+Changes to the Hexagon Target
+-----------------------------
+
+* Hexagon now supports auto-vectorization for HVX. It is disabled by default
+  and can be turned on with ``-fvectorize``. For auto-vectorization to take
+  effect, code genration for HVX needs to be enabled with ``-mhvx``.
+  The complete set of options should include ``-fvectorize``, ``-mhvx``,
+  and ``-mhvx-length={64b|128b}``.
+
+* The support for Hexagon ISA V4 is deprecated and will be removed in the
+  next release.
