+- msh(1) is deprecated and will be removed from the next release.
+- spost(8) has been merged into post(8). Its functionality is enabled
+ by selecting the sendmail/pipe mail transport method, described in
+ the mh-tailor(5) man page. The spost -noalias, -backup/-nobackup,
+ -push/-nopush, and -remove/-noremove switches are not supported by
+ post. Note that spost did not support -whom or Dcc, and neither
+ does post when using sendmail/pipe. And spost would expand blind
+ aliases and send them in the message; post with sendmail/pipe
+ refuses to do that. For backward compatibility, spost has been
+ replaced by a simple shell script that exec's post -mts
+ sendmail/pipe.
+- Support for the undocumented and deprecated --enable-nmh-debug configure
+ flag has been removed.
+- Support for encoding some characters designated as EBCDIC-unsafe
+ via the -ebcdicsafe and -noebcdicsafe switches to mhbuild has
+ been removed.
+- The configure flag --with-pager has been removed; the default pager
+ is now hardcoded as "more". Users are still free to override the
+ default using the PAGER environment variable or entries in .mh_profile.
+- The configure flag --with-editor has been removed; the fallback editor
+ if none is configured is "vi".
