Improvements
- Allow easier configuration of the Panama vectorization provider with newer Java versions. Set the org.apache.lucene.vectorization.upperJavaFeatureVersion system property to increase the set of Java versions that Panama vectorization will provide optimized implementations for.
Bug fixes
- Fixed backwards compatibility bug that caused sparse (not all documents have a vector) KNN indices written with 9.0.0 to give silently (no exception) terrible recall results when searched by any 9.x release
- Improve Tessellatorlogic when two holes share the same vertex with the polygon which was failing in valid polygons.
- Fix backwards compatibility bug that caused 9.12.0 to incorrectly throw IllegalStateException when trying to open an IndexReader on an index created with quantized (int4, int7, int8) KNN vectors using Lucene99HnswScalarQuantizedVectorsFormat.
