Potentially breaking changes
----------------------------

- The algorithm for ``multi{map,set}::find`` has been modified, which doesn't guarantee that the first element is
returned. If code relies on the first element being returned from ``find`` it may be broken. To fix it use
``lower_bound`` or ``equal_range`` instead.
