It possible to compile the Flex 4.6 SDK for any version of the the flash player 10.3 and up.
I've done some very basic testing with versions 10.3, 11.0, 11.1, 11.2 and 11.3. I was waiting
for the full mustella tests to be donated before reapply the patches I made in the patches
branch of the SDK to the new build files.

Yep you could target 10.2 as well. From memory there an issue in SystemManager that stops
you from compiling with 10.2.

The parity release yes but very shortly after that it would be anything form 10.3 and up.

It best to match to the player global version you are using.

All of them (well very soon) see above.

Latest "official" stats from Adobe were June 2011 (which is obviously out of date):

Anyone know of anything more recent?
