   8 [section:changes Change Log]
   9
  10 [h2 Boost 1.33.0]
  11
  12 * Initial Release
  13
  14 [h2 Boost 1.33.1]
  15
  16 * Fixed the points example, as pointed out by 沈慧峰.
  17
  18 [h2 Boost 1.34.0]
  19
  20 * Use declarations for standard classes, so that the library
  21   doesn't need to include all of their headers
  22 * Deprecated the `<boost/functional/hash/*.hpp>` headers. Now a single header,
  23   <[headerref boost/functional/hash.hpp]> is used.
  24 * Add support for the `BOOST_HASH_NO_EXTENSIONS` macro, which
  25   disables the extensions to TR1.
  26
  27 * Minor improvements to the hash functions for floating point numbers.
  28 * Update the portable example to hopefully be more generally portable.
  29
  30 [h2 Boost 1.34.1]
  31
  32 * [@http://svn.boost.org/trac/boost/ticket/952 Ticket 952]:
  33   Suppress incorrect 64-bit warning on Visual C++.
  34
  35 [h2 Boost 1.35.0]
  36
  37 * Support for `long long`, `std::complex`.
  38 * Improved algorithm for hashing floating point numbers:
  39   * Improved portablity, as described by Daniel Krügler in
  40     [@http://lists.boost.org/boost-users/2005/08/13418.php
  41     a post to the boost users list].
  42   * Fits more information into each combine loop, which can reduce the
  43     the number of times combine is called and hopefully give a better
  44     quality hash function.
  45   * Improved the algorithm for hashing floating point numbers.
  46   * On Cygwin use a binary hash function for floating point numbers, as
  47     Cygwin doesn't have decent floating point functions for `long double`.
  48   * Never uses `fpclass` which doesn't support `long double`.
  49   * [@http://svn.boost.org/trac/boost/ticket/1064 Ticket 1064]:
  50     Removed unnecessary use of `errno`.
  51 * Explicitly overload for more built in types.
  52 * Minor improvements to the documentation.
  53 * A few bug and warning fixes:
  54   * [@http://svn.boost.org/trac/boost/ticket/1509 Ticket 1509]:
  55     Suppress another Visual C++ warning.
  56   * Some workarounds for the Sun compilers.
  57
  58 [h2 Boost 1.36.0]
  59
  60 * Stop using OpenBSD's dodgy `std::numeric_limits`.
  61 * Using the boost typedefs for `long long` and `unsigned long long`.
  62 * Move the extensions into their own header.
  63
  64 [h2 Boost 1.37.0]
  65
  66 * [@http://svn.boost.org/trac/boost/ticket/2264 Ticket 2264]:
  67   In Visual C++, always use C99 float functions for `long double` and `float` as
  68   the C++ overloads aren't always availables.
  69
  70 [h2 Boost 1.38.0]
  71
  72 * Changed the warnings in the deprecated headers from 1.34.0 to errors. These
  73   will be removed in a future version of Boost.
  74 * Moved detail headers out of `boost/functional/detail`, since they are part of
  75   functional/hash, not functional. `boost/functional/detail/container_fwd.hpp`
  76   has been moved to `boost/detail/container_fwd.hpp` as it's used outside of
  77   this library, the others have been moved to `boost/functional/hash/detail`.
  78
  79 [h2 Boost 1.39.0]
  80
  81 * Move the hash_fwd.hpp implementation into the hash subdirectory, leaving a
  82   forwarding header in the old location. You should still use the old location,
  83   the new location is mainly for implementation and possible modularization.
  84 * [@https://svn.boost.org/trac/boost/ticket/2412 Ticket 2412]: Removed deprecated
  85   headers.
  86 * [@https://svn.boost.org/trac/boost/ticket/2957 Ticket 2957]: Fix configuration
  87   for vxworks.
  88
  89 [h2 Boost 1.40.0]
  90
  91 * Automatically configure the float functions using template metaprogramming
  92   instead of trying to configure every possibility manually.
  93 * Workaround for when STLport doesn't support long double.
  94
  95 [h2 Boost 1.42.0]
  96
  97 * Reduce the number of warnings for Visual C++ warning level 4.
  98 * Some code formatting changes to fit lines into 80 characters.
  99 * Rename an internal namespace.
 100
 101 [h2 Boost 1.43.0]
 102
 103 * [@https://svn.boost.org/trac/boost/ticket/3866 Ticket 3866]:
 104   Don't foward declare containers when using gcc's parallel library,
 105   allow user to stop forward declaration by defining the
 106   `BOOST_DETAIL_NO_CONTAINER_FWD` macro.
 107 * [@https://svn.boost.org/trac/boost/ticket/4038 Ticket 4038]:
 108   Avoid hashing 0.5 and 0 to the same number.
 109 * Stop using deprecated `BOOST_HAS_*` macros.
 110
 111 [h2 Boost 1.44.0]
 112
 113 * Add option to prevent implicit conversions when calling `hash_value` by
 114   defining `BOOST_HASH_NO_IMPLICIT_CASTS`. When using `boost::hash`
 115   for a type that does not have `hash_value` declared but does have
 116   an implicit conversion to a type that does, it would use that
 117   implicit conversion to hash it. Which can sometimes go very wrong,
 118   e.g. using a conversion to bool and only hashing to 2 possible
 119   values. Since fixing this is a breaking change and was only
 120   approached quite late in the release cycle with little discussion
 121   it's opt-in for now. This, or something like it, will become the
 122   default in a future version.
 123
 124 [h2 Boost 1.46.0]
 125
 126 * Avoid warning due with gcc's `-Wconversion` flag.
 127
 128 [h2 Boost 1.50.0]
 129
 130 * [@http://svn.boost.org/trac/boost/ticket/6771 Ticket 6771]:
 131   Avoid gcc's `-Wfloat-equal` warning.
 132 * [@http://svn.boost.org/trac/boost/ticket/6806 Ticket 6806]:
 133   Support `std::array` and `std::tuple` when available.
 134 * Add deprecation warning to the long deprecated
 135   `boost/functional/detail/container_fwd.hpp`.
 136
 137 [h2 Boost 1.51.0]
 138
 139 * Support the standard smart pointers.
 140 * `hash_value` now implemented using SFINAE to avoid implicit casts to built
 141   in types when calling it.
 142 * Updated to use the new config macros.
 143
 144 [h2 Boost 1.52.0]
 145
 146 * Restore `enum` support, which was accidentally removed in the last version.
 147 * New floating point hasher - will hash the binary representation on more
 148   platforms, which should be faster.
 149
 150 [h2 Boost 1.53.0]
 151
 152 * Add support for `boost::int128_type` and `boost::uint128_type` where
 153   available - currently only `__int128` and `unsigned __int128` on some
 154   versions of gcc.
 155 * On platforms that are known to have the standard floating point functions,
 156   don't use automatic detection - which can break if there are ambiguous
 157   overloads.
 158 * Fix undefined behaviour when using the binary float hash (Thomas Heller).
 159
 160 [h2 Boost 1.54.0]
 161
 162 * [@https://svn.boost.org/trac/boost/ticket/7957 Ticket 7957]:
 163   Fixed a typo.
 164
 165 [h2 Boost 1.55.0]
 166
 167 * Simplify a SFINAE check so that it will hopefully work on Sun 5.9
 168   ([ticket 8822]).
 169 * Suppress Visual C++ infinite loop warning ([ticket 8568]).
 170
 171 [h2 Boost 1.56.0]
 172
 173 * Removed some Visual C++ 6 workarounds.
 174 * Ongoing work on improving `hash_combine`. This changes the combine function
 175   which was previously defined in the reference documentation.
 176
 177 [h2 Boost 1.58.0]
 178
 179 * Fixed strict aliasing violation
 180   ([@https://github.com/boostorg/functional/pull/3 GitHub #3]).
 181
 182 [h2 Boost 1.63.0]
 183
 184 * Fixed some warnings.
