27 March 2017 - Apache Lucene™ 6.5.0 available
The Lucene PMC is pleased to announce the release of Apache Lucene 6.5.0.

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 contains numerous bug fixes, optimizations, and improvements,
some of which are highlighted below:

  It is now possible filter out duplicates in the NRT suggester
  SimpleQueryString now supports default fuziness
  IndexWriter can return the list of visible field names
  DisjunctionScorer now supports returning the matching children clauses
  A new FunctionScoreQuery that modifies the internal query's score using
the per-document   values
  A new FunctionMatchQuery that returns any documents with a value that
matches a    predicate
  A new WordDelimiterGraphFilter that outputs a correct graph structure for
multi-token expansion at query time
  A new PatternTokenizer that uses Lucene's RegExp implementation
  RangeFieldQuery now supports CROSSES relation
  A new IndexOrDocValuesQuery that uses either an index (points or terms)
or doc values in   order to run a (range, geo box and distance) query,
depending which one is more efficient
  index-time boosts are deprecated
  Term filters are no longer cached
  Compound filters are cached earlier than regular queries
  BKDReader now calls grow on larger increments
  LatLonPointInPolygonQuery are faster
  LatLonPointDistanceQuery now skips distance computations more often
  To-parent block joins now implements two-phase iteration
  Point ranges that match most documents are faster
  PointValues#estimatePointCount is faster with Relation.CELL_INSIDE_QUERY
 Segments are now also sorted during flush, and merging on a sorted index
is substantially faster by using some of the same bulk merge optimizations
that non-sorted merging uses

The release is available for immediate download at:

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.
