This patch release contains an important fix for a bug affecting version 9.4.1. The release is available for immediate download at:

Lucene 9.4.2 Release Highlights
Bug fixes
- Fixed integer overflow when opening segments containing more than ~16M KNN vectors.
- Fixed cost computation of BitSets created via DocIdSetBuilder, such as for multi-term queries. This may improve performance of multi-term queries.
Enhancements
- CheckIndex now verifies the consistency of KNN vectors more thoroughly.
