Release Announcement

22 July 2012, Apache Solr™ 3.6.1 available
The Lucene PMC is pleased to announce the release of Apache Solr 3.6.1.

Solr is the popular, blazing fast open source enterprise search platform from
the Apache Lucene project. Its major features include powerful full-text
search, hit highlighting, faceted search, dynamic clustering, database
integration, rich document (e.g., Word, PDF) handling, and geospatial search.
Solr is highly scalable, providing distributed search and index replication,
and it powers the search and navigation features of many of the world's
largest internet sites.

This release is a bug fix release for version 3.6.0. It contains numerous
bug fixes, optimizations, and improvements, some of which are highlighted
below.  The release is available for immediate download at:
   http://lucene.apache.org/solr/mirrors-solr-3x-redir.html (see
note below).

See the CHANGES.txt file included with the release for a full list of
details.

Solr 3.6.1 Release Highlights:

 * The concurrency of MMapDirectory was improved, which caused
   a performance regression in comparison to Solr 3.5.0. This affected
   users with 64bit platforms (Linux, Solaris, Windows) or those
   explicitely using MMapDirectoryFactory.

 * ReplicationHandler "maxNumberOfBackups" was fixed to work if backups are
   triggered on commit.

 * Charset problems were fixed with HttpSolrServer, caused by an upgrade to
   a new Commons HttpClient version in 3.6.0.

 * Grouping was fixed to return correct count when not all shards are
   queried in the second pass. Solr no longer throws Exception when using
   result grouping with main=true and using wt=javabin.

 * Config file replication was made less error prone.

 * Data Import Handler threading fixes.

 * Various minor bugs were fixed.

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 goes for Maven access.

Happy searching,

Lucene/Solr developers
