Things to add to the release notes for the next full release:
-- 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 to the message being replied
- or redistributed named ./@. 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.

+NEW FEATURES
+------------
+
+- builds use OpenSSL if available.
+- post now defaults to port 587 on 'smtp' message submission.
+- A value of 0 for the width switch of scan(1), inc(1), ap(1), dp(1),
+ fmttest(1), and mhl(1) now means as many characters as the format
+ engine can produce [Bug #15274]. That amount is limited by internal
+ buffers.
+- If a component has trailing whitespace, e.g., body:component="> ",
+ mhl now trims that whitespace off when filtering blank text lines.
+- An "rtrim" flag has been added to mhl to remove any trailing
+ whitespace from filtered text lines. A corresponding "nortrim" flag
+ has also been added.
+- The default locations for configuration files and suppoooort binaries
+ have been changed. Configuration files now install into ${sysconfdir}/nmh,
+ and support binaries are placed in ${libexecdir}/nmh. If you are upgrading
+ an existing installation you should look for old configuration files in
+ ${sysconfdir} and merge any local customizations into the new files in
+ ${sysconfdir}/nmh, then remove the old files. ${libdir} will also contain
+ obsolete support programs that should be removed.
+- When building from source, configure will derive ${prefix} from an existing
+ nmh installation if it finds one in your $PATH.
+- Added getmymbox and getmyaddr mh-format(5) function escapes.
+- New -[no]changecur, -fixtype, -decodetypes, and -[no]crlflinebreaks switches
+ have been added to mhfixmsg(1).
+- mhfixmsg now removes an extraneous trailing semicolon from header
+ parameter lists.
+- Added -convertargs switch to repl(1), to pass arguments to programs
+ specified in the user's profile or mhn.defaults to convert message
+ content.
+- Added mhical(1), to display, reply to, and cancel iCalendar (RFC 5545)
+ event requests.
+- added multiply format function
+- "mhparam bindir" prints the path to the directory containing the public
+ executables (${bindir}).
+- new "-prefer" switch for mhshow (and mhlist and mhshow), to allow specifying
+ the preferred content types to show, if present in a multipart alternative.
+- mh-format now has %(kilo) and %(kibi) functions, to allow printing
+ numbers as, for example, "10K", or "2.3Mi"
+- Support for the -sendmail flag to send/post to change the sendmail
+ binary when using the sendmail/pipe MTS.
+- Added support to send(1) to specify switches to post(1) based on address or
+ domain name in From: header line in message draft.
+- post(8) -snoop now attempts to decode base64-encoded SMTP traffic.
+- folder(1) -nocreate now prints a warning message for a non-existent folder.
+- mhfixmsg(1) now allows -decodetext binary, though 8bit is still the default.
+- inc(1) and msgchk(1) now support TLS encryption natively.
+- Support for SMTPUTF8 (RFC 6531) has been added. mhshow(1) already supported
+ RFC 6532, assuming all 8-bit message header field bodies are UTF-8 and use
+ of a UTF-8 locale.
+- mhfixmsg now replaces RFC 2047 encoding with RFC 2231 encoding of name and
+ filename parameters in Content-Type and Content-Disposition headers,
+ respectively.
+- If a message body contains 8-bit bytes, post(8) uses SMTP 8BITMIME if the
+ server supports it. If not, post fails with a message to the user to
+ encode the message for 7-bit transport.
+- Added welcome message when nmh detects that its version changed.
+- Fewer lseek(2)s will be used when reading headers in the common case.
+- Single-character headers can be reliably formatted, etc., instead of
+ apparently being missing.
+- ./configure's --enable-debug has been removed; it did nothing.
+
+-----------------
+OBSOLETE FEATURES
+-----------------
+
+- The undocumented -queue switch to post was deprecated in nmh 1.6, and was
+ removed in this release.
+- conflict(8) was deprecated in nmh 1.6, and was removed in this release.
+- mhtest(8) was deprecated in nmh 1.6, and was removed in this release.
+- msh(1) was deprecated in nmh 1.6, and was removed in this release.
+- Support in alias files for the the "*" address-group (everyone) was
+ deprecated in nmh 1.6, and was removed in this release.
+
+-------------------
+DEPRECATED FEATURES
+-------------------
+
+- Support for the MHPDEBUG environment variable is deprecated and will be
+ removed from a future nmh release. Instead, use the -debug switch to pick.
+- With the move of support binaries from ${libdir} to ${libexecdir}/nmh, the
+ mostly undocumented 'libdir' mhparam(1) component has been replaced by a
+ new 'libexecdir' component. 'libdir' will be removed in a future release.
+
+---------
+BUG FIXES
+---------
+
+- The format scanner no longer subtracts 1 from the width. This has the
+ effect of no longer counting the trailing newline in the output of
+ scan(1), inc(1), and the other programs that rely on the format scanner.
+- The first character of some very short (less than 4 characters) message
+ bodies is no longer dropped.
+- mhfixmsg now adds a Content-Transfer-Encoding header at the message level,
+ if needed after decoding text parts.
+- mhbuild now checks whether all text parts need a Content-Transfer-Encoding
+ header, not just those with a character set not specified.
