OpenLaszlo 3.0 released

OpenLaszlo 3.0 released

I am pleased to announce the official release of OpenLaszlo 3.0,
previously known as Laszlo Presentation Server. The new name is in
honor of Laszlo's commitment to its open source platform. Since the
initial release, which allowed folks to download the source in a zip
file, you can now find…

source code access (in subversion)
– open bug tracking
– developer wiki
– active developer mailing lists

Kudos to Oliver, Tucker, Henry, the rest of the Laszlo team, and members of the community for making it happen!

You can downlaod the new release and enjoy the awesome new features. Here are my favorites:

* SOLO (or Standalone Open Laszlo Output) deployment mode that
creates a standalone file that can be used with any web server,
including those that don’t allow an installation of a J2EE servlet. No Laszlo server required.

* Unicode support for source files and datasets. The framework text components also support Unicode editing.

* A drawing API that implements a subset of the WHAT-WG graphics API, enabling JavaScript code to create graphics on the client, on the fly.

* Dynamic libraries that can be used to significantly reduce the initial download size of an OpenLaszlo application.

* Optimizations for Flash Player version 6, with support on over 96%
of consumer browsers, and optimizations and support for the Flash
Player version 7 for even faster performance under managed deployment. Both size and speed improvements — woo hoo!

* Client text optimizations, allowing the use of embedded fonts for total visual control, or HTML-style client fonts for smaller application size and faster text editing.

* Better HTML integration through a resizable canvas allowing
OpenLaszlo applications to be sized proportionally to the enclosing
HTML page. This is really nice and well integrated — you can specify
constraints like width=”${canvas.width-20}”.

* Better JavaScript integration with functions in OpenLaszlo applications making calls to JavaScript in the surrounding HTML page.

* Better navigation capabilities as OpenLaszlo applications can intercept the browser “back” button and use it to move around among program states. Simple API to control history state — see LzHistory for details.

* Laszlo Systems is available to help developers who are using OpenLaszlo via hands-on training courses, technical support, webinars, and consulting to help developers over the periodic hurdles that come up when using a new platform. Laszlo trainings are awesome — you should sign up.

If you haven't already, downlaod OpenLaszlo 3.0!   [Sarah Allen's Weblog]
