Now that the Flex SDK has migrated to Apache, I can't seem to find old versions of the Adobe Flex SDK. I'm maintaining a legacy project that will not compile with the latest Apache Flex SDK, and I cannot afford to spend time overhauling the whole project for some minor bug fixes. I'd prefer to continue using the same Adobe Flex SDK that the app was originally developed with. Where can I find old builds of the Adobe Flex SDK?
