 ## Unreleased
 
+- Overwrite logging.config.fileConfig and logging.config.dictConfig to ensure
+the OTLP `LogHandler` remains attached to the root logger. Fix a bug that
+can cause a deadlock to occur over `logging._lock` in some cases ([#4636](https://github.com/open-telemetry/opentelemetry-python/pull/4636)).
 - Update OTLP proto to v1.7 [#4645](https://github.com/open-telemetry/opentelemetry-python/pull/4645).
 - Add `event_name` as a top level field in the `LogRecord`. Events are now simply logs with the
 `event_name` field set, the logs SDK should be used to emit events ([#4652](https://github.com/open-telemetry/opentelemetry-python/pull/4652)).
