Here's the latest snapshot:

The distinction between the cut changes (classified as bug fixes)
and the stty change is, um... subtle.

And here are the NEWS entries:

    ** Bug fixes

      cut now diagnoses a range starting with zero (e.g., -f 0-2) as invalid;
      before, it would treat it as if it started with 1 (-f 1-2).

      "cut -f 2-0" now fails; before, it was equivalent to "cut -f 2-"

      cut now diagnoses the '-' in "cut -f -" as an invalid range, rather
      than interpreting it as the unlimited range, "1-".
      ...

    ** Improved robustness

      stty no longer silently accepts certain invalid hex values
      in its 35-colon commmand-line argument
