Actionscript 2.0 Actionscript 3.0 comparison chart
I found this awhile ago and find myself constantly referencing it. Thought I would share the wealth in case you haven’t found this handy AS 2.0 comparison with AS 3.0. It shows you what method, properties, events have been removed from AS 3.0 or what the new syntax or class is in AS 3.0. http://livedocs.macromedia.com/flex/2/langref/migration.html
