Manticore Search 10.1.0: Prometheus Integration, Enhanced Monitoring, and Major Improvements

We’re excited to announce the release of Manticore Search 10.1.0 , featuring updates from May 2025, bringing built-in Prometheus integration, enhanced monitoring capabilities, and numerous stability improvements to make your search experience more reliable and efficient.

⚠️ Important Notice

Starting with version 10.1.0, CentOS 7 is no longer supported. We recommend upgrading to a supported operating system to maintain compatibility and security. Support for RHEL 10-based systems is currently in development.

🛠️ New Features and Improvements

This release includes several significant enhancements:

Built-in Prometheus Exporter ( Issue #537 ): Added built-in support for exporting Prometheus metrics, making it easier to monitor and understand your search system. This feature was previously available only as a separate project: https://github.com/manticoresoftware/manticoresearch-prometheus .
KNN Index Management ( Issue #3409 ): Added ALTER TABLE tbl REBUILD KNN command for easier migration of KNN indexes between versions.
Enhanced Cluster Recovery ( Issue #1894 ): Improved cluster recovery with periodic seqno saving for faster node restart after crashes.
