OpenLaszlo 4.6.1 also contains two significant improvements from community contributors. Sebastian Wagner extended the output of RPC with Gson as the marshaller for JSON. More details are provided in Bug LPP-8437, including how to write your own marshaller and how to get the Gson Factory to set your custom marshalling options. Raju Bitter added support for rotation in DHTML using FireFox 3.5, and fixed the default rotation origin to be top left or 0% for DHTML. See BUG LPP-8362 for more details. A complete list of bugs fixed in this release can be viewed here.

For those of you who have already upgraded your applications to OpenLaszlo 4.2 or higher, no further work is needed. You should just start using OpenLaszlo 4.6.1.

We would like to thank the entire OpenLaszlo community for submitting bug fixes and participating in discussions to help make OpenLaszlo a better platform. Special thanks to André Bargull and Raju Bitter for their continued and amazing support of the project. We'd also like to thank the incredible engineering team at G.ho.st, who have worked with us as a sponsor to bring SWF9 and many other improvements to the community. Special recognition is also due to community contributors: Chad Lancour, Rami Ojares, Philip Romanik, and Jason Gratt.

For more details, please see the Release Notes.

To make sure you have the proper release, check the build number in Laszlo Explorer. It should report r8678.

If you are using an earlier version, we recommending upgrading to 4.0.12, which is the recommended release for swf development. Support for applications to DHTML remains at "beta" level; it will be fully supported with OL 4.1.

• [LPP-5321] - Serious memory leak for CSS styled nodes

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 4.0.7 fixes the following bugs:

LPP-1636 - Scripts do not handle spaces in path names
LPP-2593 - Trunk: lzc and lzc.bat will not run in a standard Windows configuration
LPP-4099 - Can't get onerror event while loading resources from 403 forbidden image links
LPP-4142 - LZC arguments that use an equal sign (such as --runtime=swf8) do not work on the Windows command line (cmd).
LPP-4664 - test/explicit-replicators/replicator.lzx visually deletes last two items when the second-to-last item is clicked and ...
LPP-4719 - Provide a way to output relevant debug info to copy/paste into mail
LPP-4737 - Empty graphic seen when you navigate to the OL app without Flash

LPP-4843 - Error parsing arguments to lzc using native Windows
LPP-4844 - ondata event not triggered when dataset loads v4.0.5 SWF
LPP-4884 - All small applications, except weather, will fail to display in IE7/swf.
LPP-4906 - Laszlo Explorer, incorrect text
LPP-4999 - IE resets history to #0 after visiting another site and pressing the back button

LPP-5012 - Multiple calls to callJS fails in Firefox
LPP-5016 - _parse gets called before canvas is initialized
LPP-5070 - Videos not playing in YouTube demo

OpenLaszlo 4.0.7 has the following improvement:
The bugReport method of the Debugger can be used to create a report suitable for copy/pasting into a bug report. To use it, enable backtraces and debugging, then inspect the error message that you believe reveals a bug, then invoke Debug.bugReport() in the debugger. Copy and paste the output of that call into your bug report. This process is described in more detail in the Debugging chapter of the OpenLaszlo Developer's Guide.

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 4.0.6 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-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 4.0.5 is the recommended platform for .swf development. With OpenLaszlo 4.0.5, there is no longer any reason to continue application development using OpenLaszlo 3.4. This release has been qualified the Laszlo Systems Quality Assurance team and users in the community. Over 100 improvements have been made since OpenLaszlo 4.0.3, including
fixes from community members and the OpenLaszlo team.

In addtion, OpenLaszlo 4.0.5 added a new feature: explicit replication, which enables data-driven replication as an explicit syntax tag in LZX. You can read more about it in the proposal on the wiki: http://wiki.openlaszlo.org/Explicit_Replication. There will be more detailed documentation in upcoming releases.

And, for those of you following the releases closely - What happened to version 4.0.4? We skipped a number. We don't like 404s.

Keep in mind that support for applications to DHTML remains at "beta" level; it will be fully supported with OL 4.1 (code name RingDing in Jira). You can see the latest and greatest by downloading the nightly builds of 4.x trunk at http://www.openlaszlo.org/download.

For every release, we rely on the OpenLaszlo community to help ensure the quality of the platform release and to participate in determining its future direction. We encourage you to report any problems, and to make suggestions for enhancements, through our JIRA bug tracking system.

Thank you all for your efforts towards making OpenLaszlo 4.0.5 our officially recommended SWF platform.

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:

• Views clip their contents when opacity changed in IE7 DHTML This an issue with the IE7 renderer. The workaround is to not set the width/height of the container that has alpha (so the view system can resize it to its contents) or set the width/height to be bigger than its contents. See the JIRA bug comments for an example of this workaround, and this msdn article.
• LPP-4242 Controls go to disabled state when outer view opacity set in IE7 DHTML
• LPP-4244 Mouse handling busted in IE7 DHTML

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.
