When we started releasing jbossws integration with Metro and CXF, the release major number was increased, thus we had 3.0.1. The native stack was previously meant to be named 2.0.4, so we used the double naming. We later decided to drop the double naming because it seemed too confusing and went on using the same name versioning for each stack integration.
