+March 2011, Lucene 3.1 available
+The Lucene PMC is pleased to announce the release of Apache Lucene 3.1.
+
+This release contains numerous bug fixes, optimizations, and
+improvements, some of which are highlighted below.  The release
+is available for immediate download at http://www.apache.org/dyn/closer.cgi/lucene/java.
+See the CHANGES.txt
+file included with the release for a full list of details.
+
+Lucene 3.1 Release Highlights
+
+* Numerous performance improvements: faster exact PhraseQuery;
+ natural segment merging favors segments with deletions; primary
+ key lookup is faster; IndexWriter.addIndexes(Directory[]) uses
+ file copy instead of merging; Several Directory performance improvements;
+ compound file is dynamically turned off for large
+ segments; fully deleted segments are dropped on commit; faster
+ snowball analyzers (in contrib); ConcurrentMergeScheduler is more
+ careful about setting priority of merge threads.
+
+* ReusableAnalyzerBase make it easier to reuse TokenStreams correctly
+
+* Improved Analysis capabilities: Improved Unicode support, including Unicode 4,
+more friendly term handling (CharTermAttribute), easier object reuse and better
+support for protected words in lossy token filters (e.g. stemmers)
+
+
+* ConstantScoreQuery now allows directly wrapping a Query
+
+* IndexWriterConfig.setMaxThreadStates for controls of IndexWriter threads
+
+* IndexWriter is now configured with a new separate builder API
+ (IndexWriterConfig).
+
+* IndexWriter.getReader is replaced by
+ IndexReader.open(IndexWriter).  In addition you can now specify
+ whether deletes should be resolved when you open an NRT reader.
+
+* MultiSearcher is deprecated; ParallelMultiSearcher has been
+ absorbed directly into IndexSearcher
+
+* On 64bit Windows and Solaris JVMs, MMapDirectory is now the
+ default implementation (returned by FSDirectory.open).
+ MMapDirectory also enables unmapping if the JVM supports it.
+
+* New TotalHitCountCollector just counts total number of hits
+
+* ReaderFinishedListener API enables external caches to evict
+ entries once a segment is finished
+
