OpenLaszlo 4.1.1 (Recommended release for both SWF/Flash and DHTML/Ajax Development)
OpenLaszlo 4.1.1 is a major release bringing full support for both the DHTML/Ajax and the SWF/Flash platforms. It also includes over 800 bug fixes and a significantly improved documentation suite.
OpenLaszlo 4.1.1 has been fully-qualified across the following browser/platform combinations: Safari3/OSX, Firefox2/OSX, Internet Explorer 7/WinXP, Firefox 2/WinXP, and Firefox 2/Linux. We have tested the full suite of demos, samplers, and example applications with the requirement that, when possible, DHTML applications behave the same as their SWF counterparts.
OpenLaszlo 4.1.1 is now the recommended release for all developers on all platforms, and current users of OL 3.x and 4.0 should investigate upgrading to this new release.
OpenLaszlo 4.1.1 fixes many bugs in the initial 4.1.0 release. A list of the bugs fixed in OpenLaszlo 4.1.1 and details about each can be found here: Fixed bugs in 4.1.1
We recommend that all users who downloaded OpenLaszlo 4.1.0 upgrade to release 4.1.1.

Software Packaging Information
OpenLaszlo software is available for download in the following configurations. (Versions of the OpenLaszlo platform prior to OpenLaszlo 3.0 were called the Laszlo Presentation Server or LPS.)
- Development Kits for Windows, Mac, Linux, and Unix: These packages are binary distributions with installers for specific platforms and include the Tomcat 5.0.24 servlet container. Development kits also include the documentation, sample code, demonstrations, and Laszlo in 10 minutes tutorial code.
- Development Kit for Any OS: This package is a development kit without the Tomcat servlet container. Choose this package if you wish to deploy OpenLaszlo into an existing Java Application Server or in your own servlet container, such as IBM WebSphere or JBoss.
- Servlet Only: This package contains only the servlet, the smallest set of files required to deploy an OpenLaszlo application on any OS running Java.
- Source Code Distribution: This package provides all of the source code, docs, examples, and supporting collateral necessary to build OpenLaszlo. Use this distribution to extend OpenLaszlo, customize it for your application, and to contribute to the OpenLaszlo project.
OpenLaszlo (and previous LPS release versions 2.2 or higher) are released under the Common Public License (Version 1.0).
The third party software components that are distributed with OpenLaszlo (and LPS) are released under their own license terms and conditions. OpenLaszlo also provides system requirements and certified application server environments to ensure a successful deployment.
