- * Last updated: 18/3/07 to remove iframes on 'out'
+ * YOU MAY DELETE THIS CHANGELOG:
+ * v1.2.1 altered: 2nd July 07. added hide() before animate to make work for jQuery 1.1.3. See comment in 'over' function.
+ * v1.2.2 altered: 2nd August 07. changed over function .find('ul') to .find('>ul') for smoother animations
+ * 				   Also deleted the iframe removal lines - not necessary it turns out
+ * v1.2.3 altered: jquery 1.1.3.1 broke keyboard access - had to change quite a few things and set display:none on the
+ *				   .superfish rule in CSS instead of top:-999em
+ * v1.3	: 		   Pretty much a complete overhaul to make all original features work in 1.1.3.1 and above.
+ *				   .superfish rule reverted back to top:-999em (which is better)
