 [section:changes Change Log]
 
 [h2 Boost 1.33.0]
 
 * Initial Release
 
-[h2 Changes in Boost 1.33.1]
+[h2 Boost 1.33.1]
 
 * Fixed the points example, as pointed out by 沈慧峰.
 
-[h2 Changes in Boost 1.34.0]
+[h2 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,
   <[headerref boost/functional/hash.hpp]> is used.
 * Add support for the `BOOST_HASH_NO_EXTENSIONS` macro, which
-  disables the extensions to TR1
+  disables the extensions to TR1.
+
 * Minor improvements to the hash functions for floating point numbers.
+* Update the portable example to hopefully be more generally portable.
 
-[h2 Future Developments]
+[h2 Boost 1.34.1]
 
-* 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`.
+* [@http://svn.boost.org/trac/boost/ticket/952 Ticket 952]:
+  Suppress incorrect 64-bit warning on Visual C++.
+
+[h2 Boost 1.35.0]
+
+* Support for `long long`, `std::complex`.
+* Improved algorithm for hashing floating point numbers:
+  * Improved portablity, as described by Daniel Krügler in
+    [@http://lists.boost.org/boost-users/2005/08/13418.php
+    a post to the boost users list].
+  * Fits more information into each combine loop, which can reduce the
+    the number of times combine is called and hopefully give a better
+    quality hash function.
+  * Improved the algorithm for hashing floating point numbers.
+  * On Cygwin use a binary hash function for floating point numbers, as
+    Cygwin doesn't have decent floating point functions for `long double`.
+  * Never uses `fpclass` which doesn't support `long double`.
+  * [@http://svn.boost.org/trac/boost/ticket/1064 Ticket 1064]:
+    Removed unnecessary use of `errno`.
+* Explicitly overload for more built in types.
+* Minor improvements to the documentation.
+* A few bug and warning fixes:
+  * [@http://svn.boost.org/trac/boost/ticket/1509 Ticket 1509]:
+    Suppress another Visual C++ warning.
+  * Some workarounds for the Sun compilers.
+
+[h2 Boost 1.36.0]
+
+* Stop using OpenBSD's dodgy `std::numeric_limits`.
+* Using the boost typedefs for `long long` and `unsigned long long`.
+* Move the extensions into their own header.
+
+[h2 Boost 1.37.0]
+
+* [@http://svn.boost.org/trac/boost/ticket/2264 Ticket 2264]:
+  In Visual C++, always use C99 float functions for `long double` and `float` as
+  the C++ overloads aren't always availables.
+
+[h2 Boost 1.38.0]
+
+* Changed the warnings in the deprecated headers from 1.34.0 to errors. These
+  will be removed in a future version of Boost.
+* Moved detail headers out of `boost/container_hash/detail`, since they are part of
+  functional/hash, not container_hash. `boost/container_hash/detail/container_fwd.hpp`
+  has been moved to `boost/detail/container_fwd.hpp` as it's used outside of
+  this library, the others have been moved to `boost/functional/hash/detail`.
+
+[h2 Boost 1.39.0]
+
+* Move the hash_fwd.hpp implementation into the hash subdirectory, leaving a
+  forwarding header in the old location. You should still use the old location,
+  the new location is mainly for implementation and possible modularization.
+* [@https://svn.boost.org/trac/boost/ticket/2412 Ticket 2412]: Removed deprecated
+  headers.
+* [@https://svn.boost.org/trac/boost/ticket/2957 Ticket 2957]: Fix configuration
+  for vxworks.
+
+[h2 Boost 1.40.0]
+
+* Automatically configure the float functions using template metaprogramming
+  instead of trying to configure every possibility manually.
+* Workaround for when STLport doesn't support long double.
+
+[h2 Boost 1.42.0]
+
+* Reduce the number of warnings for Visual C++ warning level 4.
+* Some code formatting changes to fit lines into 80 characters.
+* Rename an internal namespace.
+
+[h2 Boost 1.43.0]
+
+* [@https://svn.boost.org/trac/boost/ticket/3866 Ticket 3866]:
+  Don't foward declare containers when using gcc's parallel library,
+  allow user to stop forward declaration by defining the
+  `BOOST_DETAIL_NO_CONTAINER_FWD` macro.
+* [@https://svn.boost.org/trac/boost/ticket/4038 Ticket 4038]:
+  Avoid hashing 0.5 and 0 to the same number.
+* Stop using deprecated `BOOST_HAS_*` macros.
+
+[h2 Boost 1.44.0]
+
+* Add option to prevent implicit conversions when calling `hash_value` by
+  defining `BOOST_HASH_NO_IMPLICIT_CASTS`. When using `boost::hash`
+  for a type that does not have `hash_value` declared but does have
+  an implicit conversion to a type that does, it would use that
+  implicit conversion to hash it. Which can sometimes go very wrong,
+  e.g. using a conversion to bool and only hashing to 2 possible
+  values. Since fixing this is a breaking change and was only
+  approached quite late in the release cycle with little discussion
+  it's opt-in for now. This, or something like it, will become the
+  default in a future version.
+
+[h2 Boost 1.46.0]
+
+* Avoid warning due with gcc's `-Wconversion` flag.
+
+[h2 Boost 1.50.0]
+
+* [@http://svn.boost.org/trac/boost/ticket/6771 Ticket 6771]:
+  Avoid gcc's `-Wfloat-equal` warning.
+* [@http://svn.boost.org/trac/boost/ticket/6806 Ticket 6806]:
+  Support `std::array` and `std::tuple` when available.
+* Add deprecation warning to the long deprecated
+  `boost/container_hash/detail/container_fwd.hpp`.
+
+[h2 Boost 1.51.0]
+
+* Support the standard smart pointers.
+* `hash_value` now implemented using SFINAE to avoid implicit casts to built
+  in types when calling it.
+* Updated to use the new config macros.
+
+[h2 Boost 1.52.0]
+
+* Restore `enum` support, which was accidentally removed in the last version.
+* New floating point hasher - will hash the binary representation on more
+  platforms, which should be faster.
+
+[h2 Boost 1.53.0]
+
+* Add support for `boost::int128_type` and `boost::uint128_type` where
+  available - currently only `__int128` and `unsigned __int128` on some
+  versions of gcc.
+* On platforms that are known to have the standard floating point functions,
+  don't use automatic detection - which can break if there are ambiguous
+  overloads.
+* Fix undefined behaviour when using the binary float hash (Thomas Heller).
+
+[h2 Boost 1.54.0]
+
+* [@https://svn.boost.org/trac/boost/ticket/7957 Ticket 7957]:
+  Fixed a typo.
+
+[h2 Boost 1.55.0]
+
+* Simplify a SFINAE check so that it will hopefully work on Sun 5.9
+  ([ticket 8822]).
+* Suppress Visual C++ infinite loop warning ([ticket 8568]).
+
+[h2 Boost 1.56.0]
+
+* Removed some Visual C++ 6 workarounds.
+* Ongoing work on improving `hash_combine`. This changes the combine function
+  which was previously defined in the reference documentation.
+
+[h2 Boost 1.58.0]
+
+* Fixed strict aliasing violation
+  ([@https://github.com/boostorg/container_hash/pull/3 GitHub #3]).
+
+[h2 Boost 1.63.0]
+
+* Fixed some warnings.
+* Only define hash for `std::wstring` when we know we have a `wchar_t`.
+  Otherwise there's a compile error as there's no overload for hashing
+  the characters in wide strings ([ticket 8552]).
+
+[h2 Boost 1.64.0]
+
+* Fix for recent versions of Visual C++ which have removed `std::unary_function`
+  and `std::binary_function` ([ticket 12353]).
+
+[h2 Boost 1.65.0]
+
+* Support for `char16_t`, `char32_t`, `u16string`, `u32string`
+
+[h2 Boost 1.66.0]
+
+* Avoid float comparison warning when using Clang - this workaround was
+  already in place for GCC, and was used when Clang pretends to be GCC,
+  but the warning was appearing when running Clang in other contexts.
+
+[h2 Boost 1.67.0]
+
+* Moved library into its own module, `container_hash`.
+* Moved headers for new module name, now at:
+  `<boost/container_hash/hash.hpp>`,
+  `<boost/container_hash/hash_fwd.hpp>`,
+  `<boost/container_hash/extensions.hpp>`.
+* Added forwarding headers to support the old headers locations.
+* Support `std::string_view`, `std::error_code`, `std::error_condition`
+  `std::optional`, `std::variant`, `std::monostate` where available.
+* Update include paths from other Boost libraries.
+* Manually write out tuple overloads, rather than using the
+  preprocessor to generate them. Should improve usability, due
+  to better error messages, and easier debugging.
+* Fix tutorial example ([ticket 11017]).
+* Quick fix for hashing `vector<bool>` when using libc++. Will try to introduce
+  a more general fix in the next release.

+
+[section:rationale Rationale]
+
+The rationale can be found in the original design
+[footnote issue 6.18 of the __issues__ (page 63)].
+
+[heading Quality of the hash function]
+
+Many hash functions strive to have little correlation between the input
+and output values. They attempt to uniformally distribute the output
+values for very similar inputs. This hash function makes no such
+attempt. In fact, for integers, the result of the hash function is often
+just the input value. So similar but different input values will often
+result in similar but different output values.
+This means that it is not appropriate as a general hash function. For
+example, a hash table may discard bits from the hash function resulting
+in likely collisions, or might have poor collision resolution when hash
+values are clustered together. In such cases this hash function will
+preform poorly.
+
+But the standard has no such requirement for the hash function,
+it just requires that the hashes of two different values are unlikely
+to collide. Containers or algorithms
+designed to work with the standard hash function will have to be
+implemented to work well when the hash function's output is correlated
+to its input. Since they are paying that cost a higher quality hash function
+would be wasteful.
+
+For other use cases, if you do need a higher quality hash function,
+then neither the standard hash function or `boost::hash` are appropriate.
+There are several options
+available. One is to use a second hash on the output of this hash
+function, such as [@http://web.archive.org/web/20121102023700/http://www.concentric.net/~Ttwang/tech/inthash.htm
+Thomas Wang's hash function]. This this may not work as
+well as a hash algorithm tailored for the input.
+
+For strings there are several fast, high quality hash functions
+available (for example [@http://code.google.com/p/smhasher/ MurmurHash3]
+and [@http://code.google.com/p/cityhash/ Google's CityHash]),
+although they tend to be more machine specific.
+These may also be appropriate for hashing a binary representation of
+your data - providing that all equal values have an equal
+representation, which is not always the case (e.g. for floating point
+values).

 When writing a hash function, first look at how the equality function works.
 Objects that are equal must generate the same hash value.
 When objects are not equal they should generate different hash values.
 In this object equality was based just on the id so the hash function
