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. | |
