 New Features:
-  - Added the ability to label parts of objects with the mouse to the image_display widget.
-  - Added the start_async() function to the server object.
-  - Added the ability to put overlay circles and full_object_detections into the image_window widget.
-  - Added a stddev() for matrix objects.
-  - Added operator+() for running_stats and running_scalar_covariance
-  - Added BSP tools
-  - Added connection::disable_nagle()
+   - Machine Learning
+      - Added the ability to learn non-negative weight vectors to the 
+        structural_assignment_trainer object.
+      - Added two new graph clustering algorithms: Chinese Whispers and
+        Newman's modularity clustering.
+      - Added a number of new graph manipulation tools:
+        sparse_matrix_vector_multiply(), is_ordered_by_index(),
+        find_neighbor_ranges(), convert_unordered_to_ordered(),
+        remove_duplicate_edges(), and the ordered_sample_pair object.
+   - Networking
+      - Added a set of tools for creating applications using the Bulk Synchronous
+        Parallel computing model.  See the new bsp_ex.cpp example program for an
+        introduction.
+      - Added a routine that lets a user disable Nagle's algorithm on a TCP 
+        connection.
+      - Added an asynchronous start routine to the server object.  This is the new
+        start_async() method.
       - Added the network_address object.
-  - Added connect_to() to the bridge interface 
-  - Added the ability to learn non-negative weight vectors to the structural_assignment_trainer object.
-  - Added an overload of murmur_hash3_128bit() that takes 4 integers instead of a block of memory.
-  - Added remove_duplicate_edges().
-  - Added ordered_sample_pair 
+      - Added connect_to() to the bridge interface.
+   - Added find_max_parse_cky(), a method implementing the well known CKY algorithm
+     for parsing probabilistic context free grammars.
+   - Added the ability to label parts of objects with the mouse to the image_display
+     widget.
+   - Added the ability to put overlay circles and full_object_detections into the
+     image_window widget.
+   - Added a stddev() for matrix objects.
+   - Added operator+() for running_stats and running_scalar_covariance.
+   - Added an overload of murmur_hash3_128bit() that takes 4 integers instead of a
+     block of memory.
    - Added rand::get_random_64bit_number().
-  - Added sparse_matrix_vector_multiply()
-  - Added is_ordered_by_index(), find_neighbor_ranges(), and convert_unordered_to_ordered()
-  - Added newman_cluster(), chinese_whispers(), and modularity() routines.
-  - Added find_max_parse_cky()
 
 Non-Backwards Compatible Changes:
    - Changed the image_dataset_metadata XML reading tools to use a map of strings to
-    points to represent object parts. This change also removes the old head point 
-    from a box since this information can now be represented in the parts map.
-  - Broke backwards compatibility, the syntax for passing order_by_distance and
-    order_by_index to std::sort() is now slightly different since these functions are
-    now templates. This allows them to work on any kind of sample_pair or
-    ordered_sample_pair object.
-  - The default distance of a sample_pair that was default initialized is 1 now
-    instead of infinity.

 Bug fixes:
    - Added a patch, contributed by Martin Müllenhaupt, to fix a minor bug in the
      SQLite bindings.
-  - Fixed a typo which would prevent code that called running_stats::max_n() from compiling.

 Other:
    - Added a new documentation page for the various graph tools in dlib.
-  - Added support for Visual Studio 2012
-  - Switched the sample_pair object to use double to store its distance value instead of float.
-  - Added William Sobel's patch to the web server that improves its flexibility and security.

    - Changed the server object so you don't have to use the server::kernel_1a syntax
-    anymore to declare it.  Now you just say server, server_iostream, or server_http
-    depending on which one you want.
-  - Set the default max number of connections a server will accept at a time to 1000
-    rather than the previous default of infinity.
