+### m2e.archetype.common changed it structure
+
+_Only relevant for developers of Plug-ins based on m2e_
+
+The single `org.eclipse.m2e.archetype.common` Bundle that used to embed the maven-archetype jars was replaced by a set of multiple bundles, where each corresponds to one of the embedded archetype jars and has reduced OSGi metadata just sufficient for the use with m2e.
+One of those bundles is again named `org.eclipse.m2e.archetype.common` and serves as host bundle for the others, which are fragments to it.
