+
+The Lucene PMC is pleased to announce the release of Apache Lucene 9.3.0.
+
+Apache Lucene is a high-performance, full-featured search engine library written entirely in Java. It is a technology suitable for nearly any application that requires structured search, full-text search, faceting, nearest-neighbor search across high-dimensionality vectors, spell correction or query suggestions.
+
+This release contains numerous bug fixes, optimizations, and improvements, some of which are highlighted below. The release is available for immediate download at:
+
+  <https://lucene.apache.org/core/downloads.html>
+
+### Lucene 9.3.0 Release Highlights:
+
+ * Merge on full flush is enabled now by default with a timeout of 500ms, giving the merge policy a chance to merge NRT segments together before publishing a new point-in-time view of the IndexReader. This should give queries a small performance boost in the near-realtime case, especially terms-dictionary-intensive queries like fuzzy queries.
+ * Add getAllChildren functionality to facets.
+ * Added facetsets module for high dimensional (hyper-rectangle) faceting. 
+ * Top-level two-clause disjunctions sorted by score now use the block-max MAXSCORE algorithm, which introduced a 40%-75% speedup in our benchmarks.
+ * BooleanQuery can return quick counts for simple boolean queries.
+ * When running KnnVectorQuery with a filter, reuse the cached filter bit set.
