+      The <a href="/pkg/bytes/#Buffer"><code>Buffer</code></a> type
+      has two new methods:
+      <a href="/pkg/bytes/#Buffer.Available"><code>Available</code></a>
+      and <a href="/pkg/bytes/#AvailableBuffer"><code>AvailableBuffer</code></a>.
+      These may be used along with the
+      <a href="/pkg/bytes/#Buffer.Write"><code>Write</code></a>
+      method to append directly to the <code>Buffer</code>.
