Bug fixes
1. LUCENE-1423: InstantiatedTermEnum#skipTo(Term) throws ArrayIndexOutOfBounds on empty index.
(Karl Wettin)
2. LUCENE-1462: InstantiatedIndexWriter did not reset pre analyzed TokenStreams the

(Karl Wettin)
3. LUCENE-1510: InstantiatedIndexReader#norms methods throws NullPointerException on empty index.
(Karl Wettin, Robert Newson)
4. LUCENE-1514: ShingleMatrixFilter#next(Token) easily throws a StackOverflowException
due to recursive invocation. (Karl Wettin)
5. LUCENE-1548: Fix distance normalization in LevenshteinDistance to
not produce negative distances (Thomas Morton via Mike McCandless)
6. LUCENE-1490: Fix latin1 conversion of HALFWIDTH_AND_FULLWIDTH_FORMS
characters to only apply to the correct subset (Daniel Cheng via
Mike McCandless)
7. LUCENE-1576: Fix BrazilianAnalyzer to downcase tokens after
StandardTokenizer so that stop words with mixed case are filtered
out. (Rafael Cunha de Almeida, Douglas Campos via Mike McCandless)
New features
1. LUCENE-1531: Added support for BoostingTermQuery to XML query parser. (Karl Wettin)
2. LUCENE-1435: Added contrib/collation, a CollationKeyFilter
allowing you to convert tokens into CollationKeys encoded usign
IndexableBinaryStringTools. This allows for faster RangQuery when
a field needs to use a custom Collator. (Steven Rowe via Mike
McCandless)
3. LUCENE-1591: EnWikiDocMaker, LineDocMaker, WriteLineDoc can now
read/write bz2 using Apache commons compress library. This means
you can download the .bz2 export from http://wikipedia.org and
immediately index it. (Shai Erera via Mike McCandless)
4. LUCENE-1629: Add SmartChineseAnalyzer to contrib/analyzers. It
improves on CJKAnalyzer and ChineseAnalyzer by handling Chinese
sentences properly. SmartChineseAnalyzer uses a Hidden Markov
Model to tokenize Chinese words in a more intelligent way.
(Xiaoping Gao via Mike McCandless)
5. LUCENE-1676: Added DelimitedPayloadTokenFilter class for automatically adding payloads "in-stream" (Grant Ingersoll)
6. LUCENE-1578: Support for loading unoptimized readers to the
constructor of InstantiatedIndex. (Karl Wettin)
Optimizations
1. LUCENE-1643: Re-use the collation key (RawCollationKey) for
better performance, in ICUCollationKeyFilter. (Robert Muir via
Mike McCandless)
