Features

Native support for the maxsim operator and efficient indexing inspired by XTR-WARP project. This makes it possible to build ColBERT- or ColPaLI-style multi-vector retrieval applications seamlessly within PostgreSQL.

Improvements

• More KMeans parameters can be configured
• Better progress report for internal KMeans build
