Just as promised, Silverlight 3 has been released, actually 1 day earlier than the expected July 10th date. You can get the latest tools here.

For those of us who have been already playing with Silverlight 3 beta, there are some breaking changes. The most obvious one is that the System.Web.Silverlight assembly has been removed, meaning that the ASP.NET Silverlight control that we were using won't work anymore. Alternately, you need to set up your Silverlight app using an object and an iframe tag. The object tag shouldn't be new to anyone and was always an alternative to using the Silverlight control. The iframe will be used to handle browser history, which comes along with the new SL3 Navigation features.
