 - Bump MSRV to 1.70 [#2179](https://github.com/open-telemetry/opentelemetry-rust/pull/2179)
 - Implement `LogRecord::set_trace_context` for `LogRecord`. Respect any trace context set on a `LogRecord` when emitting through a `Logger`.
 - Improved `LoggerProvider` shutdown handling to prevent redundant shutdown calls when `drop` is invoked. [#2195](https://github.com/open-telemetry/opentelemetry-rust/pull/2195)
