-      Added Python-style chained comparisons, the conditional existence
-      operator <tt>?=</tt>, and some examples from <i>Beautiful Code</i>.
-      Bugfixes relating to statement-to-expression conversion, arguments-to-array
-      conversion, and the TextMate syntax highlighter.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.2.5</b>
-      The conditions in switch statements can now take multiple values at once &mdash;
-      If any of them are true, the case will run. Added the long arrow <tt>==></tt>,
-      which defines and immediately binds a function to <tt>this</tt>. While loops can
-      now be used as expressions, in the same way that comprehensions can. Splats
-      can be used within pattern matches to soak up the rest of an array.
-    </p>
-
-    <p>
-      <b class="header" style="margin-top: 20px;">0.2.4</b>
-      Added ECMAScript Harmony style destructuring assignment, for dealing with
-      extracting values from nested arrays and objects. Added indentation-sensitive
-      heredocs for nicely formatted strings or chunks of code.
-    </p>
-
-    <p>
-      <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.
