+* 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/functional/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/functional/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]).

+
+[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).

+Note that when writing template classes, you might not want to include the main
+hash header as it's quite an expensive include that brings in a lot of other
+headers, so instead you can include the `<boost/functional/hash_fwd.hpp>`
+header which forward declares [classref boost::hash],
+[funcref boost::hash_range] and [funcref boost::hash_combine]. You'll need to
+include the main header before instantiating [classref boost::hash]. When using
+a container that uses [classref boost::hash] it should do that for you, so your
+type will work fine with the boost hash containers. There's an example of this
+in [@boost:/libs/functional/hash/examples/template.hpp template.hpp] and
