April 2025 delivered across Grafana data sources and core platform with clear business value: improved efficiency, reliability, and observability, underpinned by stronger security and release discipline. Key features and improvements include: Azure Data Explorer data source migrated to the new LLM API with early return when no query is present, reducing unnecessary API calls and aligning with Grafana's LLM capabilities; the 6.0.0 release added a user-visible loading indicator and updated minimum Grafana version with accompanying release notes; Proxy Data Connections (PDC) for Influx SQL enabled secure SOCKS proxy connections, broadening enterprise connectivity; Azure Monitor Basic Logs improvements introduced a single-resource restriction in the UI and optimized plan loading in the Logs Editor/Builder mode to fetch plans only when needed; InfluxDB data source bug fix to validate query type as a string before regex-based variable interpolation, preventing legacy-type errors; Graphite backend now supports multiple time ranges with improved interpolation for more accurate multi-range queries; observability gains include a new gauge to monitor external data source response sizes; and there were comprehensive CI/CD hardening efforts, dependency updates, and maintenance improvements across multiple repos to improve reliability and release hygiene.
