27 November 2011, Apache Solr™ 3.5.0 available
The Lucene PMC is pleased to announce the release of Apache Solr 3.5.0.

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 contains numerous bug fixes, optimizations, and
improvements, some of which are highlighted below.  The release
is available for immediate download at:

details.
