      [ENHANCEMENTS]

      - The "list" command now has a --all option that causes it to list
      every package in every distribution in the repository, including past
      releases and distributions that are not currently registered on any
      stack.  When using the --all option, the output includes two extra flags:
      "m" means that the package is considered to be the main module in the
      distribution. "x" means that the package can be included in the index.
      For both of these, the flags will appear as "-" when they are false.

      - The --packages, --distributions, and --authors filtering options on
      the "list" command are now treated as regular expressions.  Take care
      to quote them if you use any special shell metacharacters.

      [BUG FIXES]

      - Fixed regression in the "pin", "unpin", and "unregister" commands
      which resulted in a warning from DBIx::Class about returning multiple
      rows for a find() query.
