+Notes:
+
+While opentelemetry-cpp Logs are still in experimental stage,
+[#1383](https:/open-telemetry/opentelemetry-cpp/pull/1383) updated
+opentelemetry-proto to 0.17.0, which includes some breaking change in the
+protocol, like
+[this](https:/open-telemetry/opentelemetry-proto/pull/373). This
+makes `name` parameter for our log API unnecessary. However, this parameter is
+marked deprecated instead of being removed in this release, and it will be
+removed in future release.
