@ -175,4 +175,21 @@ C++11 support has resulted in some breaking changes:
* Fix warning due to accidental odd assignment.
* Slightly better error messages.
[h2 Boost 1.50.0]
* Fix equality for `unordered_multiset` and `unordered_multimap`.
* [@http://svn.boost.org/trac/boost/ticket/6771 Ticket 6771]:
Avoid gcc's `-Wfloat-equal` warning.
* [@http://svn.boost.org/trac/boost/ticket/6784 Ticket 6784]:
Fix some Sun specific code.
* 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.
