The Lucene PMC is pleased to announce the release of Apache Lucene 9.6.0. 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 9.6.0 Release Highlights: * Introduce a new KeywordField for simple and efficient filtering, sorting and faceting. * Add support for Java 20 foreign memory API.
