+    <ul style="margin-top: 5px;">
+      <li>
+        <tt>Collection#add</tt> now avoids trying to parse a model instance when passing <tt>parse: true</tt>.
+      </li>
+      <li>
+        Bug fix in <tt>Collection#remove</tt>.
+      </li>
+      <li>
+        <tt>Model#save</tt> no longer mutates the passed in attribute hash with the server's
+        response when passing <tt>wait: true</tt>.
+      </li>
+      <li>
+        <tt>Model#fetch</tt> no longer parses the response when passing <tt>patch: false</tt>.
+      </li>
+      <li>
+        Bug fix for iframe-based History when used with jsdom.
+      </li>
+      <li>
+        Bug fix where <tt>Collection#invoke</tt> was not taking additional arguments.
+      </li>
+      <li>
+        When using <tt>on</tt> with an event map, you can now pass the context as the
+        second argument.  This was previously an undocumented behavior from 1.1.2 removed
+        in 1.2.0.
