yes this would be a very useful feature although it's currently not possible
All you can do is use the information they provide for every class which tells you what version of Flash Player, AIR, etc is required to use it. Very few things get added cycle to cycle, it shouldn't be a hard task to figure out if what you want to do is possible at a particular version.
isn`t there a possiblity that adobe Employee has the list??
We are starting to do this. To see what I mean, go to the Beta Platform ActionScript Reference (http://help.adobe.com/en_US/FlashPlatform/beta/reference/actionscript/3/) and click What's New. It shows you all new APIs in Flash Player 11.3/AIR 3.3. I will keep asking around, but am not sure we have this information readily available for previous releases.

I said that I want AIR 3.1, AIR3.2 , FP11.1 and FP11.2...
I don't understand...
If Adobe can't make the list, who can do that??
well by the looks of things you can't have it (yet)
Adobe can make the list (probably) but they haven't and by the looks of things don't have plans too just yet, although it's something they might back date in the future
