Welcome to This Week in Elasticsearch and Apache Lucene! With this new weekly series, we're bringing you an update on all things Elasticsearch and Apache Lucene at Elastic, including the latest on commits, releases and other learning resources.
We'll be deprecating our Rivers feature for Elasticsearch. You can read the full details, including recommendations for replacing your own Rivers plugins, in Shay Banon's blog post.

Elasticsearch Plugin Releases
We had several plugin release in this past week. You can find more information about the updates in
- River plugins: CouchDB v 2.5.0, RabbitMQ v 2.5.0, Twitter v 2.5.0, Wikipedia v 2.5.0
- Transport plugins: Memcached transport v 2.5.0, Servlet transport v 2.5.0 and Thrift transport v 2.5.0.
And let's not forget the Mapper Attachment plugin, also released as version 2.5.0.
You can find full details in the release notes for each plugin as sent to the Elasticsearch User mailing list.
- 5.1.0 release may be coming soon.
- PrefixQuery now extends AutomatonQuery and PrefixTermsEnum is removed. This is in preparation for auto-prefix terms.
- Simplify TwoPhaseIterator by passing the approximation to the constructor.
- FST.save could write a corrupted FST because it didn't flush/close the BufferedOutputStream first.
- Lucene continuously tests Java early access builds, and uncovered a new Java 1.9 bug which we've worked around. Elasticsearch's sources were also affected.
- A new near-real-time, document based suggester is coming to Lucene, factored out of Elasticsearch's completion suggester.
- Span queries will soon support approximations so they are more efficient handling conjunctions of multiple span queries.
- More efficient query-time joins based on global ordinals is coming, derived from Elasticsearch's join implementations.
