+        1.1.3 — Dec 1, 2010

+        In CommonJS, Underscore may now be required with just: 

+        var _ = require("underscore").
+        Added _.throttle and _.debounce functions.
+        Removed _.breakLoop, in favor of an ECMA5-style un-break-able
+        each implementation — this removes the try/catch, and you'll now have
+        better stack traces for exceptions that are thrown within an Underscore iterator.
+        Improved the isType family of functions for better interoperability
+        with Internet Explorer host objects.
+        _.template now correctly escapes backslashes in templates.
+        Improved _.reduce compatibility with the ECMA5 version: 
+        if you don't pass an initial value, the first item in the collection is used.
+      

+
