 - **Breaking** [1850] (https://github.com/open-telemetry/opentelemetry-rust/pull/1850) `LoggerProvider::log_processors()` and `LoggerProvider::resource()` are not public methods anymore. They are only used within the `opentelemetry-sdk` crate.
 
-- [1857](https://github.com/open-telemetry/opentelemetry-rust/pull/1857) Fixed an issue in the `collect_and_export()` method of the periodic exporter where errors during export were dropped, ensuring proper error handling and reporting. 
+- [1857](https://github.com/open-telemetry/opentelemetry-rust/pull/1857) Fixed an issue in Metrics SDK which prevented export errors from being send to global error handler. With the fix, errors occurring during export like OTLP Endpoint unresponsive shows up in stderr by default.
