+      <ul>
+        <li>
+          Bugfix for interpolation in the first key of an object literal in an
+          implicit call.
+        </li>
+        <li>
+          Fixed broken error messages in the REPL, as well as a few minor bugs
+          with the REPL.
+        </li>
+        <li>
+          Fixed source mappings for tokens at the beginning of lines when
+          compiling with the <tt>--bare</tt> option. This has the nice side
+          effect of generating smaller source maps.
+        </li>
+        <li>
+          Slight formatting improvement of compiled block comments.
+        </li>
+        <li>
+          Better error messages for <tt>on</tt>, <tt>off</tt>, <tt>yes</tt> and
+          <tt>no</tt>.
+        </li>

+

+      <%= releaseHeader('2015-04-15', '1.9.2', '1.9.1') %>
+      <ul>
+        <li>
+          Fixed a <b>watch</b> mode error introduced in 1.9.1 when compiling
+          multiple files with the same filename.
+        </li>
+        <li>
+          Bugfix for <tt>yield</tt> around expressions containing
+          <tt>this</tt>.
+        </li>
+        <li>
+          Added a Ruby-style <tt>-r</tt> option to the REPL, which allows
+          requiring a module before execution with <tt>--eval</tt> or
+          <tt>--interactive</tt>.
+        </li>
+        <li>
+          In <tt>&lt;script type="text/coffeescript"&gt;</tt> tags, to avoid
+          possible duplicate browser requests for .coffee files, 
+          you can now use the <tt>data-src</tt> attribute instead of <tt>src</tt>.
+        </li>
+        <li>
+          Minor bug fixes for IE8, strict ES5 regular expressions and Browserify.
+        </li>
+      </ul>
+    </p>
+
+    <p>
+      <%= releaseHeader('2015-02-18', '1.9.1', '1.9.0') %>
+      <ul>
+        <li>
+          Interpolation now works in object literal keys (again). You can use this to
+          dynamically name properties.
+        </li>
+        <li>
+          Internal compiler variable names no longer start with underscores. This makes
+          the generated JavaScript a bit prettier, and also fixes an issue with
+          the completely broken and ungodly way that AngularJS "parses" function
+          arguments.
+        </li>
+        <li>
+          Fixed a few <tt>yield</tt>-related edge cases with <tt>yield return</tt>
+          and <tt>yield throw</tt>.
+        </li>
+        <li>
+          Minor bug fixes and various improvements to compiler error messages.

+      <%= releaseHeader('2015-01-29', '1.9.0', '1.8.0') %>
+      <ul>
+        <li>
+          CoffeeScript now supports ES6 generators. A generator is simply a function
+          that <tt>yield</tt>s.
+        </li>
+        <li>
+          More robust parsing and improved error messages for strings and regexes —
+          especially with respect to interpolation.
+        </li>
+        <li>
+          Changed strategy for the generation of internal compiler variable names.
+          Note that this means that <tt>@example</tt> function parameters are no longer
+          available as naked <tt>example</tt> variables within the function body.
+        </li>
+        <li>
+          Fixed REPL compatibility with latest versions of Node and Io.js.
