Boxing Boom,

Flash CS4 supports ActionScript 3.0, 2.0, 1.0, and a few other flavors,
like Flash Lite. In regard to supported languages, CS4 doesn't differ from
CS3. I'm wondering, actually, if you're confusing the name of the product
with the name of one of the languages it supports? When Flash CS3 first hit
the streets, for example, I noticed that a number of people seemed to equate
CS3 with AS3 (which is understandable).

>> Can anyone shine a light, as to how different AS4 is from AS3?

If you're interested in the language itself, keep in mind that Adobe
offers the Flex command line compiler free of charge. That allows you to
build AS3 SWFs without spending a dime on Adobe.

(Look for Flex 3 SDK)

Flex doesn't have drawing tools or a Timeline panel, but again, if your
interest lies in the programming aspect only, working AS3 is free. I can't
predict the future, but I'm comfortable assuming AS4 will also be free ...
whenever AS4 is ready. (Probably a few years yet, but that's just my
guess.)

>> Goddam all those books and CD-ROMS I purchased, already
>> outdated? WTF?

Easy, Killer! They're still useful. :) If if Flash CS4 did support
AS4 -- which it doesn't! -- you can still use Flash CS4 to publish content
for AS3 and any other version of the language.

fairly certain that cs4 does not include a new version of AS. Far as I know it is still AS3 so you should have no worries
