+# NEWS - Release notes for nmh 1.7
+#
+
+Welcome to nmh, the new version of the classic MH mail handling system.
+It's been over three years since the last release of nmh, and there have
+been a number of significant changes since the last release. Long-time
+MH and nmh uses should read careful the NOTEABLE CHANGES section, as there
+are some significant changes to nmh behavior. Otherwise, please see the
+README and INSTALL files for help on getting started with nmh.
+
+---------------
+NOTABLE CHANGES
+---------------
+
+The largest notable changes in the 1.7 release are:
+
+- Complete unification of network security support. All network protocols
+ (currently, POP and SMTP) have been refactored to use a common set of
+ security routines. This means all protocols support all SASL mechanisms
+ (via the Cyrus-SASL library) and TLS. TLS support has been strengthened
+ to perform certificate name validation and to require TLS 1.1 as a
+ minimum protocol. Also, all protocols can make use of the OAuth2/XOAUTH
+ SASL mechanism, which is supported by gmail.
+- send(1) now supports adding switches to post(8) based on the address or
+ domain of the email address in the From: header; this more easily allows
+ users to support multiple identities.
+- A generic facility for passing arguments to filter programs in repl(1)
+ by use of the -convertargs switch.
+- Native support for the manipulation of iCalendar requests; see mhical(1)
+ for more details.
+
+------------
+NEW FEATURES
+------------
+
+The following are new features for the 1.7 release of nmh:
+
+- When building from source, configure will derive ${prefix} from an existing
+ nmh installation if it finds one in your $PATH.
+- Added welcome message when nmh detects that its version changed.
+- The default locations for configuration files and support 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. ${libdir} will also contain
+ obsolete support programs that should be removed.
+- All TLS connections now perform certificate validation (including hostname
+ matching) by default; can be disabled on a per-application basis.
+- post now defaults to port 587 on 'smtp' message submission.
+- A value of 0 for the width switch of scan(1), inc(1), ap(1), dp(1),
+ fmttest(1), and mhl(1) now means as many characters as the format
+ engine can produce [Bug #15274]. That amount is limited by internal
+ buffers.
+- If a component has trailing whitespace, e.g., body:component="> ",
+ mhl now trims that whitespace off when filtering blank text lines.
+- An "rtrim" flag has been added to mhl to remove any trailing
+ whitespace from filtered text lines. A corresponding "nortrim" flag
+ has also been added.
+- Added getmymbox and getmyaddr mh-format(5) function escapes.
+- New -[no]changecur, -fixtype, -decodetypes, and -[no]crlflinebreaks switches
+ have been added to mhfixmsg(1).
+- mhfixmsg now removes an extraneous trailing semicolon from header
+ parameter lists.
+- Added -convertargs switch to repl(1), to pass arguments to programs
+ specified in the user's profile or mhn.defaults to convert message
+ content.
+- Added mhical(1), to display, reply to, and cancel iCalendar (RFC 5545)
+ event requests.
+- added multiply format function
+- "mhparam bindir" prints the path to the directory containing the public
+ executables (${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.
+- All network protocols support the XOAUTH authentication mechanism.
+- 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.
+- 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.
+- configure now defaults to enabling each of TLS and Cyrus SASL if the
+ necessary headers and libraries are found.
+- Moved build_nmh to top-level directory.
+- Better error reporting for connections to network services
+
+---------
+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.
+- mhbuild no longer parses lines that start with # as directives with
+ -nodirectives.
+- repl now makes sure that any Fcc header in a replied-to message is not
+ copied into the outgoing draft by default, and that the -fcc switch
+ actually works in the absence of a Fcc header in the replied-to message.
+- A Content-ID is generated for message/external-body entities as required
+ by RFC 2045, even if -nocontentid is supplied to mhbuild.
+- post will now expand aliases on a "From" line when doing a BCC [Bug #51098].
+- scan can now handle empty files without violating an assert [Bug #51693].
+
+-------------------
+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.
+
+-----------------
+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.
+- Support for multiple hostnames in the "servers" entry of mts.conf has
+ been removed.
+- Support in alias files for expanding aliases based on group membership
+ (=) and primary group (+) has been removed.
+
+As always, feedback is welcome.

+#
+# NEWS - Release notes for nmh 1.6
+#
+
+Welcome to nmh, the new version of the classic MH mail handling system.
+It's been nearly two years since the last release of nmh, and there have
+been a number of significant changes since the last release. Long-time
+MH and nmh uses should read careful the NOTEABLE CHANGES section, as there
+are some significant changes to nmh behavior. Otherwise, please see the
+README and INSTALL files for help on getting started with nmh.
+
+------------
+NEW FEATURES
+------------
+
+The following are new features for the 1.6 release of nmh:
+
+- All nmh programs will now warn about multiple profile entries for
+ the same non-null, non-comment component. In previous versions, all
+ but the first were silently ignored.
+- mhmail now supports all post(8) options, or optionally can use
+ send(1) with all of its options. Its formerly undocumented -resent
+ switch has been documented. And it has new -attach, -headerfield,
+ and -send/-nosend switches.
+- Default to flock() locking on OpenBSD and Darwin.
+- Added -directives support to mhbuild(1) to control whether or not
+ mhbuild will honor MIME directives by default. And added support
+ for special #on/#off/#pop directives to control the MIME directive
+ processing state.
+- Added -messageid switch to send(1) and post(8). This allows
+ selection of the style to use for generated Message-ID and
+ Content-ID header fields. The default localname style is
+ pid.time@localname, where time is in seconds, and matches previous
+ behavior. The random style replaces the localname with some
+ (pseudo)random bytes and uses microsecond-resolution time.
+- Added -clobber switch to mhstore(1) to control overwriting of
+ existing files.
+- Added -outfile switch to mhstore(1).
+- Added -noall/-all switches to sortm(1). sortm -noall requires
+ a messages argument.
+- $PAGER overrides the compiled-in default pager command.
+- Added etc/scan.highlighted format file, as an example of how to
+ highlight/colorize the output of scan(1).
+- inc(1) now supports a -port switch to specify the port used by the
+ POP server.
+- pick(1) now decodes MIME-encoded header fields before searching.
+- The VISUAL and EDITOR environment variables are now supported as fallbacks
+ if the user does not configure an editor entry in their profile.
+- The format engine (mh_format(5)) now properly accounts for multibyte
+ characters when accounting for column widths.
+- burst(1) now can burst MIME-formatted digests (messages that contain
+ message/rfc822 parts instead of messages formatted with RFC 934).
+- All proc entries (showproc, moreproc, etc) can now accept entries that
+ contain spaces and shell metacharacters. If found, such entries will
+ either be space-split or processed by /bin/sh.
+- A new program, fmttest(1) is included to help debug format files. See
+ NOTABLE CHANGES below.
+- mhshow/mhstore now have support for RFC-2017 (access-type=url) for
+ external message bodies.
+- Added -retainsequences switch to refile(1).
+- A new program, mhfixmsg(1), is included to rewrite MIME messages with
+ various transformations. See NOTABLE CHANGES below.
+- Added -[no]rmmproc switches to rmm(1).
+- Added support for Content-Disposition header (RFC 2183) to mhstore(1)
+ and mhn(1) when used with -auto.
+- All nmh commands now support transactional locking for sequence files.
+ See NOTABLE CHANGES below.
+- There is no longer a per-folder maximum number of sequences.
+- For the SMTP MTA TLS can now be negotiated at the beginning of the
+ connection with the -initialtls switch.
+- Messages can now be selected using a relative offset from some other
+ message, or from the start or end of a sequence. See mh-sequence(5).
+- The -changecur and -nochangecur switches have been added to mhlist(1).
+- mhbuild(1) can now encode 8-bit message headers using RFC-2047 encoding
+ rules. See NOTABLE CHANGES below.
+- The whatnow(1) attach feature will determine the content type of an
+ attachment using a program such as file --mime-type, if available at
+ configuration time. If not, it will use mhshow-suffix- entries as
+ before. The -v switch to attach causes it to display the mhbuild
+ directive that send(1) will use.
+- mhbuild(1) now supports the -auto/-noauto flags (to be used by send(1)
+ when invoking mhbuild automatically).
+- mhbuild(1) now is automatically run by send, to insure that all outgoing
+ messages have proper MIME formatting. See NOTABLE CHANGES below.
+- A new header, "Attach", is supported by mhbuild; it is used to replace
+ previous functionality (which by default used a header named
+ Nmh-Attachment). See NOTABLE CHANGES below.
+- The default Content-Transfer-Encoding for text parts is now 8bit.
+- mhbuild(1) now supports a selectable Content-Transfer-Encoding
+- If nmh was configured with iconv(3) support, mhshow will convert, if
+ necessary, the charset of text/plain content to match the user's
+ locale setting. See NOTABLE CHANGES below.
+- Added support for %{charset} display string escape to mhshow(1).
+- The MIME parsing and generating routines now support RFC 2231 extended
+ parameter information.
+- mh-mime(7) now provides an introduction to nmh's MIME handling.
+- mhshow(1) will now by default display all text content under one pager,
+ and display markers for non-text and non-inline content. The content
+ markers are changeable via mh-format(5). See NOTABLE CHANGES below.
+
+-----------------
+OBSOLETE FEATURES
+-----------------
+- 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 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.
+- The undocumented -queue switch to mhmail has been removed.
+- 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. See NOTABLE CHANGES below.
+- 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".
+- The support for the undocumented NOPUBLICSEQ preprocessor definition
+ to disable public sequence support has been removed.
+- Support for the -normalize and -nonormalize switches to the ali(1) and
+ ap(8) commands has been removed.
+- "make install" no longer strips executables. Use "make install-strip"
+ instead.
+- The environment variable MM_CHARSET to indicate the native character
+ set is no longer supported. The native character set will be solely
+ determined by the locale settings.
+- Temporary files are stored in the first non-null location of
+ {MHTMPDIR environment variable, TMPDIR environment variable, MH Path}.
+ They are no longer be stored in the location specified by the TMP
+ environment variable.
+- Instead of printing PostScript attachments, by default, from mhshow,
+ try to find a suitable viewer.
+- Support for parallel display of multipart/parallel content has been
+ removed from mhshow; all multipart content will be displayed in
+ serial.
+- Support for -pause/-nopause switches on mhshow has been removed.
+
+-------------------
+DEPRECATED FEATURES
+-------------------
+- The undocumented -queue switch to post is deprecated/obsolete
+ and will be removed in the next release. It supports the
+ SMTP XQUE verb, which is obsolete according to
+ http://smtpfilter.sourceforge.net/esmtp.html
+- conflict(8) is deprecated and will be removed from the next release.
+- mhtest(8) is deprecated and will be removed from the next release.
+- msh(1) is deprecated and will be removed from the next release.
+- Support in alias files for the the "*" address-group is obsolescent
+ and will be removed in a future release.
+
+---------
+BUG FIXES
+---------
+
+- Replaced utilities that operate on pbm files with those that operate
+ on pnm files in etc/mhn.defaults [Bug #15152].
+- Removed obsolete BUGS section at end of rcvstore(1) man page [Bug #4361].
+- Fixed -nocc me doesn't account for Alternate-Mailboxes [Bug #36635].
+- Propagate Mail-Followup-To [Bug #5571].
+- "mark -sequence cur -delete all" now works for cur as well as any
+ other sequence, to allow clearing of the current message indication.
+- The first alias contained in a blind list is now expanded. The
+ mh-alias(5) man page was updated to show that blind lists must not
+ be terminated with, or contain, a trailing semicolon [Bug #15604].
+- Fixed sendfiles(1) to always provide a From: address. Also, updated
+ its switches.
+- Fixed pick(1) to properly unfold multiple-line header fields by
+ removing newlines instead of replacing them with spaces [Bug #15215].
+- Removed the artificial limit of 1000 messages at a time for rmmproc.
+- Fixed decoding of header fields when they contain a character that
+ can't be converted.
+- post(8) -sasl now honours username in .netrc [Bug #23168]. whom(1),
+ send(1), inc(1), and msgchk(1) also benefit from this fix. And, nmh
+ now supports specification of any valid filename in place of
+ $HOME/.netrc.
+- Added quoting of local part of invalid address in message being
+ replied to [Bug #26780].
+- Fix segmentation faults for %(putlit) and %(zputlit) format escapes when
+ the "str" register was NULL.
+- Encode and decode text MIME types with canonical line breaks properly.
+- mhstore(1) now obeys its -noverbose switch.
+- Properly report the input filename when mhbuild encounters errors.
+- Set the content-transfer-encoding properly when attaching message/rfc822
+ content.
+
+---------------
+NOTABLE CHANGES
+---------------
+
+The biggest changes in this release are in the arena of MIME handling.
+Specifically relating to MIME composition and display. On the
+composition front, mhbuild(1) will now automatically be run by send(1)
+for all drafts. Specifically, mhbuild is now run with the new -auto
+flag, which will suppress the processing of mhbuild directives and cause
+mhbuild to silently exit if the draft is already MIME-formatted. When
+invoking mhbuild manually via the "mime" command at the WhatNow? prompt,
+mhbuild will behave as before and process mhbuild directives.
+
+In both cases (automatic and manual invocation) mhbuild will encode email
+headers according to RFC-2047 rules. Mhbuild also will use RFC 2231
+encoding rules for MIME parameters when appropriate. In addition, the
+attach system has been substantially reworked; the new header name is
+now "Attach" (to better align with other MUA behavior) and cannot be
+changed by the end-user. The existing "attach" command simply adds
+the filename(s) to the draft in new Attach: headers, and the actual
+file processing is done by mhbuild; this attachment processing will
+take place in either automatic or manual mode.
+
+On the display front, mhshow(1) will now automatically convert text
+into the user's native character set using iconv, if nmh was built
+with iconv support. Also, mhshow will now by default only display
+text content that was not marked as an attachment. By default all
+displayed content wll be run under one pager, as opposed to individual
+pagers for each part as was in the past. Non-displayed parts will be
+indicated using a marker string, which can be customized by a new
+mh-format(5) string.
+
+All nmh utilities now understand RFC 2231-encoded MIME parameters and
+will automatically convert the encoded parameters into the native
+character set, when appropriate (again, assuming nmh was built with
+iconv support).
+
+In other changes, sequence files are now locked using transactional
+locks: locks that are held across sequence file reading, modification,
+and writing. The locking algorithm used for spool files and nmh data
+files is now runtime configurable.
+
+For people that struggle with mh-format(5) files, a new utility for testing
+them has been developed: fmttest(1). It includes the ability to trace the
+execution of format instructions.
+
+For users that wish to use Unix utilities on their mail, a new utility
+to transform MIME messages to more easily-digestable format is now
+available: mhfixmsg(1). It supports a number of options to control
+the message transformation.
+
+For users of spost(8), the support for spost has been rolled into post(8)
+under a new sendmail/pipe MTS. A shell script emulating the old behavior
+of spost has been provided.
+
+As always, feedback is welcome.

+#
+# NEWS - Release notes for nmh 1.4
+#
+
+This releases contains numerous bugfixes and a number of new features.
+The new features include:
+
+- SASL security layers (encryption) are now supported for the SMTP MTA.
+- TLS is now supported for the SMTP MTA.
+- inc can now incorporate mail from Maildir drops.
+- 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 built-in ftp client) now supports IPv6.
+- 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':
+ http://www.mewburn.net/luke/src/new
+- nmh will no longer attempt to install a mhn.defaults file that causes
+ mhshow to open its own xterms.
+
+A large chunk of old code has been garbage collected. Specifically,
+support for APOP, RPOP, NNTP (including bboards) and MPOP is now gone.
+Also gone is support for prefixing a \01 in the "servers" entry in
+mts.conf to iterate over all servers on a named network.

+# NEWS - Release notes for nmh 1.3
+#
+
+It's been over two years since the 1.2 release; but the changes here are
+mostly minor; largely bugfixes.
+
+You should note that we have changed the default configuration to allow
+all supported forms of address masquerading. For more details please see
+the --enable-masquerade option to configure, and the mh-tailor and post
+man pages.
