but in a simple way to tell you waht can you do with the new API and actionscript changes include thghe followinfg things:
classes were reordered yep, the classes were regrouped into four or five groups, and this was possible cos macromedia was bought by adobe so maybe these guys decided to take advantage and change the whole thing inseide....
well as the classses were changed you can now find everything in a more intuitive way, so now classes as colors and dislpay and camera are in different levels of classes or froups. For those wondering what is new inside flash9 the most interesting things i personnally found really interrestinfg are, byteArray, yep now you can save a whole image into a variable and then save it or dend it to php or something, make your own video conferencing site!.....
another interesting thing is key classes were updated, now you can take a more advance control over your keys or keyboard, and last and maybe the most excited, now you can modify sound files or pieces of sound thans to the byteArray, also you can record sound within the flash player to modify it sucjh as you did with the flash 8 filters and matrix classes
