OpenLaszlo 4 is out, you rock stars!

From the brilliant post on the OpenLaszlo project blog (man, that is a well-written blog entry! Wonder if there was a ghost writer involved?)

We are extremely pleased and proud to announce that OpenLaszlo 4.0 is now available. This is the first official release of the new multi-runtime edition of OpenLaszlo, complete with a native browser DHTML (“ajax”) runtime, a heavily revamped Flash (7, 8, 9) runtime, and much more. With OpenLaszlo 4.0, you can compile source LZX applications for any supported target with a single mouse click.

This release of OpenLaszlo is built on a new kernel architecture that abstracts away platform differences. Also, with OL4, we have switched to an inheritance-based class system that tracks the emerging ECMAScript 4 standard. These new language features have been implemented in the LFC core to support (and extend) JavaScript 2 `class` declarations portably. This means that the OpenLaszlo platform is well engineered to keep up with emerging JavaScript standards and to support new target runtimes.

In addition to literally hundreds of improvements to all aspects of the platform software and documentation, we have added new features, such as support for streaming media. The documentation tools have been re-implemented in order to to make them easier to maintain and also to give us more possibilities for arranging and accessing the data in the Reference Manual. Eventually, this will allow us to provide better cross-referencing, better indexing, more user control over presentation of information, and more options for printing and displaying the documentation.

We have put a lot of effort into improving our open source processes. The tools we use to build, test, and analyze OpenLaszlo have matured significantly with OL4. We have changed to using Subversion, for source control, in order to enable a more open development process. The build is now based on ant 1.6.5, rather than ant 1.5. We have created a new testing tool, lztest, for automated testing, to complement lzunit, our tool for application- and component-level testing. We have created a suite of benchmarks and benchmark analysis tools. By any criterion, this is the most ambitious and significant release in the history of OpenLaszlo.

The OpenLaszlo project aspires to be truly open and inclusive. Raju Bitter, our OpenLaszlo community manager, is on board to answer questions, streamline processes, and generally make it easier for you to play a vital part in this platform’s success.
Post questions and comments to laszlo-user@openlaszlo.org or to the OpenLaszlo Forum. Please report bugs, especially regressions from OpenLaszlo 3.x, to our bug database.

OpenLaszlo 4.0 is the culmination of a project that began more than a year ago, and it embodies the contributions of dozens of community members from around the world. Thank you, and congratulations to all of us!
