From the NEWS file:

    - Added the ability for Mailman generated passwords (both member and list
      admin) to be more cryptographically secure.  See new configuration
      variables USER_FRIENDLY_PASSWORDS, MEMBER_PASSWORD_LENGTH, and
      ADMIN_PASSWORD_LENGTH.  Also added a new bin/withlist script called
      reset_pw which can be used to reset all member passwords.  Passwords
      generated by Mailman are now 8 characters by default for members, and 10
      characters for list administrators.

+"""Reset the passwords for members of a mailing list.
+
+This script resets all the passwords of a mailing list's members.  It can also
+be used to reset the lists of all members of all mailing lists, but it is your
+responsibility to let the users know that their passwords have been changed.
+
+This script is intended to be run as a bin/withlist script, i.e.
+
+% bin/withlist -l -r reset_pw [options]
+
+Options:
+    -v / --verbose
+        Print what the script is doing.
