Lire 1.0b4 released

In the wake of integrating Lire in Solr 6.3 and updating it to Java 8, we put a milestone online: Lire 1.0 beta 4. Extending on the last version released (beta 2) it has now a more robust implementation of the metric spaces plugin, there is a new extraction tool, which stores extracted features as Base64 encoded strings along with an indexing tool that can read them and add hashes for faster search. As outlined in the last post, Gradle is now the main build system, which makes using Lire for development a whole lot easier.
