Elasticsearch Plug-in 2.1.1

This release note applies to the 2.1.1 version of the Elasticsearch Transport Plug-in (September 2015). It adds compatibility with newer Elasticsearch versions up to 1.7.x, multiple new features, and quite a few bug fixes, including several that solve issues found in 2.1.0.
