Compare Flex 3 and 4

Question

Where can I find a chart or some article to compare Flex 3 and new 4.

Answer 1

The official Adobe Flex 4 Open Source site is currently the best place to find information about this upcoming version of the framework. It's worth noting, however, that Flex 4 is still in development, and they don't even consider it beta yet. This could change significantly between now and the final release.

UPDATE:

Beta 1 released 1 June 2009.
