+    aiokafka: Fixes ``kafka.partition`` and ``kafka.message_offset`` span tags
+    being incorrectly set to ``-1``. Consumer spans no longer misreport ``0``
+    (e.g. single-partition topics or the first message in a partition) due to
+    falsy evaluation. Producer spans and any span where the value is genuinely
+    unknown now omit these tags entirely rather than emitting a misleading ``-1``.
