+
+The Lucene PMC is pleased to announce the release of Apache Lucene 9.5.0.
+
+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 9.5.0 Release Highlights:
+
+#### New features
+
+ * Added KnnByteVectorField and ByteVectorQuery that are specialized for indexing and querying byte-sized vectors. Deprecated KnnVectorField, KnnVectorQuery and LeafReader#getVectorValues in favour of the newly introduced KnnFloatVectorField, KnnFloatVectorQuery and LeafReader#getFloatVectorValues that are specialized for float vectors.
+ * Added IntField, LongField, FloatField and DoubleField: easy to use numeric fields that perform well both for filtering and sorting.
+ * Support for Java 19 foreign memory access ("project Panama") was enabled by default removing the need to provide the "--enable-preview" flag.
+ * Added ByteWritesTrackingDirectoryWrapper to expose metrics for bytes merged, flushed, and overall write amplification factor.
+
+#### Optimizations
+
+* Improved storage efficiency of connections in the HNSW graph used for vector search
+* Added  new stored fields and term vectors interfaces: IndexReader#storedFields and IndexReader#termVectors. These do not rely upon ThreadLocal storage for each index segment, which can greatly reduce RAM requirements when there are many threads and/or segments.
+* Several improvements were made to IndexSortSortedNumericDocValuesRangeQuery including query execution optimization with points for descending sorts and BoundedDocIdSetIterator construction sped up using bkd binary search.
+S
+#### Other
+
+* Moved DocValuesNumbersQuery from sandbox to NumericDocValuesField#newSlowSetQuery
+* Fix exponential runtime for nested BooleanQuery#rewrite with non scoring clauses
