 New Features:
+   - Added svd_fast(), a routine for computing a singular value decomposition of very 
+     large matrices.
+   - Added cca(), a routine for doing canonical correlation analysis on very large 
+     and high-dimensional datasets.
+   - Added tools for creating parallel for loops, see parallel_for().
    - Added some features to the image display widgets to let the user easily
-     get information about where the user is clicking.  This is the
+     get information about where the user is clicking.  This is the new 
      get_next_double_click() routine.
-   - Added svd_fast()
-   - Added cca()
-   - Added serialization support for std::vector&lt;bool&gt;.
-   - Added make_sparse_vector_inplace()
-   - added the orthogonalize() function.
-   - Added count_bits() and hamming_distance()
-   - Added parallel_for() and parallel_for_blocked()
-   - Added cosine_distance and negative_dot_product_distance
    - Added an operator>> for matrix objects which allows you to read in ASCII
      matrices using the format used by operator&lt;&lt;.
-   - Added average_precision()
+   - Added serialization support for std::vector&lt;bool&gt;.
+   - Added the following new minor objects and routines: average_precision(), 
+     make_sparse_vector_inplace(), orthogonalize(), count_bits(),
+     hamming_distance(), cosine_distance, and negative_dot_product_distance.
 
 Non-Backwards Compatible Changes:
    - Changed ranking evaluation functions to return the mean average precision
      in addition to just raw ranking accuracy. This changes their return types
      from double to matrix&lt;double,1,2&gt;.
    - Generalized segment_image() so it works on any pixel type or array of
-     vectors. I also changed it's interface slightly. In particular, I removed
+     vectors.  I also changed it's interface slightly.  In particular, I removed
      the min_diff parameter and replaced it with an explicit min_size parameter.
 
 Bug fixes:
    - Fixed an endianness bug in the PNG I/O functions which occurred when 16bit
-     grayscale PNGs were used. libpng doesn't automatically convert from host
-     endianness to big endian as the PNG standard demands. You have to explicitly
-     tell it to do this or it will write out the 16bit pixel data in host order
-     which result in the wrong thing happening on little endian chips. Similarly
-     for reading PNGs.
+     grayscale PNGs were used. 
    - Fixed a bug which could potentially occur when empty std::vector&lt;char&gt; or
      std::vector&lt;unsigned char&gt; were serialized.
    - There was a bug in the version of draw_line() that draws directly onto an
