Subject [ANNOUNCE] Apache Solr 5.5.0 released
Date Tue, 23 Feb 2016 10:19:24 GMT
23 February 2016, Apache Solr™ 5.5.0 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, dynamic
clustering, database integration, rich document (e.g., Word, PDF)
handling, and geospatial search. Solr is 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 5.5.0 is available for immediate download at:

Please read CHANGES.txt for a full list of new features and changes:

This is expected to be the last 5.x feature release before Solr 6.0.0.

Solr 5.5 Release Highlights:

  * The schema version has been increased to 1.6, and Solr now returns
non-stored doc values fields along with stored fields

  * The PERSIST CoreAdmin action has been removed

  * The <mergePolicy> element is deprecated in favor of a similar
<mergePolicyFactory> element, in solrconfig.xml

  * CheckIndex now works on HdfsDirectory

  * RuleBasedAuthorizationPlugin now allows wildcards in the role, and
accepts an 'all' permission

  * Users can now choose compression mode in SchemaCodecFactory

  * Solr now supports Lucene's XMLQueryParser

  * Collections APIs now have async support

  * Uninverted field faceting is re-enabled, for higher performance on
rarely changing indices

Please report any feedback to the mailing lists

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.
