This release is intended for people who dont have a pre installed Java Runtime environment. If you are not sure if this may apply to you or you do not know what a Java Runtime Environment is, you are on the safe side with this release.
The new release of Caliph & Emir 0.9.16 brings some major changes under the hood for Emir: The retrieval of graph based semantic information is now powered by a path index implemented with Lucene. Anonymous (wildcard) nodes are allowed, they can be used by typing an * as a node label in the graph query editor. In the result list images can be previewed by clicking on the thumbnails. The installers GUI is now more neat (and orange) and checks if Java is installed. The windows launchers now have icons and the 2-dimensional visualization has been tweaked a bit to look smoother. Additionally libraries were updated and log4j was added.
