+            "Changes to support fully programmable IF frequency.
+             Added support for downstream wireless mode.
+             Updated some mib descriptions for clarity and typos.
+             Added mixed mode to DocsisMacType definition which defines a
+             docsis downstream and euro-docsis upstream configuration that is
+             used by some customers in lieu of annex C mode which the CMTS does
+             not support in hardware.
+             Added support for downstream wireless mode."
