First release of opentelemetry-propagator-b3 , providing B3 trace context propagation for OpenTelemetry Rust.
First release of opentelemetry-propagator-b3, providing B3 trace context propagation for OpenTelemetry Rust.
Based on the B3 implementation in opentelemetry-zipkin, with the existing API and behavior. B3 users can migrate their dependency and imports to opentelemetry_propagator_b3::{B3Encoding, Propagator}.
See the 0.33.0 release notes and migration guidance.
The OTLP exporters for Logs and Metrics remain release candidates. We plan to declare them stable in 0.33.1 after approximately two weeks of validation, provided no issues requiring breaking API changes arise. The Logs and Metrics API and SDK remain stable; Distributed Tracing remains pre-stable.
