Google released the RC1 of GWT 2.1. "While we're still focused on overall theme of making it easier to build cloud portable business apps via some help from VMware and Spring, there're more than a few aspects that make this milestone a RC. First rounded out the list of components and features shipping with GWT 2.1. One of these components is a Editor framework that allows to bind your DTOs to a customizable UI which handles all necessary grunt work of validating and syncing change sets. Another is the SafeHTML component and its integration within the cell-based widgets.
As with previous milestones, there'll be an associated Spring Roo RC1 and SpringSource Tool Suite RC1, that'll be available in the next few days.
