After more than six months in beta, the Adobe Flex developer team has posted on their official blog the final version of the Flex 4 SDK and Flash Builder 4 (formerly Flex Builder). While the Flex SDK is available for all platforms, Flash Builder 4 is currently only supported on Windows and Mac OS X - Linux developers will need to continue running the alpha version of Flex Builder 3 available at Adobe Labs. The Flex SDK is free to download and use without cost, while Flash Builder is available as a trial download and requires purchase.

Among the Flex 4 SDK's main changes are the new components architecture, changes on skins creation and improvements on states. Amidst Flash Builder 4 changes, besides the name, the support for automated tests using FlexUnit stands out. Its new development workflow and improvements on productivity tools like refactoring, debugging and code generation are also highlights.
