 ### Breaking changes
 
+- Some debug metrics for `otelcol` components have changed. (@thampiotr)
+  For example, `otelcol.exporter.otlp`'s `exporter_sent_spans_ratio_total` metric is now `otelcol_exporter_sent_spans_total`.
+
 - [otelcol.processor.transform] The functions `convert_sum_to_gauge` and `convert_gauge_to_sum` must now be used in the `metric` `context` rather than in the `datapoint` context.
