The first release candidate of Echo3 is now available. This release is identical to the very well tested SVN 2270 version. An updated release of Echo3 Extras will follow in the near future; in the interim the Echo3 Extras build 1386 should be used.
Beta2 is a complete re-imagining of EchoStudio for Echo3. The Form and StyleSheet editors have been redesigned, and now provide support for undo/redo along with faster and easier property editing. The product has been moved from a downloadable plugin to a proper Eclipse update site, such that users can easily upgrade to later releases.
A new default theme has been added to the application templates, reminiscent of the Echo3 demo application. The public domain Tango icons are additionally included. Together they can be used to create great looking applications with little effort.
All property editors have been overhauled for both efficiency and ease of use. Experienced users can (optionally) enter properties as text strings directly into property tables. For example, one could simply type "2px red" directly into a border field. Most property editing dialogs have been redesigned as well. A new menu editor allows for visually creating Extras
Beta8 adds a much improved TabPane with the capability to render custom graphic borders around tabs. RichTextArea has been overhauled; enhancements include improved aesthetics, cross-browser support, a more standard document format, and new features such as table editing. In server-side Java applications, text components can now progressively notify the server as a user types, making it possible to create "auto complete"-type components with only Java code. Architectural improvements have been made to the framework itself, including new APIs for component developers to receive keyboard events without worrying about browser peculiarities, and an easy and fast API for rendering image-based borders.
A new Echo3 File Transfer Library has been under development during the past several months. As often requested, the upload components now provide notification of uploads from within user interface threads, avoiding unpleasant work for the developer. A new
MultipleUploadSelect component is also available which wraps the Flash-based SWFUpload multiple file upload component. The
MultipleUploadSelect component can be safely used in situations where Flash installation is not a certainty in the intended deployment environment, as the component will fall back to the traditional browser-based upload when Flash is not available. Other new features include the ability to limit global file upload bandwidth for a server, and to programmatically cancel in-progress uploads.

New and improved releases of Echo3 and the Extras component are available now. The big news in this release is the implementation of automatic
WindowPane sizing: the component can now in many cases automatically determine its height based on the size of its content. The demonstration app has been updated to make extensive use of this feature.
WindowPanes additionally now can be positioned from the bottom or right side of a region, and maximize and minimize events are supported for server-side applications. The beta7 version of the Extras library adds only minor bugfixes relative to beta6.
The default Java XML Parser configuration is not secure against untrusted content and allows for XML external entity attacks. This update modifies Echo to include custom parser configuration options to disallow all external XML entities. Much thanks to the SEC Consult Vulnerability Lab for reporting this issue. Updating to the latest version is strongly recommended.
Beta5 is out and available at the usual location.
