A.3. Summary

This was a terse and introductory write-up on Flex 4, the new Flex framework. Being a brief write-up, it concentrated on getting you started, setting the context for the discussions and exposing you to the first bits of the new framework.

The write-up has two parts. The first of these two parts described the new features and the backward-compatibility capabilities of Flex 4. The second one illustrated a typical development workflow and walked through an elementary application.
