@ -174,6 +174,10 @@ Changes in backwards compatibility policy
* LUCENE-3396: ReusableAnalyzerBase.TokenStreamComponents.reset(Reader) now returns void instead
of boolean. If a Component cannot be reset, it should throw an Exception. (Chris Male)
* LUCENE-3396: ReusableAnalyzerBase has been renamed to Analyzer. All Analyzer implementations
must now use Analyzer.TokenStreamComponents, rather than overriding .tokenStream() and
.reusableTokenStream() (which are now final). (Chris Male)
Changes in Runtime Behavior
* LUCENE-2846: omitNorms now behaves like omitTermFrequencyAndPositions, if you

@ -517,3 +517,8 @@ If you did this before (bytes is a byte[]):
you can now do this:
new BinaryField("field", bytes)
* LUCENE-3396: Analyzer.tokenStream() and .reusableTokenStream() have been made final.
It is now necessary to use Analyzer.TokenStreamComponents to define an analysis process.
Analyzer also has its own way of managing the reuse of TokenStreamComponents (either
globally, or per-field). To define another Strategy, implement Analyzer.ReuseStrategy.
