Title says it all. We've just released:
 
  • ColdFusion Builder – This new Eclipse-based IDE for ColdFusion development is deeply integrated with ColdFusion 9 in addition to making it fast and easy for CF developers to create Flex applications with integration between ColdFusion Builder and Flash Builder.
  • Flex 4 – Including the new Spark skinning and component architecture enabling a new level of expressiveness in RIAs in addition to supporting the new Flash Catalyst to Flash Builder workflow.
  • Flash Builder 4 - There are over 90 new features in this release, and you can use them with both Flex 3 and Flex 4 to gain big improvements in development time, integration and building more expressive apps.

ColdFusion Builder is priced at $299 and comes with a copy of Flash Builder 4 Standard. Or, for $699 you can buy Flash Builder 4 Premium which also includes a copy of ColdFusion Builder. Worth noting: like ColdFusion itself, ColdFusion Builder is free for educational purposes.
