Build
- * LUCENE-2117: SnowballAnalyzer now holds a runtime-dependency on

- (Robert Muir via Simon Willnauer)
-
* LUCENE-2124: Moved the JDK-based collation support from contrib/collation
into core, and moved the ICU-based collation support into contrib/icu.
(Steven Rowe, Robert Muir)
+ * LUCENE-2226: Moved contrib/snowball functionality into contrib/analyzers

{@link org.apache.lucene.analysis.TokenFilter} and {@link
org.apache.lucene.analysis.Analyzer} implementations that use Snowball
stemmers.
+
+This project provides pre-compiled version of the Snowball stemmers
+based on revision 500 of the Tartarus Snowball repository,
+together with classes integrating them with the Lucene search engine.
+
+
+A few changes has been made to the static Snowball code and compiled stemmers:
+
+
+ - Class SnowballProgram is made abstract and contains new abstract method stem() to avoid reflection in Lucene filter class SnowballFilter.
+ - All use of StringBuffers has been refactored to StringBuilder for speed.
+ - Snowball BSD license header has been added to the Java classes to avoid having RAT adding ASL headers.
+
+
+See the Snowball home page for more information about the algorithms.
+
+
+
+IMPORTANT NOTICE ON BACKWARDS COMPATIBILITY!
+
+
+An index created using the Snowball module in Lucene 2.3.2 and below
+might not be compatible with the Snowball module in Lucene 2.4 or greater.
