I have released the final version of the CDK-Taverna 2.0 plug-in yesterday. The plug-in supports Taverna in the latest version 2.3 and the CDK in version 1.3.12. I thank everyone contributing to this project and the developers of such great software libraries and applications like Taverna, the CDK, Weka, IText, JFreeChart and many many more.
The URL for the Taverna plug-in manager is http://www.ts-concepts.de/cdk-taverna2/plugin/.
