-      <b class="header" style="margin-top: 20px;">0.2.3</b>
-      Axed the unsatisfactory <tt>ino</tt> keyword, replacing it with <tt>of</tt> for
-      object comprehensions. They now look like: <tt>for prop, value of object</tt>.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.2.2</b>
-      When performing a comprehension over an object, use <tt>ino</tt>, instead
-      of <tt>in</tt>, which helps us generate smaller, more efficient code at
-      compile time.
-      <br />
-      Added <tt>::</tt> as a shorthand for saying <tt>.prototype.</tt>
-      <br />
-      The "splat" symbol has been changed from a prefix asterisk <tt>*</tt>, to
-      a postfix ellipsis <tt>...</tt>
-      <br />
-      Added JavaScript's <tt>in</tt> operator,
-      empty <tt>return</tt> statements, and empty <tt>while</tt> loops.
-      <br />
-      Constructor functions that start with capital letters now include a
-      safety check to make sure that the new instance of the object is returned.
-      <br />
-      The <tt>extends</tt> keyword now functions identically to <tt>goog.inherits</tt>
-      in Google's Closure Library.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.2.1</b>
-      Arguments objects are now converted into real arrays when referenced.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.2.0</b>
-      Major release. Significant whitespace. Better statement-to-expression
-      conversion. Splats. Splice literals. Object comprehensions. Blocks.
-      The existence operator. Many thanks to all the folks who posted issues,
-      with special thanks to
-      <a href="http://github.com/kamatsu">Liam O'Connor-Davis</a> for whitespace
-      and expression help.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.1.6</b>
-      Bugfix for running <tt>coffee --interactive</tt> and <tt>--run</tt>
-      from outside of the CoffeeScript directory. Bugfix for nested
-      function/if-statements.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.1.5</b>
-      Array slice literals and array comprehensions can now both take Ruby-style
-      ranges to specify the start and end. JavaScript variable declaration is
-      now pushed up to the top of the scope, making all assignment statements into
-      expressions. You can use <tt>\</tt> to escape newlines.
-      The <tt>coffee-script</tt> command is now called <tt>coffee</tt>.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.1.4</b>
-      The official CoffeeScript extension is now <tt>.coffee</tt> instead of
-      <tt>.cs</tt>, which properly belongs to
-      <a href="http://en.wikipedia.org/wiki/C_Sharp_(programming_language)">C#</a>.
-      Due to popular demand, you can now also use <tt>=</tt> to assign. Unlike
-      JavaScript, <tt>=</tt> can also be used within object literals, interchangeably
-      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.
-      <tt>{"5+5": 10}</tt>.
-      All assignment operators now use a colon: <tt>+:</tt>, <tt>-:</tt>,
-      <tt>*:</tt>, etc.
-    </p>
-
     <p>
