Langfuse 4.34.0 starts building a Rust AI gateway and marks the legacy ingestion endpoints as about 10 minutes delayed
GitHub·low signal
langfuse/langfuse v4.34.0 (2026-09-11) bootstraps a Rust AI gateway service and adds an organization control plane for it (#17188, #17085). That puts Langfuse into LLM gateways, where LiteLLM already sits. Legacy API endpoints now say they delay data by about 10 minutes, and successful legacy ingestion writes carry a `_deprecation` field. The release also adds user-triggered session revocation and attaches OTEL trace IDs to tRPC errors.
