-      Due to popular demand, you can now also use <tt>=</tt> to assign. Unlike

-      with <tt>:</tt>. Made a grammatical fix for chained function calls
-      like <tt>func(1)(2)(3)(4)</tt>. Inheritance and super no longer use
-      <tt>__proto__</tt>, so they should be IE-compatible now.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.1.3</b>
-      The <tt>coffee</tt> command now includes <tt>--interactive</tt>,
-      which launches an interactive CoffeeScript session, and <tt>--run</tt>,
-      which directly compiles and executes a script. Both options depend on a
-      working installation of Narwhal.
-      The <tt>aint</tt> keyword has been replaced by <tt>isnt</tt>, which goes
-      together a little smoother with <tt>is</tt>.
-      Quoted strings are now allowed as identifiers within object literals: eg.
