  Rafael Mendonça França

• Fix String#safe_constantize throwing a LoadError for incorrectly cased constant references.

  Keenan Brock

  fetch_multi(*names) now returns its results in the same order as the *names requested, rather than returning cache hits followed by cache misses.

  Gannon McGibbon

• If the same block is included multiple times for a Concern, an exception is no longer raised.

  Mark J. Titorenko, Vlad Bokov

• Fix bug where #to_options for ActiveSupport::HashWithIndifferentAccess
  would not act as alias for #symbolize_keys.

  Nick Weiland

• Improve the logic that detects non-autoloaded constants.

  Jan Habermann, Xavier Noria

• Deprecate ActiveSupport::Multibyte::Unicode#pack_graphemes(array) and ActiveSuppport::Multibyte::Unicode#unpack_graphemes(string)
  in favor of array.flatten.pack("U*") and string.scan(/\X/).map(&:codepoints), respectively.

  Francesco Rodríguez

• Deprecate ActiveSupport::Multibyte::Chars.consumes? in favor of String#is_utf8?.

  Francesco Rodríguez

• Fix duration being rounded to a full second.

    time = DateTime.parse("2018-1-1")
    time += 0.51.seconds
  

  Will now correctly add 0.51 second and not 1 full second.
