Make sure that the right event type is always triggered (was causing problems with UI's event triggering).

Made the expando code attach properties to an anonymous object, as opposed to the global window object, and fixed a bug where .removeAttribute() tried to fire even if it didn't exist.

Added an extra check for removing a named cache property - calling it when it didn't exist caused an exception.

Landing a version of $(document)/$(window) .width()/.height(). It won't win any awards, but it'll hold us over for this release.

So, apparently, I never committed the second half of the new field value code. This allows you to set values on groups of checkboxes, radio buttons, and selects.

Plugins will be most interested in:
- jQuery.data(elem) -> Unique ID for the element
- jQuery.data(elem, name) -> Named data store for the element
- jQuery.data(elem, name, value) -> Saves a value to the named data store
- jQuery.removeData(elem) -> Remove the expando and the complete data store
- jQuery.removeData(elem, name) -> Removes just this one named data store

jQuery's .remove() and .empty() automatically clean up after themselves. Once an element leaves a DOM document their events are no longer intact. Thus, statements like so:
{{{
  $("#foo").remove().appendTo("#bar");
}}}
should be written like so:
{{{
  $("#foo").appendTo("#bar");
}}}
in order to avoid losing the bound events.

Landing the .clone() rewrite by Brandon (also includes the new event cloning functionality .clone(true)).

Added the new .offset() method, directly imported from Dimensions (heavily worked over by both Brandon and John).

- You can now animate non-px values (em and %, for example)
- You can animate things things that previously broke (like font-size)
- You can now write fx plugins (to add in the ability to animate colors, for example)
- Advanced queueing controls were added (.queue(), .dequeue(), and {queue:false})
- Step was re-tooled to work with the new fx plugin scheme
- Added the ability to do relative animations
- Made it so that you can do simultaneous animations on a single element
- A complete refactoring of jQuery.fx, improving naming, and usability

Fix for bug #760 (fontSize returns different values in IE). This was part of a larger issue where IE returned non-pixel values from it's computed style - this normalizes it (thanks to a fix by Dean Edwards).

- New method: .serializeArray()
This returns an array of name/value pairs representing the contents of a form, or individual input elements.
- Enhancement: .serialize()
The results are correct now (as opposed to the mess from before), and allows you to serializes forms directly (rather than just the input elements).
- Enhancement: .val()
This now returns the correct value when dealing wih selects. Additionally, when dealing with multiple selects, it returns an array of values.

Based upon Mike's code:

and test suite:

Added support for the new .andSelf() method. This method combines the previous two matched sets on the stack into a single stack.

For example:
  $("#foo").parent();
  // => [ #bar ]

  $("#foo").parent().andSelf();
  // => [ #bar, #foo ]
