 =====
 
+Features
+--------
+    - Row keys are now bytes: keys stored by versions prior to 0.7.0 will be
+      returned as UTF-8 encoded bytes. OrderPreservingPartitioner and
+      CollatingOrderPreservingPartitioner continue to expect that keys contain
+      UTF-8 encoded strings, but RandomPartitioner no longer expects strings.
+    - A new ByteOrderedPartitioner supports bytes keys with arbitrary content,
+      and orders keys by their byte value.
