API Changes
* LUCENE-3606: IndexReader will be made read-only in Lucene 4.0, so all
methods allowing to delete or undelete documents using IndexReader were
deprecated; you should use IndexWriter now. Consequently
IndexReader.commit() and all open(), openIfChanged(), clone() methods
taking readOnly booleans (or IndexDeletionPolicy instances) were
deprecated. IndexReader.setNorm() is superfluous and was deprecated.
If you have to change per-document boost use CustomScoreQuery.

* LUCENE-3606: FieldNormModifier was deprecated, because IndexReader's
setNorm() was deprecated. Furthermore, this class is broken, as it does
not take position overlaps into account while recalculating norms.
