March 2025 performance summary for grafana/grafana: Delivered major Unified Storage improvements across search, provisioning, and observability. Implemented a substring-aware search analyzer and refined not-in handling, plus tests and results sorted by relevance and title, boosting search accuracy. Improved dashboard provisioning reliability by ensuring deleted dashboards update the indexer, reducing unnecessary indexer waits, and added a dashboard_tag index to accelerate tag queries. Enhanced observability with tracing spans and debug logging for listAtRevision and updated documentation for search API and load tests. These changes deliver faster, more accurate user searches, quicker provisioning at scale, and clearer diagnostics, aligning with growth in usage and data volume.

February 2025 monthly summary for grafana/grafana: Delivered key observability enhancements and a critical pagination fix, improving performance monitoring, reliability, and user experience. Focused on business value by enabling faster diagnosis and stable dashboard results.

January 2025 focused on strengthening Unified Storage security, boosting search capabilities, and improving observability and maintainability in grafana/grafana. Key configuration enhancements were delivered for Unified Storage with new CA certificate path configuration and an option to skip HTTPS certificate verification, enabling enterprise-grade certificate management and safer storage configuration. Dashboard search and sorting were enhanced with full-field search across dashboards and sorting by usage statistics, improving discoverability and user insights, supported by related unit tests.
