• Meta tags and how to leverage them in large scale environments.
• Diagnosing query issues using series Lineage and its Grafana integration.
• Optimizing query performance through request performance metadata, aggregators and normalization.
• Governance, website and more updates.

Also: new features available in Graphite and Carbon-relay-NG.
