+These and a few other bad block handling methods are getting disorganized. They
+will be replaced by a series of --bb=METHOD options (see 'nanddump --help').
+
+In addition, the previous default bad block behavior was to dump 0xFF in place
+of bad blocks. This was not a good "inverse operation" of nandwrite. Thus, the
+current default behavior has become the (new) option --bb=padbad, and in 1.4.6,
+the default will be --bb=skipbad.
+
+All of these changes will occur in 1.4.6. For now, there are appropriate
+deprecation warning messages and an alert telling about the soon-to-be-default
+options.
