it's the same. we added jPDL to the name to mark the difference between jBPM as the platform for process languages and jPDL as one package with all tools and components for the jPDL language. The same way we will be packaging a jbpm-bpel engine as well.
Thank you Tom
Some of tools and components for the jPDL language are also included in the gpd 3.0.12?
what do you mean by 'some tools' The GPD did not change (well it did, but mostly below the surface)
