    [ADDED]

    - Added the 'digest' method to produce a hexadecimal SHA-256
      (or user-specified) digest of a file

    [FIXED]

    - Fixed bug where lines() with a count longer than the
      file would return undef for the extra lines.  Now returns
      only the lines in the file if the count is greater than
      the number of lines.

    [FIXED]

    - Spew to an existing symlink now atomically replaces
      the resolved destination, not the symlink
