Version 13.2.3

Released: July 8th 2025

Blogpost: https://manticoresearch.com/blog/manticore-search-13-2-3/

This version focuses on making Vector Search faster, more memory-efficient, and better suited for large-scale data, while also improving compatibility and stability.

Breaking Changes

• ⚠️ v13.0.0 Updated the KNN library API to support empty float_vector values. This update doesn’t change the data format but does increase the Manticore Search / MCL API version.
• ⚠️ v12.0.0 PR #3516 Fixed a bug with incorrect source and destination row IDs during KNN index training and building. This update doesn’t change the data format but increases the Manticore Search / MCL API version.
• ⚠️ v11.0.0 Added support for new KNN vector search features like quantization, rescoring, and oversampling. This version changes the KNN data format and the KNN_DIST() SQL syntax. The new version can read older data, but older versions won't be able to read the new format.
