- Update iterator_facade test for #1019 (header change already merged). - Category of each iterator is reduced to a known category before we try to find a minimum. Fixes #1517. - `function_input_iterator` from Dean Michael Berris. Fixes #2893 - Fix typo in `boost/iterator.hpp`. Fixes #3434. - Always include `add_reference` header in iterator adaptor header. Did not merge changes for #1427. [SVN r70709]
