OpenLaszlo 4.0.6 is a bugfix release with a few changes since OpenLaszlo 4.0.5. If you are using a version before 4.0.5, we recommending upgrading to 4.0.6. If you are not troubled by the few bugs fixed in 4.0.6, there is no need to upgrade to 4.0.6 right now. 4.0.6 is the recommended release for swf development. You can download it here.

OpenLaszlo 4.0.6 fixed the following bugs:
LPP-4175 - DHTML calendar demo wigs out on opening Event Info
LPP-4731 - reloading browser page causes history to trigger "back" action
LPP-4746 - Javascript errors when using the history mechanism in swf7
LPP-4778 - "LzView#setX(..)" and "LzView#setY(..)" optimization breaks xoffset / yoffset
LPP-4779 - Put under debug flag - version info and init timer from LZPIX
LPP-4857 - dojo.flash.comm errors on firefox os x
LPP-4615 - Override resource declarations
LPP-4793 - Using clonenumber emits warning when using replicator

In general, OpenLaszlo 4.0.6 begins a new strategy, where we intend to offer point releases more frequently to address specific bug fixes. By looking at JIRA, you will see that many bugs are fixed in trunk (4.x), our active development branch. However, we understand that many people aren't comfortable moving to the latest, less stable development branch, so we are going to spin more frequent releases from the 4.0.x branch to provide qualified releases of significant bug fixes more quickly to the community. The next point release is named "Cranberry" and you can view the bug fixes currently scheduled for it on the OpenLaszlo Roadmap in JIRA. You can preview the Cranberry release by downloading of the 4.0.x nightly builds.

Support for DHTML applications remains at "beta" level; it will be fully supported with OL 4.1. Until then, you can find the most recent DHTML bug fixes and support in the trunk branch (4.x nightly builds).

OpenLaszlo 4.0.3 was released to the web today. This is a minor release resolving more than 70 issues reported against OpenLaszlo 4.0.2. Download it here or play with it here (flash runtime) or here here (dhtml runtime).
Full details, including a list of fixed bugs, are available in the Release Notes.
Many of the issues addressed in this release were reported by the OpenLaszlo community, and some of the fixes were contributed by the community. Thanks to everyone who took the time to try out OL4 in SWF or DHTML and report your experiences to the mailing list or forum, and a particularly warm thanks to those of you who filed bugs. This release also has several known bugs in IE7/DHTML, which were discovered just as we were calling the release:

We have fixes in hand for these bugs, which you can get in the legals nightly builds starting at r5785.
Note that while quality continues to improve, we do not recommend 4.0.3 for use in production environments yet, in part due to the known issues listed above. Release 4.1 is the planned milestone at which we will recommend upgrading production deployments from 3.x.

Please report issues to laszlo-dev, file bugs in JIRA, or post questions in the forums.

OpenLaszlo 4.0.2 was released to the web today. This is a minor release resolving almost 50 issues reported against OpenLaszlo 4.0.0, and adding a few new features.

Many of the issues addressed in this release were reported by the OpenLaszlo community. Thanks to everyone who took the time to try out OL4 in SWF or DHTML and report your experiences to the mailing list or forum, and a particularly warm thanks to those of you who filed bugs!

As for features, this release contains support for the <html> tag in SWF, so you can embed raw html content inside your OpenLaszlo app from either support runtime. 4.0.2 also includes preliminary support for the SOAP protocol in DHTML.

Full details are available in the Release Notes.

Note that although recommending OL4 for production deployment is our highest priority, we are not yet there with this release. (See here for more.) Your participation, by reporting your OL4 porting experiences, by filing bug reports, and by directly contributing to the platform, will enormously speed up the process.

You may wonder what happened to 4.0.1. Funny story: just as we were putting 4.0.1 to bed, we found a bad regression in the html wrapper code that was causing high CPU load when running the Amazon demo in DHTML. It turned out to be simpler and safer to quietly release 4.0.1 and turn around a 4.0.2 release in 48 hours than to retract 4.0.1 and rebuild it.

Laszlo Announces Availability of Ajax Runtime

OpenLaszlo 4.0 Sets Industry Standard as First Web Application Development Platform with Cross-Runtime Deployment

SAN MATEO, Calif. and New York, NY (March 20, 2007) – Laszlo Systems, the leading provider of Rich Internet Application (RIA) software, today at the AJAXWorld Conference & Expo East, announced that the latest version of its open source web development platform, OpenLaszlo 4.0, is available for general download at www.openlaszlo.org. OpenLaszlo enables developers to create web-delivered applications that look, feel and act like desktop programs. OpenLaszlo 4.0 is the industry’s first and only RIA platform to support the development and delivery of applications in both Ajax and Flash®, all from a single code base.

“Judging from the quantity of OpenLaszlo 4.0 downloads during the beta period, which are more than double any other release candidate in the company’s history, we are confident that the market is ready and eager for a dependable advanced Ajax solution,” said Jim Grandy, Laszlo’s Director of OpenLaszlo. “With millions of people already touching OpenLaszlo through public websites including those of IBM, Walmart, H&R Block, Monster.com, and Pandora, we expect this new release to only increase the types and number of OpenLaszlo applications available.”

Offered as a free, OSI-certified download to developers, OpenLaszlo is used to build web applications that look, feel and act like desktop software and are accessible through any popular browser. With version 4.0, developers can choose to run OpenLaszlo applications using either Flash or Ajax (natively supported in most browsers), or both. The unique ability of OpenLaszlo to support different runtimes will extend the platform to mobile- and TV-oriented devices in future releases. “By utilizing our runtime independence, enterprises, service providers, and other adopters of OpenLaszlo can be assured that their applications and brands reach the widest possible audience,” said David Temkin, Laszlo’s Co-founder and CTO. “This freedom of deployment was part of our platform architecture from the start, so today marks a significant milestone that will truly set us and our community apart from the competition.”

David Boloker, CTO of Emerging Internet Technology for IBM and primary driver of the OpenAJAX Alliance, added: “OpenLaszlo 4.0 has taken a huge step forward in realizing the vision of combining rich user interfaces with ubiquitous deployment. This announcement will hopefully go far in bringing Ajax to mainstream developers and advancing the new standards-based, platform-agnostic web paradigm.” Downloads and live demonstrations of OpenLaszlo 4.0 applications, along with their source code, are available at www.openlaszlo.org. Laszlo Systems offers a full line of developer training and support services, including subscriptions to the Laszlo Development Network, with individualized developer assistance and other value-added information and tools. More information on developer services and custom solutions from Laszlo Studios can be found at www.laszlosystems.com.

We are excited to announce availability of the fourth snapshot of OpenLaszlo project "Legals". This snapshot showcases a breakthrough in our effort to bring OpenLaszlo to DHTML: we have many of the original OpenLaszlo Components running in DHTML, enough so that it is now feasible to quickly port existing applications from 3.3.x to Legals.

The PR4 snapshot is available from our Downloads page, or directly from Subversion.

To demonstrate what is possible with this snapshot, we have made available DHTML versions of two longstanding OpenLaszlo applications, Calendar and the Components Sampler. These two, and of course LZPIX, are available in Flash and DHTML from the Demos page. As a testament to how well this is going, the port of Calendar from OpenLaszlo 3.3.3 to Legals required changes to less than one percent of the application code.

Once again, please take a close look at Legals; if you are interested in helping to guide the evolution of the web there is no better place to get involved.

We are excited to announce that the snapshot release of the OpenLaszlo Legals project is available! The snapshot represents the current state of the Legals project, the goal of which is to make OpenLaszlo a true multi-runtime environment by supporting DHTML, in addition to SWF. See the OpenLaszlo Legals page for more information.

With this snapshot, you can:

  • Compile and run the LZPIX demo application for both SWF and DHTML with FireFox 1.5 or higher
  • Download binary builds of the Legals software for all supported platforms (Linux/Unix, MacOS X, Windows XP)
  • Access the source code using Subversion, such that you can build and use Legals for simple apps

You will find that most existing OpenLaszlo applications targeted for SWF and built in Legals will function reasonably well. As expected in a preview, there are some new bugs resulting from the significant architecture changes underway to support DHTML. You will also find that there is already a significant amount of functionality for DHTML that is supported. See the Release Notes, available from the OpenLaszlo Download page for specific information. Please keep in mind that the APIs used in Legals will change. We do not guarantee compatibility between this snapshot and the final Legals release.

This is your chance to see what is going on in the project and to get involved! We encourage you to try out this snapshot and report bugs that you find using JIRA. Specific details, as to whether something works in DHTML -vs- SWF is very helpful.

Join the community by getting involved in fixing problems, or supporting functionality in DHTML. See Become a Contributor for information on getting involved.

OpenLazlo 3.3.1 is available now. Download it here.

OpenLaszlo 3.3.1 addresses one issue. There was a single regression, which is that the behavior of simplelayout was inadvertantly broken in OpenLaszlo 3.3. In this release, the behavior of simplelayout has been corrected such that it applies only to a single axis.
