   are available.
 * Added equality operators.
 
+[h2 Boost 1.37.0]
+
+* Rename overload of `emplace` with hint, to `emplace_hint` as specified in
+  [@http://www.open-std.org/JTC1/SC22/WG21/docs/papers/2008/n2691.pdf n2691].
+* Provide forwarding headers at `<boost/unordered/unordered_map_fwd.hpp>` and
+  `<boost/unordered/unordered_set_fwd.hpp>`.
+* Move all the implementation inside `boost/unordered`, to assist
+  modularization and hopefully make it easier to track changes in subversion.
+
+[h2 Boost 1.38.0]
+
+* Use [@boost:/libs/core/swap.html `boost::swap`].
+* [@https://svn.boost.org/trac/boost/ticket/2237 Ticket 2237]:
+  Document that the equality and inequality operators are undefined for two
+  objects if their equality predicates aren't equivalent. Thanks to Daniel
+  Krügler.
+* [@https://svn.boost.org/trac/boost/ticket/1710 Ticket 1710]: 
+  Use a larger prime number list. Thanks to Thorsten Ottosen and Hervé
+  Brönnimann.
+* Use
+  [@boost:/libs/type_traits/doc/html/boost_typetraits/category/alignment.html
+  aligned storage] to store the types. This changes the way the allocator is
+  used to construct nodes. It used to construct the node with two calls to
+  the allocator's `construct` method - once for the pointers and once for the
+  value. It now constructs the node with a single call to construct and
+  then constructs the value using in place construction.
+* Add support for C++0x initializer lists where they're available (currently
+  only g++ 4.4 in C++0x mode).
+
+[h2 Boost 1.39.0]
+
+* [@https://svn.boost.org/trac/boost/ticket/2756 Ticket 2756]: Avoid a warning
+  on Visual C++ 2009.
+* Some other minor internal changes to the implementation, tests and
+  documentation.
+* Avoid an unnecessary copy in `operator[]`.
+* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]: Fix length of
+  prime number list.
+
+[h2 Boost 1.40.0]
+
+* [@https://svn.boost.org/trac/boost/ticket/2975 Ticket 2975]:
+  Store the prime list as a preprocessor sequence - so that it will always get
+  the length right if it changes again in the future.
+* [@https://svn.boost.org/trac/boost/ticket/1978 Ticket 1978]:
+  Implement `emplace` for all compilers.
+* [@https://svn.boost.org/trac/boost/ticket/2908 Ticket 2908],
+  [@https://svn.boost.org/trac/boost/ticket/3096 Ticket 3096]:
+  Some workarounds for old versions of borland, including adding explicit
+  destructors to all containers.
+* [@https://svn.boost.org/trac/boost/ticket/3082 Ticket 3082]:
+  Disable incorrect Visual C++ warnings.
+* Better configuration for C++0x features when the headers aren't available.
+* Create less buckets by default.
+
+[h2 Boost 1.41.0 - Major update]
+
+* The original version made heavy use of macros to sidestep some of the older
+  compilers' poor template support. But since I no longer support those
+  compilers and the macro use was starting to become a maintenance burden it
+  has been rewritten to use templates instead of macros for the implementation
+  classes.
+
+* The container objcet is now smaller thanks to using `boost::compressed_pair`
+  for EBO and a slightly different function buffer - now using a bool instead
+  of a member pointer.
+
+* Buckets are allocated lazily which means that constructing an empty container
+  will not allocate any memory.
+  
+[h2 Boost 1.42.0]
+
+* Support instantiating the containers with incomplete value types.
+* Reduced the number of warnings (mostly in tests).
+* Improved codegear compatibility.
+* [@http://svn.boost.org/trac/boost/ticket/3693 Ticket 3693]:
+  Add `erase_return_void` as a temporary workaround for the current
+  `erase` which can be inefficient because it has to find the next
+  element to return an iterator.
+* Add templated find overload for compatible keys.
+* [@http://svn.boost.org/trac/boost/ticket/3773 Ticket 3773]:
+  Add missing `std` qualifier to `ptrdiff_t`.
+* Some code formatting changes to fit almost all lines into 80 characters.
+
+[h2 Boost 1.43.0]
+
+* [@http://svn.boost.org/trac/boost/ticket/3966 Ticket 3966]:
+  `erase_return_void` is now `quick_erase`, which is the
+  [@http://home.roadrunner.com/~hinnant/issue_review/lwg-active.html#579
+  current forerunner for resolving the slow erase by iterator], although
+  there's a strong possibility that this may change in the future. The old
+  method name remains for backwards compatibility but is considered deprecated
+  and will be removed in a future release.
+* Use Boost.Exception.
+* Stop using deprecated `BOOST_HAS_*` macros.
+
+[h2 Boost 1.45.0]
+
+* Fix a bug when inserting into an `unordered_map` or `unordered_set` using
+  iterators which returns `value_type` by copy.
+
+[h2 Boost 1.48.0 - Major update]
+
+This is major change which has been converted to use Boost.Move's move
+emulation, and be more compliant with the C++11 standard. See the
+[link unordered.compliance compliance section] for details.
+
+The container now meets C++11's complexity requirements, but to do so
+uses a little more memory. This means that `quick_erase` and
+`erase_return_void` are no longer required, they'll be removed in a
+future version.
+
+C++11 support has resulted in some breaking changes:
+
+* Equality comparison has been changed to the C++11 specification.
+  In a container with equivalent keys, elements in a group with equal
+  keys used to have to be in the same order to be considered equal,
+  now they can be a permutation of each other. To use the old
+  behavior define the macro `BOOST_UNORDERED_DEPRECATED_EQUALITY`.
+
+* The behaviour of swap is different when the two containers to be
+  swapped has unequal allocators. It used to allocate new nodes using
+  the appropriate allocators, it now swaps the allocators if
+  the allocator has a member structure `propagate_on_container_swap`,
+  such that `propagate_on_container_swap::value` is true.
+
+* Allocator's `construct` and `destroy` functions are called with raw
+  pointers, rather than the allocator's `pointer` type.
+
+* `emplace` used to emulate the variadic pair constructors that
+  appeared in early C++0x drafts. Since they were removed it no
+  longer does so. It does emulate the new `piecewise_construct`
+  pair constructors - only you need to use
+  `boost::piecewise_construct`. To use the old emulation of
+  the variadic consturctors define
+  `BOOST_UNORDERED_DEPRECATED_PAIR_CONSTRUCT`.
+
+[h2 Boost 1.49.0]
+
+* Fix warning due to accidental odd assignment.
+* Slightly better error messages.
+
+[h2 Boost 1.50.0]
+
+* Fix equality for `unordered_multiset` and `unordered_multimap`.
+* [@https://svn.boost.org/trac/boost/ticket/6857 Ticket 6857]:
+  Implement `reserve`.
+* [@https://svn.boost.org/trac/boost/ticket/6771 Ticket 6771]:
+  Avoid gcc's `-Wfloat-equal` warning.
+* [@https://svn.boost.org/trac/boost/ticket/6784 Ticket 6784]:
+  Fix some Sun specific code.
+* [@https://svn.boost.org/trac/boost/ticket/6190 Ticket 6190]:
+  Avoid gcc's `-Wshadow` warning.
+* [@https://svn.boost.org/trac/boost/ticket/6905 Ticket 6905]:
+  Make namespaces in macros compatible with `bcp` custom namespaces.
+  Fixed by Luke Elliott.
+* Remove some of the smaller prime number of buckets, as they may make
+  collisions quite probable (e.g. multiples of 5 are very common because
+  we used base 10).
+* On old versions of Visual C++, use the container library's implementation
+  of `allocator_traits`, as it's more likely to work.
+* On machines with 64 bit std::size_t, use power of 2 buckets, with Thomas
+  Wang's hash function to pick which one to use. As modulus is very slow
+  for 64 bit values.
+* Some internal changes.
+
+[h2 Boost 1.51.0]
+
+* Fix construction/destruction issue when using a C++11 compiler with a
+  C++03 allocator ([ticket 7100]).
+* Remove a `try..catch` to support compiling without exceptions.
+* Adjust SFINAE use to try to supprt g++ 3.4 ([ticket 7175]).
+* Updated to use the new config macros.
+
+[h2 Boost 1.52.0]
+
+* Faster assign, which assigns to existing nodes where possible, rather than
+  creating entirely new nodes and copy constructing.
+* Fixed bug in `erase_range` ([ticket 7471]).
+* Reverted some of the internal changes to how nodes are created, especially
+  for C++11 compilers. 'construct' and 'destroy' should work a little better
+  for C++11 allocators.
+* Simplified the implementation a bit. Hopefully more robust.
+
+[h2 Boost 1.53.0]
+
+* Remove support for the old pre-standard variadic pair constructors, and
+  equality implementation. Both have been deprecated since Boost 1.48.
+* Remove use of deprecated config macros.
+* More internal implementation changes, including a much simpler
+  implementation of `erase`.
+
+[h2 Boost 1.54.0]
+
+* Mark methods specified in standard as `noexpect`. More to come in the next
+  release.
+* If the hash function and equality predicate are known to both have nothrow
+  move assignment or construction then use them.
+
+[h2 Boost 1.55.0]
+
+* Avoid some warnings ([ticket 8851], [ticket 8874]).
+* Avoid exposing some detail functions via. ADL on the iterators.
+* Follow the standard by only using the allocators' construct and destroy
+  methods to construct and destroy stored elements. Don't use them for internal
+  data like pointers.
+
+[h2 Boost 1.56.0]
+
+* Fix some shadowed variable warnings ([ticket 9377]).
+* Fix allocator use in documentation ([ticket 9719]).
+* Always use prime number of buckets for integers. Fixes performance
+  regression when inserting consecutive integers, although makes other
+  uses slower ([ticket 9282]).
+* Only construct elements using allocators, as specified in C++11 standard.
+
+[h2 Boost 1.57.0]
+
+* Fix the `pointer` typedef in iterators ([ticket 10672]).
+* Fix Coverity warning
+  ([@https://github.com/boostorg/unordered/pull/2 GitHub #2]).
+
+[h2 Boost 1.58.0]
+
+* Remove unnecessary template parameter from const iterators.
+* Rename private `iterator` typedef in some iterator classes, as it
+  confuses some traits classes.
+* Fix move assignment with stateful, propagate_on_container_move_assign
+  allocators ([ticket 10777]).
+* Fix rare exception safety issue in move assignment.
+* Fix potential overflow when calculating number of buckets to allocate
+  ([@https://github.com/boostorg/unordered/pull/4 GitHub #4]).
+
+[h2 Boost 1.62.0]
+
+* Remove use of deprecated `boost::iterator`.
+* Remove `BOOST_NO_STD_DISTANCE` workaround.
+* Remove `BOOST_UNORDERED_DEPRECATED_EQUALITY` warning.
+* Simpler implementation of assignment, fixes an exception safety issue
+  for `unordered_multiset` and `unordered_multimap`. Might be a little slower.
+* Stop using return value SFINAE which some older compilers have issues
+  with.
+
+[h2 Boost 1.63.0]
+
+* Check hint iterator in `insert`/`emplace_hint`.
+* Fix some warnings, mostly in the tests.
+* Manually write out `emplace_args` for small numbers of arguments -
+  should make template error messages a little more bearable.
+* Remove superfluous use of `boost::forward` in emplace arguments,
+  which fixes emplacing string literals in old versions of Visual C++.
+* Fix an exception safety issue in assignment. If bucket allocation
+  throws an exception, it can overwrite the hash and equality functions while
+  leaving the existing elements in place. This would mean that the function
+  objects wouldn't match the container elements, so elements might be in the
+  wrong bucket and equivalent elements would be incorrectly handled.
+* Various reference documentation improvements.
+* Better allocator support ([ticket 12459]).
+* Make the no argument constructors implicit.
+* Implement missing allocator aware constructors.
+* Fix assigning the hash/key equality functions for empty containers.
+* Remove unary/binary_function from the examples in the documentation.
+  They are removed in C++17.
+* Support 10 constructor arguments in emplace. It was meant to support up to 10
+  arguments, but an off by one error in the preprocessor code meant it only
+  supported up to 9.
+
+[h2 Boost 1.64.0]
+* Initial support for new C++17 member functions:
+  `insert_or_assign` and `try_emplace` in `unordered_map`,
+* Initial support for `merge` and `extract`.
+  Does not include transfering nodes between
+  `unordered_map` and `unordered_multimap` or between `unordered_set` and
+  `unordered_multiset` yet. That will hopefully be in the next version of
+  Boost.

+
+[section:move Move emulation]
+
+Support for move semantics is implemented using Boost.Move. If rvalue
+references are available it will use them, but if not it uses a close,
+but imperfect emulation. On such compilers:
+
+* Non-copyable objects can be stored in the containers.
+  They can be constructed in place using `emplace`, or if they support
+  Boost.Move, moved into place.
+* The containers themselves are not movable.
+* Argument forwarding is not perfect.
+
+[endsect]
+
+[section:allocator_compliance Use of allocators]
+
+C++11 introduced a new allocator system. It's backwards compatible due to
+the lax requirements for allocators in the old standard, but might need
+some changes for allocators which worked with the old versions of the
+unordered containers.
+It uses a traits class, `allocator_traits` to handle the allocator
+adding extra functionality, and making some methods and types optional.
+During development a stable release of
+`allocator_traits` wasn't available so an internal partial implementation
+is always used in this version. Hopefully a future version will use the
+standard implementation where available.
+
+The member functions `construct`, `destroy` and `max_size` are now
+optional, if they're not available a fallback is used.
+A full implementation of `allocator_traits` requires sophisticated
+member function detection so that the fallback is used whenever the
+member function call is not well formed.
+This requires support for SFINAE expressions, which are available on
+GCC from version 4.4 and Clang.
+
+On other compilers, there's just a test to see if the allocator has
+a member, but no check that it can be called. So rather than using a
+fallback there will just be a compile error.
+
+`propagate_on_container_copy_assignment`,
+`propagate_on_container_move_assignment`,
+`propagate_on_container_swap` and
+`select_on_container_copy_construction` are also supported.
+Due to imperfect move emulation, some assignments might check
+`propagate_on_container_copy_assignment` on some compilers and
+`propagate_on_container_move_assignment` on others.
+
+The use of the allocator's construct and destruct methods might be a bit
+surprising.
+Nodes are constructed and destructed using the allocator, but the elements
+are stored in aligned space within the node and constructed and destructed
+by calling the constructor and destructor directly.
+
+In C++11 the allocator's construct function has the signature:
+
+    template <class U, class... Args>
+    void construct(U* p, Args&&... args);
+
+which supports calling `construct` for the contained object, but
+most existing allocators don't support this. If member function detection
+was good enough then with old allocators it would fall back to calling
+the element's constructor directly but in general, detection isn't good
+enough to do this which is why Boost.Unordered just calls the constructor
+directly every time. In most cases this will work okay.
+
+`pointer_traits` aren't used. Instead, pointer types are obtained from
+rebound allocators, this can cause problems if the allocator can't be
+used with incomplete types. If `const_pointer` is not defined in the
+allocator, `boost::pointer_to_other<pointer, const value_type>::type`
+is used to obtain a const pointer.
+
+[endsect]
+
+[section:pairs Pairs]
+
+Since the containers use `std::pair` they're limited to the version
+from the current standard library. But since C++11 `std::pair`'s
+`piecewise_construct` based constructor is very useful, `emplace`
+emulates it with a `piecewise_construct` in the `boost::unordered`
+namespace. So for example, the following will work:
+
+    boost::unordered_multimap<std::string, std::complex> x;
+
+    x.emplace(
+        boost::unordered::piecewise_construct,
+        boost::make_tuple("key"), boost::make_tuple(1, 2));
+
+Older drafts of the standard also supported variadic constructors
+for `std::pair`, where the first argument would be used for the
+first part of the pair, and the remaining for the second part.
+
+[endsect]
+
+[section:misc Miscellaneous]
+
+When swapping, `Pred` and `Hash` are not currently swapped by calling
+`swap`, their copy constructors are used. As a consequence when swapping
+an exception may be throw from their  copy constructor.
+
+Variadic constructor arguments for `emplace` are only used when both
+rvalue references and variadic template parameters are available.
+Otherwise `emplace` can only take up to 10 constructors arguments.

-In
-[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2387.pdf
-N2387, Omnibus Allocator Fix-up Proposals],
-Pablo Halpern suggests that there are actually two distinct allocator models,
-"Moves with Value" and "Scoped" which behave differently:
-
-[:
-When allocators are allowed to have state, it is necessary to have a model for
-determining from where an object obtains its allocator. We’ve identified two such
-models: the “Moves with Value” allocator model and the “Scoped” allocator model.
-
-In the “Moves with Value” allocator model, the copy constructor of an allocator-aware
-class will copy both the value and the allocator from its argument. This is the model
-specified in the C++03 standard. With this model, inserting an object into a container
-usually causes the new container item to copy the allocator from the object that was
-inserted. This model can be useful in special circumstances, e.g., if the items within a
-container use an allocator that is specially tuned to the item’s type.
-
-In the “Scoped” allocator model, the allocator used to construct an object is determined
-by the context of that object, much like a storage class. With this model, inserting an
-object into a container causes the new container item to use the same allocator as the
-container. To avoid allocators being used in the wrong context, the allocator is never
-copied during copy or move construction. Thus, it is possible using this model to use
-allocators based on short-lived resources without fear that an object will transfer its
-allocator to a copy that might outlive the (shared) allocator resource. This model is
-reasonably safe and generally useful on a large scale. There was strong support in the
-2005 Tremblant meeting for pursuing an allocator model that propagates allocators
-from container to contained objects.
-]
-
-With these models the choice becomes clearer:
-
-[:
-I introduced the “Moves with Value” allocator model and the
-“Scoped” allocator model. In the former case, the allocator is copied when the container
-is copy-constructed. In the latter case it is not. Swapping the allocators is the right thing
-to do if the containers conform to the “Moves with Value” allocator model and
-absolutely the wrong thing to do if the containers conform to the “Scoped” allocator
-model. With the two allocator models well-defined, the desired behavior becomes clear.
-]
-
-The proposal is that allocators are swapped if the allocator follows the
-"Moves with Value" model and the allocator is swappable. Otherwise a slow swap
-is used. Since containers currently only support the "Moves with Value" model
-this is consistent with the committee's current recommendation (although it
-suggests using a trait to detect if the allocator is swappable rather than a
-concept).
-
-Since there is currently neither have a swappable trait or concept for
-allocators this implementation always performs a slow swap.
-
-[h3 Are insert and erase stable for unordered_multiset and unordered_multimap?]
