The document is meant to enumerate various enhancements that will be available in Eclipse Platform release 3.3 from milestone 5. The readers are assumed to be familiar with Forms in general and have some working experience with them. If that is not the case, a good place to start would be Eclipse article: Eclipse Forms: Rich UI for Rich Client Applications as well as online documentation.
Most of the features listed in this document will be available in the integration builds leading to M5 and can be used with the caveat that there is a small change that APIs can change before they are frozen in the M5 stable build. We make these changes only if absolutely necessary and not without the prior warning on the mailing list.
