Unreleased Release Notes

8.2.0-11

Upgrade Notes

• Middleware no longer installs a global OpenTelemetry tracer provider. If oslo.messaging tracing previously relied on that implicit provider and no other component provides a global SDK provider, configure the endpoint and service name under [oslo_messaging_tracing]. RPC spans can continue the API trace through shared OpenTelemetry context.

Bug Fixes

• API spans created by TracingMiddleware now use the configured [oslo_middleware_tracing] service_name, exporter, and sampling rate even when OSProfiler or another component has already installed an OpenTelemetry global tracer provider. Middleware uses its own provider and does not replace or shut down providers owned by other components.
