  New features:

    * [LUCY-173] - Bundle Lemon parser generator
    * [LUCY-189] - Bundle utf8proc
    * [LUCY-191] - Unicode normalization
      The new analyzer Lucy::Analysis::Normalizer provides Unicode
      normalization, case folding and stripping of accents.
    * [LUCY-196] - UAX #29 tokenizer
      The new analyzer Lucy::Analysis::StandardTokenizer tokenizes according
      to the UAX #29 word break rules.
    * [LUCY-203] - Implement EasyAnalyzer
      EasyAnalyzer is simple analysis chain using the StandardTokenizer, the
      Normalizer, and the SnowballStemmer.


    * [LUCY-175] - Missing stdarg.h breaks build
    * [LUCY-176] - More INCREF/DECREF symbol collisions under Windows
    * [LUCY-178] - Discriminate between stdio and POSIX in large file support
    * [LUCY-180] - ORQuery, ANDQuery, RequiredOptionalQuery optimizations
                   affect scoring
    * [LUCY-181] - Perl Documentation fix - Remove links to classes within
                   docs, that are not exposed to Perl
    * [LUCY-182] - highlighter bug when searching for duplicate terms [wordX
    * [LUCY-183] - Eliminate spurious "extra" query normalization
    * [LUCY-185] - Improve error handling when required params not supplied
    * [LUCY-186] - Terminate connection from SearchClient properly
    * [LUCY-187] - Adapt to GC changes in Perl 5.15
    * [LUCY-188] - Highlighter should accept weighted Queries (Compilers)
    * [LUCY-193] - Occasional schema file name collision under 'truncate'
    * [LUCY-195] - Revisit pthreads linking on OpenBSD.
    * [LUCY-206] - Work around broken export in Perl 5.15.6


    * [LUCY-142] - Port Clownfish compiler to C

      been removed.

    * [LUCY-134] - Eliminate Parse::RecDescent dependency

  Apache Lucy is an effort undergoing incubation at The Apache Software
  Foundation (ASF), sponsored by the Apache Incubator. Incubation is required
  of all newly accepted projects until a further review indicates that the
  infrastructure, communications, and decision making process have stabilized
  in a manner consistent with other successful ASF projects.  While incubation
  status is not necessarily a reflection of the completeness or stability of
  the code, it does indicate that the project has yet to be fully endorsed by
  the ASF.
