 -------------------------------------------
 This release contains the following highlights:
 
+  * Performance Improvements:
+
+    * **Master `/state` endpoint:** Adopted RapidJSON and reduced
+      copying for a ~130% throughput improvement due to a ~55%
+      decrease in latency (MESOS-9092). Also, added parallel
+      processing of `/state` requests to reduce master backlogging
+      / interference under high request load (MESOS-9122).
+
+    * **Allocator:** Improved allocator cycle time significantly
+      (MESOS-9087). This, together with the reduced master
+      backlogging from `/state` improvements, reduces the
+      end-to-end offer cycling time between Mesos and schedulers.
+
+    * **Agent `/containers` endpoint:** Fixed a performance issue
+      that caused high latency / cpu consumption when there are
+      many containers on the agent (MESOS-8418).
+
+    * **Agent container launching performance improvements**:
+      The expensive `cgroups::verify()` calls were removed which
+      provides a significant improvement to container launch /
+      destroy throughput (MESOS-9081).
+
   * [MESOS-7691] - Added a new option `cgroups/all` to the agent flag
     `--isolation`. This allows cgroups isolator to automatically load
     all the local enabled cgroups subsystems. If this option is specified
