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. + +-- +The nmh team +nmh-workers@nongnu.org + +---------------------------------------------------------------------------- + +# # NEWS - Release notes for nmh 1.6 #
