 ----------------
+## 5.0.4 - 2013-10-17
+ - Tweaked delivery receipt helper class to be more compliant w/ SMPP 3.4
+   specs by parsing err code as String rather than as an int. Previous int
+   methods were retained for backwards compatability, but accessing the raw
+   error code as a String is now possible.
