Microsoft has made available "Internet Explorer 9 Compatibility Cookbook," which is designed to help you understand changes in Windows Internet Explorer 9 that might impact applications that you developed for earlier versions of Windows Internet Explorer. Many changes help Internet Explorer comply with broader industry standards, and other changes improve performance and reliability.
The Internet Explorer 9 Compatibility Cookbook includes information about changes to features, identifies features that are deprecated or removed, and describes general tools and guidance.
New topics will be added to this section as features are modified and as you identify areas where you need more information.
