Hundreds of bugfixes, enhancements and performance improvements with many components completely rewritten

New unit tests using a UI event-testing plugin called simulate
Exposed defaults for every plugin
Retrieve and change individual options during plugin runtime
Intelligent plugin cleanup on remove() calls
Easier file structure, fewer dependencies
jquery.dimensions.js now part of jQuery itself
removed the need for *.ext.js files and ui.mouse.js, added a global ui.core.js

Added stack option (bring dialog to front of other dialogs when given focus)
Extended resizable option to accept a list of handles
Added modal dialogs (modal/overlay options)
Added closeOnEscape option (pressing escape while the dialog has focus will close the dialog)
Added bgiframe option (applies bgiframe to dialog; requires bgiframe plugin)
Better position support
Added autoOpen option

non-destrutive drag & drop: can handle fixed, absolute and relative positioned elements, and keeps the setting
better option naming: preventionTimeout becomes delay, preventionDistance becomes distance
new feature: snapping (snap to other elements, like the Winamp windows)
new feature: stack control - let the plugin automatically handle z-indexes
new feature: connectToSortable: allows dragging the draggable into a sortable list

Renamed option autoheight to autoHeight and changed the default to true
Autocreate additional elements required for theme when ui-accordion class isn't present on container element
Enhanced navigation-option by adding navigationFilter-option, accepting a custom filter to find the active panel
Reduced flexibility in terms of markup, in favor of much smoother animations: There must be exactly one content panel for each header

new feature: ranges and multiple handles
huge accessibility improvements: keyboard control, focussing individual handles
new logic: clicking or dragging somewhere other than a handle starts dragging the focussed handle
can generate handles now, with every handle having it's individual max/min option
new-feature: dual-axis slider, allowing do create widgets like colorpickers

Rich interconnectivity
- Connect multiple sortables and allow sorting two-way or one-way
- Serialize sorting results to a url string or to arrays
Drag draggables into sortable lists, drop sortable items on droppables
Improved tolerance
- Three tolerance modes: "intersect", "pointer" and "guess", defaults to "guess"
- Now works for all kinds of different sized elements
Adds much of the draggable functionality: cursor, zIndex, revert, opacity, axis, handles, containment and scrolling
Introduces more callbacks: over/out, activate/deactivate and remove/receive
Better control the placeholder: insert object with element and update callbacks to do what you want

all things zero-based for consistency
show callback is now called on initialization
set selected tab via selected option
set all tabs unselected via selected: null instead of another redundant option
simplified effects options - one fx option (which mirrors jQuery’s default animate options) instead of a bunch of others to remember.
