The Lucene PMC is pleased to announce the release of Apache Lucene 9.4.1.
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 9.4.1 Release Highlights:
* When reading large segments, the kNN vectors format could fail with a
validation error, preventing further writes or searches on the index. This
bug is now fixed. Only version 9.4.0 was affected, so it is recommended to
skip 9.4.0 if you are using kNN vectors.

Note: The Apache Software Foundation uses an extensive mirroring network for
distributing releases. It is possible that the mirror you are using may not
have
replicated the release yet. If that is the case, please try another mirror.
This also applies to Maven access.
