 additional tags and information that is disallowed by the Component Specification. They will be
 removed in a future version once we can rectify those discrepancies, but they are effectively
 removed as of this release: you cannot depend on them still existing.

+#### `component_received_event_bytes_total` and `component_sent_event_bytes_total` consistently use estimated JSON size of the event {#event_json_size}
+
+Prior to this Version, metrics emitted by Vector were inconsistently measuring
+the byte size of the events that were being sent and received. These metrics
+have been updated for all components so they always emit an estimate of the size
+of the event should it be serialized to JSON.
+
+Measuring the events like this allows a consistent measurement to be applied
+across all components regardless of how the source or sink serializes the event
+when connecting to the external service.
