Langfuse 4.72.0 adds an analytics tab in AI Gateway settings and attributes gateway spans to their API key and service. It also updates onboarding and user attribution for generated keys.
Route events into operations
PagerDuty integration can send alerts, project notifications and prompt changes, with the routing key configured on the automation. This is a notification integration, not evidence that an alert reaches an on-call responder in every deployment.
Evaluation filters gain trace-level conditions. This lets teams target evaluation rules using trace context rather than treating every trace as equivalent.
Self-hosted behavior to review
The release adds reporting of AI Gateway request counts from self-hosted instances. Operators should review that telemetry change alongside their deployment settings. It also corrects double counting of cache-write TTL usage in generic OpenTelemetry mapping. Accounting corrections should not be mistaken for a change in underlying model-provider prices.
