OpenCms 6.0 alpha 3 released

December 21, 2004

Alkacon Software has finished work on the third public binary alpha release of OpenCms 6.0. OpenCms 6.0 is a major upgrade, and it vastly expands the features of OpenCms 5.0.

This alpha 3 release improves the features of the new XML content and adds support for Java 1.5

When will the "final" release of OpenCms 6.0 be available?

We now do expect the final release of OpenCms 6.0 end of Q1 2005. You can help speeding up the process of development by providing feedback for this release and the following releases, especially regarding bugs. In case you find any bug, please use the OpenCms bugzilla to document it. The more feedback and code contributions are made, the faster we can fix the issues and finish the development.

Who should use this 6.0 alpha 3 version?

This is an alpha version. Please don't expect it to be perfectly stable. One of the most important Open Source philosophies is "Release early, Release often", and this is what we intend to do with this and subsequent 6.0 releases. If and how you should use this version depends on what your goals are:

• If you are currently using any previous 6.0 development release (e.g. 6.0 alpha 1 or alpha 2), you should upgrade to this new version.
• If you are an IT professional or a company working with OpenCms on a regular basis, you should definitely check if and how your current websites, modules and functions can be ported to the new release. Even though changes on the Java API level and changes on the DB schema are to be expected until we reach the beta or even release candidate state of the development, most of the big changes have already been made.
• If you start a new project that is expected to go live in about 3 months, you may use this version to build your project - but be prepared for some extra work to update when new releases become available, and also for some time figuring out the so far undocumented features if these are required.
• If you are working on a project with OpenCms 5.0.x that has a delivery date soon, you should stick to the 5.0.x version unless you absolutely require a feature of the 6.0 version.
• If you are running a website based on OpenCms, and you plan to implement some new features in the not so far future, you should install this version on a test machine and check out the new features.

TODO list to be finished before OpenCms 6.0 is released:

• The OpenCms workplace is still not fully implemented in JSP - all XmlTemplate using dialogs will be rewritten to JSP
• More of the configuration will be transferred from opencms.properties to the new Digester XML based configuration file, the current opencms.properties will stay only for the database configuration - this configuration will be moved to the XML in a release after 6.0.
• The most important management functions (e.g. cache maintainance, system status) will be exposed to allow JMX containers to manage OpenCms
• Documentation needs to be revised for old functions and written for new functions
• Testing and bug fixing - your feedback is required!
• The development of the Content Releationship Engine (CRE) initially scheduled for the 6.0 release has been moved to a version past the 6.0 release.  

The team at Alkacon Software - The OpenCms Experts wants to thank everyone who has contributed to this release of OpenCms.
