July 2025 monthly summary for grafana/helm-charts: Delivered targeted Tempo Distributed chart improvements to strengthen OTLP gRPC ingestion, improve maintainability, and align documentation. The work focused on refactoring configuration for OpenTelemetry OTLP ingestion, enhancing deployment flexibility, and ensuring documentation reflects current capabilities. Key outcomes include: - Refined Helm chart to enable gRPC OTLP ingestion for Tempo Distributed gateway by removing deprecated gateway.enableGrpc, adopting traces.otlp.grpc.enabled, and adding traces.otlp.grpc.port. This change reduces configuration debt and aligns with OTLP standards. (Commits: d17cec5cdb...) - Fixed critical configuration typos and improved port configurability: corrected oltp -> otlp in gateway config and made the distributor port configurable, enabling flexible deployments across environments. (Commits: 213756d2e4...) - Versioning and documentation alignment: bumped tempo-distributed chart from 1.42.3 to 1.42.4 and updated README/Chart.yaml for consistency, ensuring users have accurate reference and guidance. (Commits: 7bd3e40cf1...; ff4fc591c2... for docs) - Documentation enhancements: added explicit instructions and an example for enabling gRPC OpenTelemetry ingestion via the Tempo distributed chart to accelerate adoption and reduce onboarding time.

May 2025 - grafana/helm-charts: Release hygiene and stability focused. No new features; primary work was a chart version bump to resolve a merge conflict and align release metadata, enabling reproducible downstream deployments.

April 2025: OpenTelemetry gRPC integration for Tempo gateway implemented in grafana/helm-charts. Helm chart updated to enable gRPC endpoints for pushing traces, broadening interoperability with OTEL collectors and systems using gRPC for trace ingestion. This enhances observability pipelines and reduces integration friction for customers using gRPC-based traces.
