Eek, meant to import 3.23, not 3.20.  Since this is an update, ChangeLog:
=====

        * Safeguards against trying to use greater edit distance
          than the pattern is long, inspired by 'idallen'.

        * Advise against using String::Approx for text comparisons,
          since String::Approx is meant for strings.

        * Released as 3.23.

        * adistr($pattern, @inputs) returned absolute, not relative,
          distances in list context, reported by 'idallen'.

        * Released as 3.22.

        * asubstitute() didn't substitute in $_ as promised,
          reported by Tim Maher.

        * Released as 3.21.
