 - *Breaking* Change return type of `opentelemetry::global::set_tracer_provider` to Unit to align with metrics counterpart
 - Add `get_all` method to `opentelemetry::propagation::Extractor` to return all values of the given propagation key and provide a default implementation.
+- Adds `opentelemetry::AsKeyValues` trait and supporting `opentelemetry::KeyValueCollector` struct to convert types into `KeyValue`s for use as attributes.
 
 ## 0.30.0
