Lucene 3.6.1 was released on July 22, 2012
22 July 2012, Apache Lucene™ 3.6.1 available The Lucene PMC is pleased to announce the release of Apache Lucene 3.6.1. Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It is a technology suitable for nearly any application that requires full-text search, especially cross-platform. 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/core/mirrors-core-3x-redir.html (see note below). See the CHANGES.txt file included with the release for a full list of details. Lucene 3.6.1 Release Highlights: * The concurrency of MMapIndexInput.clone() was improved, which caused a performance regression in comparison to Lucene 3.5.0. * MappingCharFilter was fixed to return correct final token positions. * QueryParser now supports +/- operators with any amount of whitespace. * DisjunctionMaxScorer now implements visitSubScorers(). * Changed the visibility of Scorer#visitSubScorers() to public, otherwise it's impossible to implement Scorers outside the Lucene package. This is a small backwards break, affecting a few users who implemented custom Scorers. * Various analyzer bugs where fixed: Kuromoji to not produce invalid token graph due to UNK with punctuation being decompounded, invalid position length in SynonymFilter, loading of Hunspell dictionaries that use aliasing, be consistent with closing streams when loading Hunspell affix files. * Various bugs in FST components were fixed: Offline sorter minimum buffer size, integer overflow in sorter, FSTCompletionLookup missed to close its sorter. * Fixed a synchronization bug in handling taxonomies in facet module. * Various minor bugs were fixed: BytesRef/CharsRef copy methods with nonzero offsets and subSequence off-by-one, TieredMergePolicy returned wrong-scaled floor segment setting. 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, Apache Lucene/Solr Developers
