Things to add to the release notes for the next full release:
-- SASL security layers (encryption) are now supported for the SMTP MTA.
-- You can now select the SMTP server and port from either "send" or a
- user's mh_profile (you could always select the server; that option is
- now documented). These are available via the -server and -port switches.
-- All networking code has been modified to use the new networking APIs
- (getaddrinfo and friends). All networking code (with the exception of
- the ftp client) now supports IPv6.
-- Support for prefixing a \01 in the "servers" entry in mts.conf to
- connect to all servers on a particular named net has been removed.
-- New commands 'new', 'fnext', 'fprev', and 'unseen' for showing folders with
- unseen mail (or mail in any specified sequence), changing to next such
- folder, changing to previous such folder, and scanning all such folders,
- respectively. This is based on Luke Mewburn's 'new':

+- Switched to buffered output when performing TLS encryption in the SMTP
+ MTA to increase performance.
+- mh-e support has been changed so that it is always compiled into nmh;
+ old features that were previously enabled by the MHE option have been
+ garbage collected.
+- Old code enabled by the UCI preprocessor definition has been
+ garbage-collected.
+- LOCKDIR is now configurable via --enable-lockdir
+- All configuration options that were formerly only adjustable via editing
+ config.h have been removed.
+- Support for the built-in ftp client (used when dealing with external body
+ message parts in MIME messages) has been removed.
+- fileproc and mhlproc mh-profile entries will now be obeyed by
+ send, rcvdist, and whatnow.
+- New mh-format(5) instructions have been implemented: %(putlit),
+ %(concataddr), %(myhost), %(myname)
+- The --enable-pop configure option has been removed; POP support is now
+ compiled in always.
+- You can now filter the body of a message through a user-defined filter
+ program inside of repl (the idea is that it will be used by repl).
+ See mhl(1), specifically the "format" keyword and "formatproc" in
+ mh-profile(5).
+- The test suite has been integrated into the Makefile via "make check".
+- The following environment variables are obsolete/deprecated. Support for
+ them will be removed from the next nmh 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 to be removed)
+- nmh's idea of the local mailbox is available via a new mh-profile(5)
+ escape, %(localmbox). The local mailbox name is now configurable
+ via a new mh-profile(5) entry, Local-Mailbox.
+- comp, forw, and dist all support -from, -to, -cc, -fcc, and -subject
+ switches. They also all process all component templates through
+ mh-format(5).
+- post(8) now requires a From: header in all drafts that it processes
+ for sending. The default component templates have all been adjusted
+ to include appropriate From: headers based on either the -from switch
+ or the local mailbox.
+- burst(1) now supports any valid message delimiter according to RFC 934.
+- A problem with the MD5 digest calculator on 64-bit systems has been fixed.
+- Fixed mhbuild -check to properly insert Content-MD5 header.
+- Fixed mhlist -verbose to work with all content types [Bug #35219].
+- Fixed file descriptor leaks in mhparse [Bug #24004: (debbug 344182)].
+- Fixed mhstore to honor nmh-storage profile entry even with -auto
+ [Bug #35303].
+- post(8) can now explicitly control the SMTP envelope address either via
+ the Sender: header or the new Envelope-From: header.
+- The -attach option is now the default (using Nmh-Attachment) and
+ -attachformat 1 is now the default.
+- repl and dist currently create a link named ./@ to the message being
+ replied or redistributed. A switch, -noatfile, has been added to
+ disable creation of this link. The current default behavior can
+ also be specified with -atfile. The current default behavior is
+ obsolete/deprecated: -noatfile will become the default in the next
+ nmh release. If there are no requests to maintain -atfile, it will
+ be removed in the future.
+- Added support for readline editing and command/filename completion at
+ the WhatNow? prompt
+- The hostable option of mts.conf is no longer needed and has been removed.
+- A sample mhl filter for handling MIME content inside of mhl has been
+ placed in the doc directory as "replyfilter".
