It looks like the new version of CS SDK is still based on the obsolete Flex SDK 3.4.
Is it the case? If yes, are there any plans to release CS SDK based on a more modern version of Flex SDK supporting Spark components?
Harbs is correct. It is based on 3.4
Unfortunatly we are currently constrained by the version used in the Creative Suite. We acknowledge that you like developing for the latest version of Flex and we are working to support it in our next release.
