.

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.
