 Slider - Release Notes
 
+0.12.0
+
+   * Added "slideStart", "slideEnd", and "change" custom events.  The abstract
+     methods these will eventually replace still work.
+
+   * The default animation duration is 0.2 seconds (reduced from 0.4 seconds),
+     and is configurable via the animationDuration property.
+
+   * Keyboard navigation is now built in.  The background needs a tabindex for
+     keyboard nav to work.  Keyboard nav can be disabled by setting enableKeys
+     to false.  The number of pixels the slider moves when the arrow keys
+     are pressed is controlled by keyIncrement, and defaults to 20.  Note, 
+     Safari support limited to background element types that support focus
+     in that browser. http://bugs.webkit.org/show_bug.cgi?id=7138

+   * Fixed broken doctype in examples/index.html
+

+     autocomplete="false" has focus
