XX March 2017, Apache Solr 6.5.0 available

Solr is the popular, blazing fast, open source NoSQL search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search and analytics, rich document parsing, geospatial search, extensive REST APIs as well as parallel SQL. Solr is enterprise grade, secure and highly scalable, providing fault tolerant distributed search and indexing, and powers the search and navigation features of many of the world's largest internet sites.

Solr 6.5.0 is available for immediate download at:

 * Pre-start rotation logging is reduced
 * The DirectUpdateHandler2 now implements MetricsProducer and exposes stats via the metrics api and configured reporters.

Streaming:
 * Scoring formula is adjusted for the scoreNodes function
 * Calcite Planner now applies constant Reduction Rules to optimize plans
 * A new significantTerms Streaming Expression that is able to extract the significant terms in an index
 * StreamHandler is now able to use runtimeLib jars
 * Arithmetic operations are added to the SelectStream

UI:
 * It is now possible to delete a shard in the admin UI.

Security:
 * BasicAuthPlugin now supports standalone mode
 * solr.cmd SOLR_SSL_OPTS is now overwritten

SolrCloud:
 * Arbitrary java system properties can be passed to zkcli
 * solr.cloud.wait-for-updates-with-stale-state-pause default is lowered from 7s to 2s in order to reduce the amount of replicas out-of-sync.
 * UpdateRequestProcessors now have a way to guarantee the closing of resources used for a request
 * .system collection is now created on first request if it does not exist

Misc:
 * BlockCache is faster due to less failures when caching a new block

 * MMapDirectoryFactory now supports "preload" option
 * JavaBinCodec now initializes maps and namedLists with known capacity
 * SolrHttpClientBuilder can be configured via java system property

Further details of changes are available in the change log available at: http://lucene.apache.org/solr/6_5_0/changes/Changes.html

Please note, this release cannot be built from source with
Java 8 update 121, use an earlier version instead! This is
caused by a bug introduced into the Javadocs tool shipped
with that update. The workaround was too late for this
Solr release. Of course, you can use the binary
artifacts.

Please report any feedback to the mailing lists (http://lucene.apache.org/solr/discussion.html)

Note: The Apache Software Foundation uses an extensive mirroring network for distributing releases. It is possible that the mirror you are using may not have replicated the release yet. If that is the case, please try another mirror. This also applies to Maven access.
