The Lucene PMC is pleased to announce the release of Apache Lucene 8.1.0.

Apache Lucene is a high-performance, full-featured text search engine
library written entirely in Java. It is a technology suitable for
nearly any application that requires full-text search, especially
cross-platform.

This release contains numerous bug fixes, optimizations, and
improvements, some of which are highlighted below. The release is
available for immediate download at:

http://lucene.apache.org/core/mirrors-core-latest-redir.html

Lucene 8.1.0 Release Highlights:

 * A query introspection API has been introduced.
 * Luke, well-known GUI for inspecting Lucene indexes, now added as a
Lucene module
 * Merging dimensional points to use radix partitioning, which has
also been optimized
 * Bugfix: LatLonShapePolygonQuery returns incorrect WITHIN results
with shared boundaries
 * TieredMergePolicy#findForcedMerges now tries to create the cheapest merges
 * Build point writers in the BKD tree only when they are needed
 * SynonymQuery can now deboost the document frequency of each term
when blending synonym scores
 * ConstantScoreQuery can early terminate if minimum score > constant
score (total hits are not requested)
 * DateRangePrefixTree can now parse more precise dates
