                Release Notes: This release contains numerous bugfixes and improvements since 2.9.3 / 3.0.2, including a memory leak in IndexWriter exacerbated by frequent commits, a file handle leak in IndexWriter when near-real-time readers are opened with compound file format enabled, a rare index corruption case on disk full, NumericRangeQuery / NumericRangeFilter sometimes returning incorrect results with bounds near Long.MIN_VALUE and Long.MAX_VALUE, and various thread safety issues. Lucene 2.9.4 can now also read indexes created by 3.0.x.
