It appears that Adobe has released the final versions of Flash Builder 4, ColdFusion Builder, and the free Flex 4 SDK. Use the links below to navigate to the respective product pages. A great learning resource to use if you’re new to Flex is the Adobe Flex DevNet. I wonder if this is a sign of an imminent release of Adobe Flash 10.1?
