Note: Flex SDK 4.1 has been released which provides support for the Flash Player 10.1 and Adobe AIR 2 runtimes, critical bugfixes as well as the new Layout Mirroring feature.
As a product manager for Flex I've talked with many people about the upcoming release of Flex 4, including customers and our own development team, and the level of excitement around this version is higher than any I've seen in the past. We are providing releases of the two tools geared towards Flex: Adobe Flash Catalyst (currently in beta) and Adobe Flash Builder 4; but the foundation for it all is the Flex 4 SDK. This article provides an overview of what you'll encounter as you play with the new SDK and framework.
