This is the first full 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 and it's passing the compliance tests for the 5.0 specification. Also of note is that some non-spec additions have been removed from Gemini Management as they have been superseded by new methods in the specification.
