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 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.
-- 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.
-- All TLS connections now perform certificate validation (including hostname
- matching) by default; can be disabled on a per-application basis.
-- 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.
-- 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
+- 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 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.
+- 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
-------------------
-- 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.
+- 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
---------
-- 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)
+- 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.
