@ -117,11 +117,50 @@ New Features
* LUCENE-6077: Added a filter cache. (Adrien Grand, Robert Muir)
* LUCENE-6088: TermsFilter implements Accountable. (Adrien Grand)
Optimizations
* LUCENE-5960: Use a more efficient bitset, not a Set<Integer>, to
track visited states. (Markus Heiden via Mike McCandless)
* LUCENE-5959: Don't allocate excess memory when building automaton in
finish. (Markus Heiden via Mike McCandless)
* LUCENE-5963: Reduce memory allocations in
AnalyzingSuggester. (Markus Heiden via Mike McCandless)
* LUCENE-5938: MultiTermQuery.CONSTANT_SCORE_FILTER_REWRITE is now faster on
queries that match few documents by using a sparse bit set implementation.
(Adrien Grand)
* LUCENE-5969: Refactor merging to be more efficient, checksum calculation is
per-segment/per-producer, and norms and doc values merging no longer cause
RAM spikes for latent fields. (Mike McCandless, Robert Muir)
* LUCENE-5983: CachingWrapperFilter now uses a new DocIdSet implementation
called RoaringDocIdSet instead of WAH8DocIdSet. (Adrien Grand)
* LUCENE-6022: DocValuesDocIdSet checks live docs before doc values.
(Adrien Grand)
* LUCENE-6030: Add norms patched compression for a small number of common values
(Ryan Ernst)
* LUCENE-6040: Speed up EliasFanoDocIdSet through broadword bit selection.
(Paul Elschot)
* LUCENE-6033: CachingTokenFilter now uses ArrayList not LinkedList, and has new
isCached() method. (David Smiley)
* LUCENE-6031: TokenSources (in the default highlighter) converts term vectors into a
TokenStream much faster in linear time (not N*log(N) using less memory, and with reset()
implemented. Only one of offsets or positions are required of the term vector.
(David Smiley)
* LUCENE-6089, LUCENE-6090: Tune CompressionMode.HIGH_COMPRESSION for
better compression and less cpu usage. (Adrien Grand, Robert Muir)
* LUCENE-6088: TermsFilter implements Accountable. (Adrien Grand)
API Changes
* LUCENE-5900: Deprecated more constructors taking Version in *InfixSuggester and

modules. (Ramkumar Aiyengar, Uwe Schindler)
