 ### Breaking changes
 
 - Drop Python 3.9 support
   ([#4412](https://github.com/open-telemetry/opentelemetry-python-contrib/pull/4412))
+- `opentelemetry-instrumentation-logging`: Use `LogRecord.getMessage()` to format and extract each log record's body text to more closely match the expected usage of the logging system. As a result, all OTel log record bodies are now always strings.
+  Previously, if `LogRecord.msg` (which contains the format string) was set to a non-string object (e.g. `logger.warning(some_dict)`), the object was exported as-is to the OTLP body field. Now, `LogRecord.getMessage()` will convert it to to a string.
+  If you are passing in non-strings as the format string argument and your backend is expecting them as-is, you will need to update accordingly.
