 Changes
 =======
+2.3 (2013-12-08)
+----------------
+* Add `hash128`, which returns a 128-bit signed integer.
+* Fix a misplaced operator which could cause memory leak in a rare condition.
+* Fix a malformed value to a Python/C API function which may cause runtime errors in recent Python 3.x versions.
+
+The first two commits are from `Derek Wilson <https://github.com/underrun>`_. Thanks!
