-Backward incompatibilities:
-- Changed exit status of each nmh command's -version and -help
- switches from 1 to 0.
-- The following environment variables were deprecated in nmh 1.5
- and are removed from this release:
- MHPOPDEBUG (use -snoop command line switch instead)
- MM_NOASK (use -nolist and -nopause command line switches instead)
- NOMHNPROC (use -nocheckmime command line switch instead)
- FACEPROC (undocumented faceproc feature removed)
-- Changed repl and dist default to -noatfile. The default of -atfile
- was deprecated in nmh 1.5. If there are no requests to maintain
- -atfile, it will be removed in the future.
+------------
+NEW FEATURES
+------------
+
+- The default editor has been changed from 'vi' to 'prompter', to align with
+ historical practice and reduce packaging dependencies on external programs.
+- A new -checkbase64 switch to mhfixmsg(1).
+- inc(1)/msgchk(1) now support STARTTLS for the POP protocol.
+
+-----------------
+OBSOLETE FEATURES
+-----------------
+
+- The MIME content cache functionality has been mostly non-functional since
+ the development on nmh, and consequently all of the content caching code
+ and related switches (-cache/-rcache/-wcache) have been removed.
+- Support for generating and reassembling message/partial messags has been
+ removed; it seems that this has been broken since 1.5 and there is very
+ little support across MUAs.
+
+-------------------
+DEPRECATED FEATURES
+-------------------
+
+- The generation and verification of Content-MD5 headers is no longer
+ performed. The -check and -nocheck switches to various nmh programs
+ that would control this functionality still exist, but are non-functional
+ and will be removed in the next release.
+
+---------
+BUG FIXES
+---------
+
+- Fixed bcc to work with sendmail/pipe, and better documented that dcc
+ doesn't work with it [Bug 55700].
+- An -attendee switch has been added to mhical(1), for use when more than one
+ (or zero) attendees match a user's mailbox.
+- Fixed inc(1) and %(me) function escape to not obey Local-Mailbox profile
+ component.
