@@ -14,6 +14,8 @@ now use `.with_resource(RESOURCE::default())` to configure Resource when using
 `OtlpLogPipeline`.
 - **Breaking** The methods `OtlpTracePipeline::install_simple()` and `OtlpTracePipeline::install_batch()` would now return `TracerProvider` instead of `Tracer`.
   These methods would also no longer set the global tracer provider. It would now be the responsibility of users to set it by calling `global::set_tracer_provider(tracer_provider.clone());`. Refer to the [basic-otlp](https://github.com/open-telemetry/opentelemetry-rust/blob/main/opentelemetry-otlp/examples/basic-otlp/src/main.rs) and [basic-otlp-http](https://github.com/open-telemetry/opentelemetry-rust/blob/main/opentelemetry-otlp/examples/basic-otlp-http/src/main.rs) examples on how to initialize OTLP Trace Exporter.
