Langfuse release v4.47.0 brings several key observability, ingestion, and infrastructure updates: - Observability & Transcripts : Added the ability to render and measure dedicated trace transcripts, exposed current turn nesting level in transcripts, and labeled experiment query outcomes for SLO tracking. - Worker & Ingestion Performance : Introduced NAPI batch encoding for JS events and added a ClickHouse Native write strategy to workers alongside refactoring of the ClickHouse JSON write strategy. - AI Gateway Updates : Supports setting trace environments using the langfuse-environment header, captures full-mode inputs up to 5 MiB with omitted input markers, and ceases inferring usage for failed or cancelled generations. - Pricing & Ingestion Fixes : Adjusted pricing logic for Anthropic 1-hour cache writes and OpenAI cache-write tokens.
