+* A new feature referred to as "tombstoned voting" was added to the Raft
+  consensus subsystem to allow tablet replicas in the `TABLET_DATA_TOMBSTONED`
+  state to vote in tablet leader elections. This feature increases Kudu's
+  stability and availability by improving the likelihood that Kudu will be able
+  to self-heal in more edge-case scenarios, such as when tablet copy operations
+  fail. See link:https://issues.apache.org/jira/browse/KUDU-871[KUDU-871] for
+  details.
