This is the first release of Gemini Management for the 2.0.x line. The major theme for the 2.0.x line is compatibility with the Enterprise OSGi 5.0 specification. Gemini Management now includes and re-exports the 'org.osgi.jmx' packages from the 5.0 specification but it's compliance against the specification has not yet been checked. Also of note is that some non-spec additions have been removed from Gemini Management as they have been superseded by new methods in the specification.
