 * Fix: remote output parser now correctly matches refs with non-ASCII
   chars in them
+* API: Diffs now have `a_rawpath`, `b_rawpath`, `raw_rename_from`,
+  `raw_rename_to` properties, which are the raw-bytes equivalents of their
+  unicode path counterparts.
 * Fix: TypeError about passing keyword argument to string decode() on
   Python 2.6.
 * Feature: `setUrl API on Remotes <https://github.com/gitpython-developers/GitPython/pull/446#issuecomment-224670539>`_
