Move Over ActionScript, Here Comes the New Version...
The most notable difference a programmer will now experience is that ActionScript is now a real object-oriented programming language. This is essential to building scalable solutions for companies that have web applications being used by millions of people each and every day.
Other changes you will notice include a richer print class with methods and properties. The print class supercedes the print functions available with Flash 5.
There are so many new changes with ActionScript 2.0 and I have an article on the new version of ActionScript being prepared for the Guide. I am also working on extending the Guide to include more comprehensive articles on ActionScript.
