Elasticsearch 2.0.0 is available
Elasticsearch version 2.0.0 has been released.
Based on Lucene 5.2.1, the update adds support for configurable
compression on storage, merges the "query" and "filter" APIs into a
single interface, and allows aggregation operations (such as
moving-average calculations) to be chained together. Also noteworthy
is that the new release runs under the Java Security Manager, which
should provide additional protection against security exploits.
