March 2025—Delivered critical documentation-driven enablement for Dash0 OpenTelemetry integration in two repos. Added Dash0 OTEL documentation to kumahq/kuma-website and Mastra, including configuration steps, an OTLP export example for Mastra (TypeScript), and a provider-list update to include Dash0. These efforts lower onboarding friction for Dash0 users and expand observability options, reinforcing a more competitive telemetry story across Kuma and Mastra. No major bugs fixed this month; focus remained on documentation, tutorials, and cross-repo alignment.
