• Add --nohidden option.
• Add --permissions option.
• Add --order option.
• Add --reverse option.
• Add --immediate option.
• Speed up file comparison.
• Fix bug where fdupes fails to consistently ignore hardlinks, depending on
  file processing order, when F_CONSIDERHARDLINKS flag is not set.
• Fix bug in is_hardlink(): Proper traversal of duplicates is done via
  dupe->duplicates, not via dupe->next.

fdupes 1.51

Changes from 1.50 to 1.51:

• Added support for 64-bit file offsets on 32-bit systems.
• Using tty for interactive input instead of regular stdin. This is to
  allow feeding filenames via stdin in future versions of fdupes without
  breaking interactive deletion feature.
• Fixed some typos in --help.
• Turned C++ style comments into C style comments.
