+HDFS RBF: RDBMS based token storage support
+----------------------------------------
+HDFS Router-Router Based Federation now supports storing delegation tokens on MySQL,
+[HADOOP-18535](https://issues.apache.org/jira/browse/HADOOP-18535)
+which improves token operation throughput over the original Zookeeper-based implementation.
+
+
+New File System APIs
+----------------------------------------
+[HADOOP-18671](https://issues.apache.org/jira/browse/HADOOP-18671) moved a number of
+HDFS-specific APIs to Hadoop Common to make it possible for certain applications that
+depend on HDFS semantics to run on other Hadoop compatible file systems.
+
+In particular, recoverLease() and isFileClosed() are exposed through LeaseRecoverable
+interface. While setSafeMode() is exposed through SafeMode interface.
