-      TODO: <a href="https://golang.org/cl/345569">https://golang.org/cl/345569</a>: add Writer.AvailableBuffer
+      The new <a href="/pkg/bufio#AvailableBuffer"><code>Writer.AvailableBuffer</code></a>
+      method returns an empty buffer with a possibly non-empty capacity for use
+      with append-like APIs. After appending, the buffer can be provided to a
+			succeeding <code>Write</code> call and possibly avoid any copying.

+      <a href="/pkg/bufio#Writer.Reset"><code>Writer.Reset</code></a>
+      now use the default buffer size when called on objects with a
