Thanks for your question.
Actually, we suspended the development of Silverlight 1.0 controls ever since Microsoft relocated all their efforts in evolving and advancing the new Silverlight 2.0 platform. Strictly following the MS release schedule, we started preparing a brand new controls for Silverlight 2. To cut the long story short, the Silverlight 2 platform allowed us to prepare real "Line Of Business" controls that can help customers achieve rich UI and fast performance with their applications. Such controls were impossible to be developed using the old Silverlight 1.0 edition.
What will happen happen with our controls for Silverlight 1.0?
We will update the suite every time there are some breaking changes in the official Silverlight Plug-in so that the controls can work with the latest plug-in. However, we will not include any new features in the controls for Silverlight 1.0.
