- Fixed bug on bug endian platforms which produced incorrect results in ``StataReader`` (:issue:`8688`).

- Bug in ``MultiIndex.has_duplicates`` when having many levels causes an indexer overflow (:issue:`9075`, :issue:`5873`)
- Bug in ``pivot`` and `unstack`` where ``nan`` values would break index alignment (:issue:`7466`)
