I couldn't find any though. commit c409b6f30373535b6eed92e55d4695688d32be9e removes unnecessary constraints from ghc maintained libraries, and silences the redundant-constraints warnings from the other libraries containers, haskeline and transformers. I couldn't find anything related to binary though, nor any warnings in the build log. If there are any, please let me know, or file a bug at http://github.com/kolmodin/binary Thanks!
