+[h2 Boost 1.33.0]
+
+* Initial Release
+
+[h2 Changes in Boost 1.33.1]
+
+* Fixed the points example, as pointed out by 沈慧峰.
+
+[h2 Changes in Boost 1.34.0]
+
+* Use declarations for standard classes, so that the library
+  doesn't need to include all of their headers
+* Deprecated the `<boost/functional/hash/*.hpp>` headers. Now a single header,
+  `<boost/functional/hash.hpp>` is used.
+* Add support for the BOOST_HASH_NO_EXTENSIONS macro, which
+  disables the extensions to TR1
+* Minor improvements to the hash functions for floating point numbers.
+
+[h2 Future Developments]
+
+* A more portable hash function, as described by Daniel Krügler in
+ [@http://lists.boost.org/boost-users/2005/08/13418.php a post to the boost users list].
+* Implement `hash_value` for more classes, including `std::complex`.

 The implementation of the hash function for pointers is based on suggestions
 made by Alberto Barbati and Dave Harris. Dave Harris also suggested an
 important improvement to [funcref boost::hash_combine] that was taken up.

 The original implementation came from Jeremy B. Maitin-Shepard's hash table
 library, although this is a complete rewrite.
