+
+* The original version made heavy use of macros to sidestep some of the older

+  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.

-Matt Austern suggests removing the `construct`, `destroy` and `address` member

 [h3 Swapping containers with unequal allocators]
 
 It isn't clear how to swap containers when their allocators aren't equal.
 This is 
 [@http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#431
-Issue 431: Swapping containers with unequal allocators].
-
-Howard Hinnant wrote about this in
-[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1599.html N1599]
-and suggested swapping both the allocators and the containers' contents.
-But the committee have now decided that `swap` should do a fast swap if the
-allocator is Swappable and a slow swap using copy construction otherwise. To
-make this distinction requires concepts.
-
-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.
+Issue 431: Swapping containers with unequal allocators]. This has been resolved
+with the new allocator specification, so this should be fixed when
+support is added.
 
 [h3 Are insert and erase stable for unordered_multiset and unordered_multimap?]
 
-It is not specified if `unordered_multiset` and `unordered_multimap` preserve the order
+It wan't specified if `unordered_multiset` and `unordered_multimap` preserve the order
 of elements with equivalent keys (i.e. if they're stable under `insert` and `erase`).
-This is [@http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-active.html#518 issue 581].
-The current proposal is that insert, erase and rehash are stable - so they are here.
-
-[h3 const_local_iterator cbegin, cend missing from TR1]
-
-[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2482.html#691
-Issue 691] is that `cbegin` and `cend` are missing for local iterators.
-The current resolution is that they'll be added, so I've added them.
-
-[h2 Future Developments]
-
-[h3 Support for `emplace`]
-
-In __n2369__ a new member function, `emplace` was added to the containers to
-allow placement insert, as described in __n2345__. To fully implement this
-`std::forward` is required, along with new functions in `std::allocator` and
-new constructors in `std::pair`. But partial support is possible - especially
-if I don't use the `construct` member of allocators.
-
-[h3 Equality operator]
-
-While `operator==` and `operator!=` are not included in the standard, it's
-possible to implement them for all the containers - this is helped by having
-stable order of elements with equivalent keys. They will need to be specified
-differently to the standard associative containers, probably comparing keys
-using the equality predicate rather than `operator==`. This is inconsistent
-with the other containers but it is probably closer to user's expectations.
-
-If these are added then a `hash_value` free function should also be added.
+Since [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2691.pdf
+n2691] it's been specified that they do and this implementation follows that.
