The Scaleform 4.6 SDK comes with a variety of add-ons such as Scaleform Video and Scaleform IME that can be downloaded and installed in addition to the base package. These additional products and options are available from here.

Scaleform 4.6 requires Adobe® Flash® Creative Suite® 4 (CS4) or newer. Scaleform 4.6 supports a broad range of Flash Player 10.1 and ActionScript™ (AS) features. While Scaleform 4.6 does not support every Flash or AS feature, the rare occurrence of an unsupported feature has little to no impact on development. Scaleform 4.6 supports both AS 2.0 and AS 3.0. For a complete list of Scaleform 4.6 supported Flash 10.1 and AS 2.0 and 3.0 features, please see Flash Support Overview.

Adobe has done a tremendous amount of work turning the Creative Suite into a unified suite of products which complement one another. This allows the end user to work seamlessly from application to application within the Creative Suite and provides a smoother workflow than was possible before. In some cases however, the newer features and workflow of CS5.5 may not be needed, and, as such, developers may decide to stay with CS4. Obviously, ensuring that each artist and developer are using the same versions of Flash, Photoshop, Illustrator etc will help alleviate workflow strain caused by file version issues.
