+v1.15.3
+===
+
+This patch release fixes one minor bug, reduces allocations on gzip and lz4
+decompression, and contains a behavior improvement when OffsetOutOfRange is
+received while consuming.
+
+For the bugfix: previously, if the client was using a fetch session (as is the
+default when consuming), and all partitions for a topic transfer to a different
+broker, the client would not properly unregister the topic from the prior
+broker's fetch session. This could result in more data being consumed and
+discarded than necessary (although, it's possible the broker just reset the
+fetch session anyway, I'm not entirely positive).
