Flash versions: features and usage?

[Henri Karapuu]

I'm trying to find detailed information of what features are supported
in different flash versions. Also percentage of people using each
version would be very helpfull.

If i'm not badly mistaken Flash 1 and 2 don't support alpha, and only
4 supports properties, but i would need much, much more detail on
these. Pointers to web-sites will do fine. I found also that roughly
80 percent of web-users have flash support, but the article didn't
have any detail how this 80% is divided between different versions.

Thanks in advance,
