 ## Unreleased
 
+* Add the `StreamConsumer::split_partition_queue` method to mirror
+  `BaseConsumer::split_partition_queue` ([#411]).
+
+  Thanks to [@davidblewett], [@duarten], and [@nemosupremo] for contributing to
+  the implementation.
+
+* **Breaking change.** Remove the `StreamConsumerContext` type and the
+  `ConsumerContext::message_queue_nonempty_callback` method. These were
+  essentially implementation details of `StreamConsumer` that had leaked into
+  the public API. The vast majority of users should be unaffected.
+
+* **Breaking change.** Remove the type parameters from the `MessageStream` type.
+
+* **Breaking change.** Add the received `TopicPartitionList` to the
+  `Rebalance::Revoke` variant, which is useful when using incremental
+  cooperative rebalancing ([#398]).
+
+* Avoid crashing if librdkafka invokes the commit callback with a null
+  topic partition list ([#406]).
+
+  Thanks, [@thijsc].
+
 * Add the new statistics fields in librdkafka v1.7.0 to the various statistics
   types. The new fields are:

   statistics from librdkafka. The default implementation calls
   `ClientContext::stats` with the decoded statistics.

+* Add the `Default` trait to the statistics types: `Statistics`, `Broker`,

-* **Breaking change.** The `MessageStream` type is no longer generic.
+* Add the `Debug` trait to `DefaultClientContext` and `DefaultConsumerContext`
+  ([#401]).
 
-* Add the `StreamConsumer::split_partition_queue` method to mirror
-  `BaseConsumer::split_partition_queue`.
