Introduction to Flex 4

Adobe® Flex® 4 introduces many features including a new skinning and component architecture, a new animations engine, an extended layout mechanism, a new text engine, and a new graphics library.

If you are already a Flex developer, you should become familiar with these new features before starting development with Flex 4. For additional information on migrating applications from a previous version of Flex, see the Adobe Flex 4 Features and Migration Guide at http://www.adobe.com/go/learn_flex4_featuremigrate_en.

If you are a new Flex developer, and have not previously developed applications in Flex, you can use the many available resources to learn more about Flex. For more information on the resources available for new Flex developers, see Getting started with Flex 4.
