   Gisle Aas (6):
      Less noisy 'git status' output
      Merge pull request #1 from schwern/bug/require_eval
      Don't clobber $@ in Digest->new [RT#50663]
      More meta info added to Makefile.PL
      Fix typo in RIPEMD160 [RT#50629]
      Add schwern's test files

   Michael G. Schwern (5):
      Turn on strict.
      Convert tests to use Test::More
      Untabify
      Turn Digest::Dummy into a real file which exercises the Digest->new() require logic.
