   12 On this day in 1978 Kurt Shoens placed the following comment in
   13 def.h (now it is in nail.h):
   15   /*
   16    * Mail -- a mail program

   21 v14.9.10 is mostly a stability and bugfix release.
   22 It has seen a full test series including Coverity.com scans.
   23 It fixes bugs i have introduced (also a double free in IMAP cache
   24 that i introduced for v14.9.* series to address Coverity CID
   25 1376978..).
   27 In the end i am saying thanks to Gunnar Ritter for the IMAP
   28 module, and absolutely especially his really neat idea of an IMAP
   29 cache including offline work queue.  (IMAP will nonetheless
   30 temporarily go in v15, but these ideas will come back thereafter.)
   31 I have gray hairs now.

   35 Ralph Corderoy and Philipp Gesang.
   37 A special credit to Coverity.com again.  Because:
   38     tcc is 618496 bytes, pcc is 851968+24576 bytes,
   39     but gcc is 73355264 bytes and clang is even
   40     147406848 bytes, i wonder why the latter two never
   41     said a word that would have addressed the pretty
   42     obvious CID 1387053!
   43     [Use of initialized value, the author.]
   45 We welcome Stuart Henderson and Philipp Gesang in THANKS.
   47 NOTES, ChangeLog (packager-affine)
   48 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   50 - The balls are now build with umask 0022 not 0027.
   51   (William Yodlowsky, Stuart Henderson)
   53 - One actual development of this version was the addition of
   54   multiple choice VAL_ues, as documented in make.rc.
   55   For now we have VAL_IDNA (for OPT_IDNA)
   56     VAL_IDNA="idnkit idn2 idn"
   57   and VAL_RANDOM (by itself)
   58     VAL_RANDOM="arc4 ssl libgetrandom sysgetrandom urandom builtin"
   59   (Stuart Henderson)
   61   In brief:
   62     The value is interpreted as a whitespace separated list of
   63     strings, like "idn2 idn idnkit", case is ignored, order is
   64     important.
   65     The special strings "all" and "any" as well as the empty value
   66     are wildcard matches; if any entry in the list is a wildcard
   67     match, the rest of the list is ignored.
   69     The special string "error" will abort configuration once its
   70     list position is reached; this is only supported if
   71     documented, and not with an accompanying OPT_ (which then
   72     offers "require", as below).
   74   Since this VAL_RANDOM approach is so much better i have dropped
   75   OPT_SSL_RANDOM and OPT_NOEXTRANDOM that were recently
   76   introduced again.  They were c..p.
   78 - Support for idnkit 2.3 has been added.
   79   Support for idnkit 1 (especially as idnkitlite) has been fixed.
   81 - For the first time this codebase should be able to handle
   82   invalid MBOX mailboxes (produced by, e.g., dma(1)) gracefully.
   83   I hope i have found all places (sic) where code has to be fixed.
   84   E.g., "? copy * INVALID-MBOX" now works.
   85   (Smalltalk already knew objects which know what they are doing
   86   are for the better...  This is v15, then.)
   88 - P.S.: the two FreeBSD test failures are noted in INSTALL.
   90 ChangeLog
   91 ^^^^^^^^^
   93 - *asksend*#351 will now really allow recomposing.
   95 - `help'#198 now supports recursive `commandalias'#151es, and
   96   command self-recursion detection now works differently, it has
   97   been false for something like
   99       commandalias x q; commandalias q echo au
  101   since q became expanded to `quit'#233 (alias expansion equals
  102   new command word).  New behaviour: we allow equals once:
  104     commandalias q q; commandalias x q; x
  105   ->
  106     x -> q -> q -> quit
  108 - *editalong*#385 can have a value, say "set editalong=v" and it
  109   will startup $VISUAL#597 not $EDITOR#575.
  111 - Path separators are now normalized, thus all places, including
  112   MLE tab-expansion ("On terminal control and line editor"#17),
  113   can expand something like "///t*////t*".
  115 - -E#62 flag will not be obsoleted.
  116   -D#60 flag has been reintroduced (sets *disconnected*#622 right
  117   away, was not reinstantiated with the rest of the IMAP support.)

  164 v14.9.9 ("Marsh tit savours first spring sun, II") 2018-03-06
  165 -------------------------------------------------------------
  167 A bugfix release.
  168 I hope with this the fallout of the Christmas 2016 "address the
  169 Dr. Problem workshop" has been fully resolved and thus MIME for
  170 header address fields, even if iconv(3) is involved, been fully
  171 restored!  We have even more tests for this now.
  173 The release v14.9.8 was broken on big endian machines.
  174 I will remove the v14.9.8 balls from the server by the weekend.
  175 Sorry for the inconvenience!
  177 Credits, in order of commit appearance: Slavko, Matej Mužila,

  179 Predrag Punosevac.
  181 We welcome Slavko, Matej Mužila, Rich Felker and Simon McVittie in
  182 THANKS.
  184 NOTES, ChangeLog (packager-affine)
  185 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  187 - The v14.9.* series called *pipe-TYPE/SUBTYPE*#462 handlers in
  188   display or quote mode with CR (carriage-return) bytes stripped
  189   because of a missing output file comparison check, which broke
  190   binary formats etc.  (Slavko)
  192 - We now have native support for Libidn2.  (Matej Mužila)
  194 - uname(1) is now hookable by setting the shell variable uname
  195   when calling make ("uname=MY-UNAME make config" etc.).
  196   (Simon McVittie)
  198   We no longer bake the kernel version into the binary, and
  199   `version'#288 includes uname(2) output.
  200   (Simon McVittie, Paride Legovini)
  202 - We now support a fallback P(seudo)R(andomNumber)G(enerator)
  203   initialization even if getrandom(2)/getrandom(3) has been found
  204   by the configuration, just like we do for "/dev/urandom" usage.
  205   This does not affect systems with arc4random(3) or OpenSSL
  206   random usage.  (David Čepelík, Simon McVittie)
  208   A new OPT_SSL_RANDOM make.rc variable, by default initialized to
  209   the value of OPT_SSL.
  211 ChangeLog
  212 ^^^^^^^^^
  214 - `~@'#304 list-edit behaviour in -##85 batch mode was broken.
  216 - Character set names will now undergo generic normalization,
  217   including stripping of iconv(3) //SUFFIXes.

  253 A maintenance release which fixes bugs and brings in features.
  255 Credits, in order of commit appearance: Alexander Harm,
  256 Viktor SZÉPE, Paul Eggert, Joseph Bisch, Paride Legovini,
  257 and Peter J. Holzer.
  258 A special credit to the disappearing mutt(1) bug tracker.
  259 And to Gmane.org for creating gmane.mail.s-mailx.general!
  261 Thanks Paride Legovini for becoming maintainer of the Debian port.
  263 We welcome Joseph Bisch, Paride Legovini, and Peter J. Holzer in
  264 THANKS.
  266 NOTES, ChangeLog (packager-affine)
  267 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  269 - The USB stick loss reported for v14.9.6 was fake news, so to
  270   say, the stick exists and therefore the old key is not
  271   compromised.
  273 - We are back at Gmane.org!
  274     news.gmane.org/gmane.mail.s-mailx.general
  276 - `history'#199 has learned to be context-sensitive a bit, and
  277   has two new subcommands, `load' and `save'.
  279     This is in parts backward incompatible because it needs a new
  280     *history-file*#407 format; however, the old format can be loaded
  281     yet compose-mode commands will not appear in compose mode no
  282     more.  Iirc you can start with an old format then `save' to
  283     the new, then replace the "d" in the first column with "c" for
  284     compose-mode commands which should appear correctly.
  286 - Obsoletion warnings for variables now happen at `set'#255
  287   time instead of when used.  Running once via -v#82 may
  288   be beneficial.
  290 - The saturation modifier of `vexpr'#289 is henceforth a prefix,
  291   the suffix version is obsolete (but still supported for a while).
  293 - A network address that contains no domain-, but only a valid local
  294   user <name> in angle brackets will be automatically expanded to
  295   a valid address when *hostname*#412 is set to a non-empty value;
  296   setting it to the empty value instructs us that the used *mta*#441
  297   (including builtin SMTP) will perform the necessary expansion.
  298   (Viktor SZÉPE)
  300   Note that *hostname*#412 as well as *smtp-hostname*#522
  301   will now undergo IDNA expansion if IDNA is supported.
  303   And *from*#401 and *sender*#499 are now verified at `set'#255
  304   time, not when used.  (Viktor SZÉPE)
  306 - The commit message in [d503bd82] is wrong, apologies to
  307   Paride Legovini.  The test(1) operator "-n" appeared in Seventh
  308   Edition UNIX, not V8 as falsely claimed.
  310 ChangeLog
  311 ^^^^^^^^^
  313 - Our `addrcodec'#131 parser chokes on lesser constructs.
  315 - Presence of command-line MTA arguments without *expandargv*#391
  316   are now a hard error.  It was my fault that this was not the
  317   default from the very start.  (Viktor SZÉPE)
  319 - Seen on the mutt bug tracker, we also still have had problems
  320   with time settings that cross 32-bit boundaries.  As that is
  321   in parts induced by the C standard, now implement those parts on
  322   our own, and be super careful in general.  (Joseph Bisch)
  324 - The `~@'#304 command escape did not shell-unquote the user input
  325   again and was thus a bit broken; message attachments also work
  326   again.
  328 - Support custom headers from the command line via -C#58.
  329   And *customhdr*#378 is verified upon `set'#255 time.
  331 - The simple builtin HTML viewer now supports <blockquote>
  332   elements, which many web mailers, most notably gmail, use for
  333   citation.  (Peter J. Holzer)

  376 ------------------------------------------------------
  378 A bugfix release which fixes four serious and three other bugs.
  379 A few new features came in, too.
  381 Many thanks go to Ralph Corderoy who reported an issue that was
  382 caused by a terrible, terrible word reversal that i managed to
  383 produce in December 2016, and which caused the v14.9.x series to
  384 not MIME encode (non-address) content of address header fields!

  393 NOTES, ChangeLog (packager-affine)
  394 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  396 - After USB stick loss the authors OpenPGP key has been switched to
  398     pub   4096R/1883A0DD 2017-11-30 [expires: 2027-11-28]

  401     uid                  Steffen Nurpmeso <steffen@sdaoden.eu>
  403 - $TMPDIR#595 no longer honoured for root runs.  (Solar Designer)
  405 - *mime-encoding*#439 defaults to quoted-printable again.  (Cág)
  407 - We _can_ MIME encode even header fields which contain addresses.
  408   Thanks to Ralph Corderoy we now also _do_ so again!
  410 ChangeLog
  411 ^^^^^^^^^
  413 - ***#336 now uses *ifs*#414 when splitting.
  415 - Freezing *ttycharset*#561 via -S#77 also survives using or
  416   setting any of $LC_ALL#577, $LC_CTYPE#578 and $LANG#579 during
  417   program startup.
  419 - New `local'#115 command modifier to localize changes.
  420   Yet supported only for `set'#255, i.e., we have gained
  421   macro-local variables.
  423 - `vexpr'#289 now supports a BASE#number notation for integers,
  424   like 16#AFFE as an alternative to 0xAFFE.
  426   Hint: variable settings can most often use several bases, too,
  427   e.g., i have "set mime-counter-evidence=0b1111".
  429 - Very simple form of *quote-chars*#482 to adjust our knowledge of
  430   what actually is to be treated as a quote character.
  432 - *mime-counter-evidence*#438 deep inspection (bit four) has
  433   been improved for the sole cases of quoting or displaying
  434   a message.  So messages with less than 25% of control characters
  435   and such will now be displayed (made printable).  This is yet
  436   not configurable nor do we have a way to easily access a message
  437   with more than that.  (Doug McIlroy)

  474 -------------------------------------------------------
  476 A bugfix release which fixes two bugs which were cast in stone.
  477 A few compatibility improvements (AlpineLinux, Solaris).
  478 And minor features.
  480 Apologies to Jörg Schilling, a git bug i think it was who caused
  481 joining of changesets, loosing a credit, and it had been pushed to
  482 [master] before the problem was realized.
  484 Credits, in order of commit appearance: Jörg Schilling,
  485 Doug McIlroy, Random832, Nick Stoughton and Ivan Tham.
  487 We welcome Nick Stoughton and Ivan Tham in THANKS.
  489 NOTES, ChangeLog (packager-affine)
  490 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  492 - New OPT_USE_PKGSYS option can be disabled to not automatically
  493   pick known package system paths (pkg(7), OpenCSW, schily).
  494   (Jörg Schilling)
  496 ChangeLog
  497 ^^^^^^^^^
  499 - The software indeed _never_ dealt with iconv(3) output character
  500   set errors (as opposed to invalid input character set byte
  501   sequences etc.) for the main message body!
  502   And I have missed that when i tweaked our iconv layer a bit!
  504 - Fixed a race condition with sigsuspend(2) that i could only see
  505   on OpenBSD.  config.h offers n_SIGSUSPEND_NOT_WAITPID, by the
  506   way, which saves some systemcalls and did not run races, but
  507   noone adjusts this file.
  509 - Message list specifications gained two new colon modifiers, one
  510   can now "search :Ll" to find "Mailing lists"#10.
  511   The *headline*#404 format %T now also uses L and l rather than
  512   S and L accordingly.
  514   New `addrcodec'#131 subcommand `skinlist' acts like `skin'
  515   but stores in *!*#333 *^ERR*#335-EXIST if the address is
  516   one of the known "Mailing lists"#10.
  518 - `echo'#168 family now supports `vput'#118 and *!*#333 error
  519   storage, offering some kind of printf(1) experience, almost.

  542 v14.9.4 ("(5th anniversary) Marsh tit"), 2017-09-18
  543 ---------------------------------------------------
  545 This is an update feature release but which also ships a furious
  546 number of bug fixes, about six of which were pretty serious.  It
  547 also applies overall trimming, and improves configuration time
  548 compatibility on macOS.
  550 Thanks to Alexander Harm there is now a macOS Homebrew package.
  552 Credits, in order of commit appearance: Paul Vojta, Daniel Lublin,
  553 Alexander Harm, Norman Ramsey, Viktor Szépe, Rich Salz,
  554 David Čepelík, Ralph Corderoy, Stéphane Chazelas, Aharon Robbins,
  555 Ken Hornstein.
  557 We welcome Daniel Lublin, Alexander Harm, David Čepelík and
  558 Stéphane Chazelas in THANKS.
  560 NOTES, ChangeLog (packager-affine)
  561 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  563 - Out-of-tree builds have become possible via the new
  564   make-emerge.sh script:
  566   $ cd /tmp && mkdir build && cd build &&
  567     ~/src/nail.git/make-emerge.sh &&
  568     make tangerine DESTDIR=.ddir
  570   We now have a `citron' make target which is like `tangerine' but
  571   does not run the tests.
  573 - Configuration with OPT_AUTOCC honours $CC=cc. (Norman Ramsey)
  575 - SSL/TLS configuration has been revamped (again) in order to
  576   support new possibilities of OpenSSL (and LibreSSL) without
  577   ending up and introducing more and more variables.
  579   Instead we now have *ssl-config-pairs*#543, a comma-separated
  580   list of all options.  With e.g. OpenSSL 1.1.xx this will be
  581   directly passed through to SSL_CONF_cmd(), so there _anything_
  582   can be passed, otherwise we use a builtin parser to map.
  583   The new *ssl-features*#547 states what is supported.  E.g.:
  585     if [ "$ssl-features" =% +ctx-set-maxmin-proto ]
  586       wysh set ssl-config-pairs='\
  587           CipherList=TLSv1.2:!aNULL:!eNULL:@STRENGTH,\
  588           Curves=P-521:P-384:P-256,\
  589           MinProtocol=TLSv1.1'
  590     else
  591       wysh set ssl-config-pairs='\
  592           CipherList=TLSv1.2:!aNULL:!eNULL:@STRENGTH,\
  593           Curves=P-521:P-384:P-256,\
  594           Protocol=-ALL\,+TLSv1.1 \, +TLSv1.2'
  595     endif
  597   OpenSSL v1.1.xx also introduces an interesting and neat idea to
  598   centralize SSL/TLS configuration of (all) programs in a single
  599   file.  This can be driven via *ssl-config-file*#541 and the new
  600   *ssl-config-module*#542 variables, several entries per program
  601   are allowed, see *ssl-config-module*#542 for an example.
  603   New manual section "Encrypted network communication"#13.
  605 - Variables set or unset via -S#77 are now frozen until program
  606   startup is complete.
  608 ChangeLog
  609 ^^^^^^^^^
  611 - Historical behaviour of *askcc*#349 / *askbcc*#350 has been
  612   reintroduced.  (Norman Ramsey)
  614   A new *asksend*#351 variable will show a final header summary
  615   and allows reentering compose mode.  Set by default.
  617   POSIX mirrors *ask* onto *asksub*#353, so dropped" the former.
  619 - `~^'#306 no longer normalizes header names to titlecase.
  621 - We no longer generate charset=binary MIME parameters.
  622   This was introduced on 2013-01-02 and was i think owed to
  623   file(1)s -i output as i failed to find any other reference.
  624   (Normal Ramsey)
  626 - *mime-alternative-favour-rich*#437 now also works for handlers
  627   installed via *pipe-TYPE/SUBTYPE*#462. (Viktor Szépe)
  629 - v14.9.* series did not generate In-Reply-To: headers!
  631 - `alias'#132 now supports high-bit bytes and semicolon.
  632   Expect that at some later time the input must be valid according
  633   to the locale, though. (Norman Ramsey)
  635 - Combinations of *record*#486 could crash because of an
  636   unterminated variable function argument list. (Norman Ramsey)
  638 - New command `readall'#235 loads an entire file into a variable.
  640   *signature*#506 has been obsoleted.
  642 - `vexpr'#289 now supports negative arguments for the substring
  643   subcommand and adds trim, trim-front and trim-end subcommands.
  645 - `!'#122 can be used in send mode.
  647 - `~A'#307, `~a'#308, `~I'#317 and `~i'#318 will henceforth expand
  648   \t and \n only if *posix*#475 is set.
  649   Please use `set'#255 instead (with `wysh'#119, until v15).
  651 - New "The mime.types files"#35 type marker: @q ("quiet").

  707 ------------------------------------------------------------
  709 This is a bugfix release but which ships some improvements, too.
  710 It silently replaces both of v14.9.1 v14.9.2 from earlier this
  711 week, which were broken or not entirely fixed.
  713 Credits, in order of commit appearance: Felix Fontein, Paul Vojta,
  714 Ralph Corderoy, Christos Zoulas, Gavin Troy, Gaetan Bisson.
  715 Thanks, Coverity.com.
  717 We welcome Christos Zoulas in THANKS.

  720 the v14.9.0 announcement.
  721 And to Gaetan Bisson for not giving credit for [14fbce97]!
  723 NOTES, ChangeLog (packager-affine)
  724 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  726 - fakeroot support was blindly taken from Debian and broken.
  727   (Gavin Troy, Gaetan Bisson)
  729 - Base64 output was broken for cases which involved iconv(3).
  730   The data is not lost, you can read it with S-nail v14.9.0 and
  731   above, and save it somewhere.  I know of no other base64 decoder
  732   which reads those things correctly, though.  We now have tests.
  733   Along this i fixed an iconv(3) error which likely caused
  734   stateful decoding (like, e.g., for ISO-2022-JP) to fail because
  735   of an unnecessary reset of the iconv(3) state machine.
  736   Thanks to Gaetan Bisson for mentioning this issue!
  738 ChangeLog
  739 ^^^^^^^^^
  741 - In compose mode the MLE allows empty lines again.
  743 - We no longer require a writable $HOME#576.  Due to false code
  744   flow (but but but: with correct comment) a non-writable $HOME
  745   entry in /etc/password (i.e., from getpwuid(3)) would lead to
  746   a crash.  (Felix Fontain; Ralph Corderoy)
  748 - Two faulty string operations slipped into the IMAP code,
  749   resulting in a crash and a "is-same-host" test that would fail
  750   for IMAPS connections like `save'#252 or `copy'#154 because of an
  751   implicit IMAP protocol for the target of those operations (thus
  752   IMAP != IMAPS).  (Paul Vojta)
  754 - The MLE tab-expansion will now automatically append a "/" if
  755   there is only one possible expansion and that is a directory,
  756   saving the user one <TAB>.  (Christos Zoulas)
  758   The shell expression parser had a bug regarding understood
  759   metacharacters (;|&), which in turn could cause an infinite loop
  760   in the MLE tab-expansion for, e.g., "move &9 +<TAB>", because
  761   the "&" would never have been stepped over.
  763 - New `~I'#317 command escape is like `~i'#318 but does not append
  764   a newline.
  766 - `localopts'#204 gained an optional second argument.
  767   It is now possible to specify that any macro `call'#140ed
  768   will have localopts enabled, and it is possible to fixate the
  769   setting so that it cannot be reverted.
  771 - *@*#339 should now act completely compatible to the sh(1)ell,
  772   thus obsoleting my hysteric warnings in the v14.9.0 announcement.
  774 - The `Lreply'#205, `reply'#240, `Reply'#239 series as well as
  775   `mail'#207 now manage the error status *!*#333.
  776   I.e., there are now errors like *^ERR*#335-DESTADDRREQ,
  777   ^ERR-NODATA, ^ERR-PERM and similar.  It is not perfect yet,
  778   because $DEAD#574 may have been written (with *save*#494) or not,
  779   for example.
  781   `Lreply' and `reply' have been rewritten rather completely
  782   indeed.  They join Reply-To: and Mail-Followup-To: dependent on
  783   the context (i.e., *reply-to-honour*#492, *followup-to-honour*#398,
  784   see "Mailing lists"#10 for the picture), and if they did, use
  785   this list as the receivers exclusively.  It now honours
  786   *recipients-in-cc*#485 even for such addressees.  (And now i wonder
  787   whether i should have credited Paul Vojta for that.)
  789   Also `Lreply' would have crashed for mails with Reply-To: but
  790   without *reply-to-honour*#492 set.  We now have a test.
  792   Note *replyto* is obsoleted in favour of *reply-to*#491.

  810 v14.9.0 ("Long-tailed tit"), 2017-07-16
  811 ---------------------------------------
  813 This is a major feature release which took about ~22 months (24
  814 less two) of development to complete, and which imposed massive
  815 changes under the hood, but also quite a lot of user visible
  816 changes, including some **backward incompatibilities**.
  817 As usual, "s-nail -d" will show obsoletion warnings.
  819 We gain noticeable improvements regarding scriptability and its
  820 reliability, but also for interactive use cases, especially
  821 notable to users is our completely new M(ailx)L(ine)E(ditor) that
  822 supports rather real tabulator expansion and program-mode-context-
  823 sensitive key bindings.
  825 We now support macros with arguments, which can be `shift'ed,
  826 a `return' status can be used, and a `vexpr' multiplexer offers
  827 some arithmetic and string operations.  `commandalias'es are
  828 recursive, further command modifier prefixes, like `ignerr', give
  829 a hand that we otherwise could not offer.  In compose-mode the new
  830 `~^' command escape allows some message and attachment access, and
  831 can be used, e.g., to implement things like custom headers, and
  832 has been especially designed for scripted access via the new
  833 *on-compose-splice* and *on-compose-splice-shell* hooks.
  835 S-nail will move (more or less) backward-incompatibly to sh(1)ell
  836 compatible argument quoting (documented in "COMMANDS"), and an
  837 increasing number of commands do support this already: new ones
  838 exclusively, some old ones have either been switched (like
  839 `localopts'), others -- noticeably `set' -- can be switched to the
  840 new syntax with a `wysh' command modifier prefix.  E.g.:
  842   ? define __xv {
  843     # Be careful to choose sh(1)ell-style on _entire_ line!
  844      localopts yes; wysh set verbose; ignerr eval "${@}"; return $?
  845     }
  846   ? commandalias call echo boo-boo
  847   ? commandalias xv call __xv
  848   ? xv list
  849   ? commandalias xv '\'call __xv
  850   ? xv list
  852 Calling the latter `xv' for `list' will give more detailed command
  853 information, including which kind of argument is used.
  855 I have not managed to implement the three features i have started
  856 this development cycle for, these are thus subject to further
  857 development, just like wysh for message-list argument commands to
  858 support, e.g., negation, wysh for `if' and consorts, the --
  859 terminator to finally overcome the ridiculous requirement to quote
  860 entire shell commands filenames for commands like `pipe.
  861 And and and.

  890 NOTES, ChangeLog (packager-affine)
  891 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  893 * This release brings some backward incompatibilities, outlined
  894   in the following.  Most users will not be affected, and we have
  895   added a lot of compatibility cruft, but that will vanish in v15.
  896   "$ s-nail -v"!
  898 * The configuration and build system has changed.
  899   Packagers have received updated package files.
  901   o Anything which was WANT_xy before is now OPT_xy, and
  902     compiled-in paths and values, like PREFIX or PAGER, have
  903     gained a VAL_ prefix (thus VAL_PREFIX and VAL_PAGER).
  905     This is _not_ true for non-persistent or environmental values,
  906     e.g., DESTDIR, CC, etc., and also not for the overwritable
  907     program variables during configuration, e.g., $awk.
  910     MAILSPOOL -> VAL_MAIL.
  911     And NAIL -> VAL_MAILX, though this is still a lie.
  913   o The make system now needs config..build..install or
  914     all..install or tangerine (config..build..test..install).
  915     Some constants which some experts may want to fine-tune have
  916     been moved to config.h.  Usual adjustments+doc via make.rc.
  918   o The `build' phase can be parallelized by setting the $MAKEJOBS
  919     environment variable, e.g., "make MAKEJOBS=-j4 build".
  920     Note this variable is not tracked in the configuration.
  921     (Gaetan Bisson)
  923   o Unless DESTDIR is set an uninstallation script will be
  924     installed along with the rest (see INSTALL file for more).
  926   o Set the new OPT_CROSS_BUILD to avoid feature runtime tests,
  927     only compile- and link-availability will be tested.  (Juan RP)
  929   o VERBOSE is implemented straight, but must be given at
  930     configuration time in order to become honoured.
  931     (William Yodlowsky)
  935   o The LD_LIBRARY_PATH etc. building processes will skip any path
  936     which contains the string "fakeroot".  (Hilko Bengen)
  938   o We honour a set $SOURCE_DATE_EPOCH#593 environment variable to
  939     an extend that allows reproducible tests, which is why the
  940     repository gained a [test-out] branch with some expected plain
  941     text outputs.  (reproducible-builds.org; Colin Watson)
  943     The new *log-prefix*#425 variable aids in improving the
  944     reproducibility of error messages.
  946   o These are upward compatible changes.
  948 * "make OPENSSL_API_COMPAT=0x10100000 all" should work.
  950 * Internal and environment variables are now explicitly _defined_
  951   and _tracked_ after variable handling has been rewritten
  952   completely.  Notes:
  954   o This means that, e.g., "$ password=NOT_SECRET s-nail" will
  955     **NOT** work no more, since *password*#460 is an internal
  956     variable!
  958   o But if you do, e.g., "? set TMPDIR=~/tmp", then this will
  959     also be reflected in the program environment (it is an
  960     environment variable) and thus affect child processes.
  962   o Therefore we no longer have `setenv' and `unsetenv'.
  964   o To integrate any other environment variable transparently
  965     into our variable management, the new command `environ'#176
  966     needs to be used, e.g., "? environ set NEWVAR=value" or
  967     "? environ link EXISTINGVAR".
  969 - -H#66 and -L#69 have been decoupled:
  970    it used to be -e#63 -L#69 instead!
  972 - *NAIL_{HEAD,TAIL}* have been obsoleted in favour of
  973   *message-inject-head*#433 and *message-inject-tail*#434.
  975   *NAIL_HIST{FILE,SIZE}* have been obsoleted in favour of
  976   *history-file*#407 and *history-size*#410.
  978   *NAIL_EXTRA_RC* has been obsoleted in favour of
  979   *mailx-extra-rc*#428.
  981   *batch-exit-on-error* has been obsoleted by *errexit*#388, which
  982   works just like the POSIX sh(1)ell "set -e" construct; the
  983   `ignerr'#114 command modifier (`-' for command escapes in compose
  984   mode, and see below) can be used to ignore command errors even
  985   then.  (This will remain even if we at some later time will
  986   support at least some of the sh(1) constructs which "swallow"
  987   failures with set -e.)
  989   *bsdannounce* is obsolete, the feature is integrated in
  990   *header*#403 as this is much more useful.  (This is however also
  991   dependent upon the also new but well-known $POSIXLY_CORRECT#591
  992   <> *posix*#475, but that is just how it is; these affect more
  993   behaviour, and increasing.)
  995 - Colour support has been changed backward in- and upward (from
  996   user interface side) compatibly, see the manual section
  997   "Coloured display"#18.
  999   + New commands: `colour'#149 and `uncolour'#150.
 1000     You can define context-sensitive, terminal-capability-
 1001     sensitive settings, e.g.:
 1003       if terminal && [ "$features" =% +colour ]
 1004         colour iso  view-header ft=bold,fg=magenta,bg=cyan
 1005         colour 256  view-header ft=bold,fg=208,bg=230 subject,from
 1006         colour mono view-header ft=bold
 1007         colour mono view-header ft=bold,ft=reverse subject,from
 1008       endif
 1010   + The variable *colour-pager*#374 defines whether colour and font
 1011     attribute sequences should be generated when viewing something
 1012     in $PAGER#589.
 1014   + Set the variable *colour-disable*#373 to turn colour off
 1015     without affecting established settings.
 1017   + It is deduced via termcap(5) (see below) whether the terminal
 1018     supports colors, e.g., "$ s-nail -Stermcap=Co#256".
 1019     This is also true if we don't have termcap support.
 1021   + Support for 256-colour terminals. (Gavin Troy)
 1023 - `source'#267 series support shell pipes if the last character
 1024    of the "filename" ends with a vertical bar |, e.g.,
 1026       ? source 'gpg -qd ~/.s-nailrc-private.gpg |'
 1028 - Shell pipes are also supported as targets for `move'#217,
 1029   `copy'#154 etc., yet unfortunately not with via a sh(1)ell token
 1030   parser, so that the target still has to be a single argument.
 1032       ? copy . '| cat; echo huhu'
 1034 - Support for custom headers via the new `~^'#306 compose-mode
 1035   command escape and in addition, or alternatively, with the
 1036   internal variable *customhdr*#378, which also can be covered by
 1037   `localopts'#204.  (Sergey Matveev)
 1039   + Support of $ORGANIZATION has been dropped.
 1041   + Command escape `~e'#312 supports _any_ header.
 1043   + Command escape `~^'#306 supports _any_ header.
 1045 - New -:#53 command line option can be used to more easily select
 1046   which startup files should be loaded, e.g., -:/ loads none.
 1047   (Robert Elz)
 1049 - `account'#129s and *folder-hook*#395s now have `localopts'#204
 1050    enabled by default.
 1052 - A first simple form of compose-mode hooks has been implemented:
 1053   *on-compose-enter*#453, *on-compose-leave*#454 and
 1054   *on-compose-cleanup*#452 can be set to macros which get invoked
 1055   at appropriate times.
 1056   For the `resend'#244 series there is *on-resend-enter*#458 and
 1057   *on-resend-cleanup*#457: this is very likely to change once
 1058   true message access is possible even in this mode.
 1060   An even more powerful mechanism is available via the also new
 1061   *on-compose-splice*#455 and *on-compose-splice-shell*#456 hooks.
 1062   These are executed in child processes and communicate with the
 1063   parent via their standard input and output, and therefore can
 1064   do anything and act as if they were the user.
 1066   `localopts'#204 are enabled and cannot be disabled (and extend
 1067   until the message is sent).
 1068   (Jens Schleusener, Rudolf Sykora)
 1070     ? set on-compose-splice=ocs
 1071     ? define ocs {
 1072       read ver
 1073       echo Splice protocol version is $ver
 1074       echo '~^header list'
 1075       read hl; vput vexpr es substring "${hl}" 0 1
 1076       if [ "$es" != 2 ]
 1077         echoerr 'Failed to read header list, bailing out'
 1078         echo '~x'
 1079       elif [ "$hl" @i!% ' cc' ]
 1080         echo '~^header insert cc Diet is your <mirr.or>'
 1081         read es; vput vexpr es substr "${es}" 0 1
 1082         if [ "$es" != 2 ]
 1083           echoerr 'Failed to insert Cc:, bailing out'; echo '~x'
 1084         end
 1085       end
 1086     }
 1088 - "The .netrc file"#37
 1090   + gained support for comments.
 1091     (Walter Alejandro Iglesias, Ralph Corderoy)
 1093   + `netrc'#220 now has a "load" subcommand.
 1095   + the new *netrc-pipe*#447 obsoletes OPT_AGENT and
 1096     *agent-shell-lookup*, and can be used to load an encrypted
 1097     .netrc file, e.g.:
 1099       ? set netrc-lookup netrc-pipe='gpg -qd ~/.netrc.gpg'
 1101     I.e., this is in usual .netrc syntax and thus possibly much
 1102     nicer than saying "? source 'gpg -qd ~/.credentials.gpg |'".
 1104 - termcap(5) / terminfo(5) support has been changed backward in-
 1105   and upward (from user interface side) compatibly, please read
 1106   "On terminal control and line editor"#17.
 1108   + OPT_TERMCAP is by default enabled.
 1109     The new, by default enabled, configuration option
 1110     OPT_TERMCAP_VIA_TERMINFO can be used to (try to) use
 1111     terminfo(5) instead.
 1113   + The variable *termcap*#556 can be used to freely define or
 1114     override terminal capabilities, and *termcap-disable*#558 will
 1115     disable interaction with the chosen library, leaving only
 1116     *termcap* in charge.
 1118     To use the so-called ca-mode on supporting terminals,
 1119     effectively turning S-nail into a fullscreen application,
 1120     *termcap-ca-mode*#557 must be set.
 1122   + The built-in line editor has been rather completely rewritten
 1123     to be the Mailx-Line-Editor (OPT_MLE, default yes), and
 1124     supports wide glyphs (if possible), infinite line lengths
 1125     (2 GB) and more.  Tabulator expansion is no longer an option
 1126     (but needs fnmatch(3)).
 1128   + Optionally (OPT_KEY_BINDINGS, default yes) it has become
 1129     possible to freely define key bindings for the MLE via the new
 1130     `bind'#138 and `unbind'#139 commands.  These key bindings can
 1131     make use of termcap(5) and/or terminfo(5) names.  The MLE will
 1132     install a set of default bindings (unless there is a set
 1133     *line-editor-no-defaults*#424), more so with OPT_TERMCAP,
 1134     i.e., try "? bind*".
 1136     Sufficient support provided, one can now, e.g., type "p " and
 1137     then collect the message numbers to type, scrolling forward
 1138     and backward via key-bindings, without loosing the line
 1139     content, then commit the final line.
 1141   + OPT_EDITLINE and OPT_READLINE support have been dropped.
 1142     The new MLE should not miss anything.  Does it?
 1143     Tip: in an UTF-8 locale try "? !touch /tmp/hall{,öchen}" and
 1144     then autocomplete that: once, then ^Q, and again.
 1146 - `source'#267 can be used in `call'#140ed macros.
 1147   What sounds so innocent replaced an entire machinery and got rid
 1148   of a brilliant idea of Kurt Shoens from the 70s, but which never
 1149   worked with Nail/Heirloom extensions, namely macros, and in the
 1150   right order.
 1151   Accompanying this -X#83 can (dig multiline arguments and can) be
 1152   used to define macros and run them etc.  Should work:
 1154     $ s-nail -X'define x {' -Xversion -Xx -X'}' -X'call x'
 1155     $ s-nail -X'source \' -X'"echo version|"' -Xx
 1157   Macros can be `undefine'#159d from within themselves, and re-
 1158   `define'#158d.  It is still not possible to define macros
 1159   from within macros, and/or have inner macros, not to talk
 1160   about local scoping or anything more sophisticated such.
 1162 - -u#80 / $LOGNAME#582 ($USER) handling has been redefined,
 1163   and "-u USER" is now exactly the same as "-f %USER", and
 1164   $LOGNAME (and $USER) is actively set to the active user.  (Afan)
 1166   $LOGNAME#582 is POSIX standardized and henceforth used and
 1167   preferred over $USER, which came from BSD.  (Todd C. Miller)
 1169 - In the future (at least non-message-list) argument handling will
 1170   be changed backward-incompatibly to be sh(1)ell compatible (and
 1171   thus POSIX standardized), see "Shell-style argument quoting"#24.
 1172   New commands use it already today (`bind'#138, `colour'#149,
 1173   `headerpick'#195), some others (most importantly, `set'#255) can
 1174   be forced to do so via the new `wysh'#119 command prefix, as in:
 1176     ? wysh set message-inject-tail=$'\n--steffen'
 1177     ? bind base $'\cA,\x61' 'echo control-A and small a'
 1179 - We now actively manage *umask*#563: 0077 by default, but an
 1180   empty string will use the setting that is active upon startup.
 1181   Just like changes to (known) environment variables, this setting
 1182   will also be inherited by any child process.
 1183   (Walter Alejandro Iglesias)
 1185 - Anything SENDMAIL / *sendmail*-ish has been renamed to *mta*#441,
 1186   *mta-arguments*#442, *mta-no-default-arguments*#443 and
 1187   *mta-argv0*#445.
 1189   The reason is that in v15 we won't even have *smtp*: it is just
 1190   another form of MTA, and thus obsolete by itself.
 1191   Note that *mta-arguments* is now parsed via the shell-token
 1192   parser, so the following ends up exactly as desired.
 1194     ? set mta-arguments='-t -X "/tmp/my log"'
 1196   For now we support a hack that understands a file:// URL in
 1197   *mta*, too, but that is also the default if there is no protocol.
 1198   E.g.: "? set mta=smtp://a:b@xy.z"
 1200 - The "spamd" *spam-interface*#525 is obsolete.  I haven't tested
 1201   it since my main machine died, it is error prone since it assumes
 1202   internals of the spamassassin wire protocol, and there never was
 1203   a speed improvement over "spamc".  (However it could react upon
 1204   the "is-spam" state of a message, which "spamc" doesn't allow.)
 1206 - The new *inbox*#418 variable will henceforth be looked up when
 1207   searching for a primary system mailbox (as in "? File %"),
 1208   followed by the usual $MAIL#583 and compile-time defined local
 1209   mailspool search.  (Stephen Isard, Jürgen Daubert)
 1211 - The semantic of -a#55 and `~@'#304 have been changed, and both
 1212   commands now use the same syntax:
 1214     -a file[=input-charset[#output-charset]]
 1216 - New "failinvaddr" keyword for *expandaddr*#390.
 1218 - We finally "can" the so-called (by myself) "Dr. Problem" (a bit):
 1219   (Dr. Werner Fink)
 1221     $ </dev/null s-nail -d:/ -sTrödler 'Dr. D. Iet <z@a.k>' 2>&1 |\
 1222       grep To:
 1223     s-nail: >>> To: "Dr. D. Iet" <z@a.k>
 1225   This can be done via the new `addrcodec'#131, too, note this
 1226   supports multiple modes (and the `vput'#118 command modifier):
 1228     $ echo 'addrcodec e Dr. Diet <to@fu.soj> Curd' | s-nail -#:/
 1229     "Dr. Diet Curd" <to@fu.soj>
 1231 - All commands with the string "codec" in their name use different
 1232   argument quoting, namely none at all, please read
 1233   "Raw data arguments for codec commands"#25.
 1234   This means that `urlcodec'#284 (and `imapcodec'#621) has
 1235   slightly changed semantics.
 1236   And, while here: there is a new `shcodec'#257, too.
 1238 - We gained "Command modifiers"#21: `\'#113 (avoid expansion of
 1239   `commandalias'#151es), `vput'#118 (store result in variable),
 1240   `ignerr'#114  (ignore an error of the following command, even
 1241   if the new *errexit*#388 is set), `wysh'#119 (use shell-style
 1242   arguments).
 1244     $ echo 'vput cwd resvar;echo $resvar' | s-nail -#:/
 1245     /home/steffen/src/nail.git
 1247   And the usual sh(1) stuff: `return'#250, `shift'#261, `eval'#178,
 1248   plus a `xcall'#293 stack-avoidance optimization (to be used in
 1249   place of a `call'#140 which would be the last called command).
 1250   And an "expr(1) like thing", yet simple, `vexpr'#289.
 1252     $ echo 'vexpr + 1 2' | s-nail -#:/
 1253     00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000011
 1254     03 | 0x3 | 3
 1255     $ echo 'vput vexpr resvar + 1 2;echo $resvar' | s-nail -#:/
 1256     3
 1258   We actually start walking (*?*#332, *^*#334).
 1260     ? vput vexpr res regex 'bananarama' 'Bana(.+)' '\$1\$0'
 1261     ? echo $?/$^ERRNAME :$res:
 1262     1/NODATA ::
 1263     ? vput vexpr res iregex 'bananarama' '(.+)rama' '\$1\$0'
 1264     ? echo $?/$^ERRNAME :$res:
 1265     0/NONE :bananabananarama:
 1267   The command `vpospar'#290 can be used to manage the stack of
 1268   positional parameters, i.e., much like "set --".
 1269   It also offers the possibility to save and restore the stack to
 1270   and from variables.  Etc.
 1272   Btw., to contact the maintainer (make.rc variables
 1275     ? echo $contact-web; eval mail $contact-mail
 1277 - `if'#201 no longer performs automatic number conversion, we
 1278   use the explicit -lt, -gt etc. syntax of the sh(1).
 1279   Note: `if' will change to be almost identical to sh(1) if(1),
 1280   so please ensure proper test bracketing, even if it is less
 1281   convenient.
 1283   Moreover, the default string comparison mode has changed to
 1284   case-sensitive, just like in the shell.  This is because in the
 1285   future this crux with trigger characters will vanish and `if'
 1286   etc. will simply slurp in already expanded shell tokens, it will
 1287   act like the shell in that respect.  We have modifiers, though,
 1288   yet only "@i" for case-insensitivity, also for regex matches:
 1290     LC_ALL=C
 1291     i=`LC_ALL=C.utf8 s-nail -:/ -# -X '
 1292        \define cset_test {
 1293           \if [ "${ttycharset}" @i=% utf ]
 1294              \echo $LC_ALL

 1307    [ $? -eq 0 ] && UTF8_LOCALE=$i
 1309   Please note the `eval' in 'eval xcall cset_test "${@}".  This is
 1310   a difference of S-nail/mailx and the sh(1)ell that will remain,
 1311   as documented in "COMMANDS"#20: whereas the shell implements
 1312   a language and performs standardized expansions on the line
 1313   until finally the command is called, S-nail will decide the type
 1314   of command line parsing dependent on the seen command, and will
 1315   then perform a single expansion.  Therefore "${@}" will expand
 1316   to multiple arguments if $# is greater 0, but it will expand to
 1317   the empty string otherwise, which is not furtherly expanded away
 1318   since it is meaningless like it is in the shell: therefore $#
 1319   will be 1 (the empty string) not 0.
 1321 - Using an explicit proto:// prefix should get you the desired
 1322   thing apart of *newfolders*#448, e.g.:
 1324     ? File maildir:///tmp/x.mdir
 1325     ? copy * file:///tmp/x.mbox
 1327 - New variable *record-files*#487 can be set to extend the meaning
 1328   of *record*#486.  *record-resent*#488 was there already.
 1330 - New variable *ifs*#414 acts a bit like the sh(1)ell's $IFS for,
 1331   e.g., the new `read'#234 command.
 1333   There is a `readctl'#236 command which can be used to manage
 1334   the active channel used by `read'#234.
 1336 - The `~' alias for `call'#140 is gone.
 1338 - `mimetype'#209 only allows specification of a single type per
 1339   call, on the other hand no need to quote that.
 1341 - `mimeview'#213 must now be used explicitly to look at any
 1342   non-text MIME part, for normal display etc. purposes we only
 1343   support "copiousoutput"#608 MIME handlers.
 1345 - New *socks-proxy*#524 can be used to proxy all network traffic
 1346   over a SOCKS5 proxy.  (Gaetan Bisson)
 1348 ChangeLog
 1349 ^^^^^^^^^
 1351 - The manual has seen another major overhaul, all the variables
 1352   are now documented in a single, sorted list, and many
 1353   clarifications should have been added.  I hope it has become
 1354   a better read.
 1355   (Predrag Punosevac, Michael Convey, Hariskar, Rudolf Sykora,
 1356   Respiranto, Thomas Dickey, Donald Mugnai)
 1358 - To support RFC 1524 a.k.a. .mailcap files (see below) many
 1359   "trigger"-characters have been added for *pipe-TYPE/SUBTYPE*#462,
 1360   which may (rarely) affect existing values.
 1361   The .mailcap support itself is not yet implemented.
 1363 - *mime-counter-evidence*#438 gained bit 4 (perform proper in-depth
 1364   content inspection as necessary; set to 0xE for all bits).
 1365   (Aharon Robbins)
 1367 - Maildir paths are now created recursively as necessary.
 1368   (Justin Ellingwood)
 1370 - -M#70 and -m#71 options have been added to enforce a special
 1371   send mode that will flag standard input / the given file with
 1372   the specified / detected MIME 'Content-Type:'.  This can be used
 1373   to directly send, e.g., HTML log output.
 1374   (Viktor Szépe, Ralph Corderoy)
 1376 - Disallow symlinks on writable files.  Note this requires
 1377   O_NOFOLLOW support for the operating-system-call open(2), but
 1378   which has been standardized a long time ago.
 1379   (Matthew Dillon)
 1381 - `retain'#249, `ignore'#202 etc. now differentiate in between
 1382   From (the From: header) and From_ (the MBOX ident).
 1384   In fact we now have a new `headerpick'#195 command which
 1385   is a multiplexer for all retain and ignore lists used, call it
 1386   without arguments to see the current setting(s).
 1387   In v15 only `headerpick' and the standard-imposed wrappers
 1388   `retain' and `ignore' will remain, all other wrappers will
 1389   vanish.  Regular expressions can now be used if available:
 1391     ? headerpick
 1392       headerpick type retain blahblahblah cc date from \
 1393         mail-followup-to message-id openpgp reply-to subject to \
 1394         user-agent
 1395       #headerpick type ignore currently covers no fields
 1396       #headerpick save retain currently covers no fields
 1397       headerpick save ignore '^Original-.*$' '^X-.*$' '^DKIM.*$'
 1398       headerpick forward retain cc date from list-id \
 1399         mail-followup-to openpgp reply-to subject to
 1400       #headerpick forward ignore currently covers no fields
 1402 - `top'#276 has been rewritten completely, `Top'#275 is new.
 1403   It uses a built-in set of retain/ignore headers, but it is
 1404   possible to register a custom set via `headerpick'#195.
 1405   Also, *toplines*#559 has been extended a bit and the new
 1406   *topsqueeze*#560 variable may pimp your `top' experience.
 1408     ? headerpick top retain add subject
 1409     ? top
 1410     [-- Message  1 -- 87 lines, 4791 bytes --]:

 1413     I wrote:
 1414         3.22. bounce_delivered
 1416 - `features' has been dropped, `version'#288 extended.
 1418 - The *prompt*#477 handling has changed: we lost the capability to
 1419   expand \?, \@ and \$, instead new "private" variables *?*#332,
 1420   *account*#343, *mailbox-resolved*#427 and
 1421   *mailbox-display*#426 have been introduced, and the prompt
 1422   is completely shell expanded (thus twice with `wysh' or in v15),
 1423   as if dollar-single-quote quoted.  We do support the reverse-
 1424   solidus escaped bracket notation for embedding characters which
 1425   should not be counted when calculating the width of the prompt.
 1426   The `colour'#149 command has a slot for the prompt colour.
 1427   We gained *prompt2*#478 as a second level prompt.
 1429     ? var prompt
 1430     wysh set \
 1431       prompt='?\${?}!\${!}[\${account}#\${mailbox-display}]? '
 1433 - The filename "-" can be used as a receiver, e.g.,
 1435     $ echo Hey,\ you | s-nail -:/ -Sexpandaddr -sUB -
 1437 - The -s#78 command line option, the `~s'#325 command escape
 1438   as well as the corresponding slots of `~^'#306 will actively
 1439   strip [\r\n] from their value (Debian #419840).
 1441 - New `read'#234 and `echoerr'#169 commands, mostly for
 1442   *on-compose-splice*#455.
 1443   But also `echon'#170 and `echoerrn'#171, which do not write
 1444   a trailing newline.
 1446 - New variable *r-option-implicit*#484 may be helpful to those
 1447   who regulary need the functionality of the -r#76 command
 1448   line option.  (Felipe Gasper, Martin Neitzel)
 1450 - By using new "pseudo-URLs" one can automatize the use of S/MIME
 1451   keys / (certificates / intermediate include certificates) with
 1452   passwords.  E.g., to drive bob@exam.ple, set
 1453   *smime-sign-cert-bob@exam.ple* to the private key / certificate
 1454   pair as usual, the password lookup will then be performed for
 1455   bob@exam.ple.smime-cert-key, bob@exam.ple.smime-cert-cert and
 1456   bob@exam.ple.smime-include-certs.
 1457   Like this the password can be stored in an encrypted .netrc file
 1458   when *netrc-lookup*#446 and *netrc-pipe*#447 are set, or it may
 1459   be stored in an encrypted resource file that has been loaded via
 1460   `source'#267 as a simple *password*#460 variable.
 1462   Note that the prompting that happens as a last resort of
 1463   password lookup will still interfere with a possibly running
 1464   $PAGER#589 instance, dependent on the setting of *crt*#377, of
 1465   course.  Proper job control handling and recognizing that we are
 1466   running $PAGER when doing that prompt is a TODO for v15.  Sorry.
 1468 - Some commands, like `set'#255, `help'#198, `list'#203,
 1469   `mlist'#211 etc., now react upon the setting of *verbose*#566
 1470   and(/or) *debug*#381.
 1472 - `write'#292 uses iconv(3) as appropriate.
 1474 - *mbox-rfc4155*#430 has first been dropped, and was then
 1475   reintroduced with different semantics.  Because, it can be
 1476   helpful if a messed up MBOX is read, in which case we henceforth
 1477   will warn you and point you to this:
 1479     ? define mboxfix {
 1480       \localopts yes; \wysh set mbox-rfc4155;\
 1481         \wysh File "${1}"; \eval copy * "${2}"
 1482     }
 1483     ? call mboxfix /tmp/bad.mbox /tmp/good.mbox
 1485   P.S.  Here you see how weird the current thing still is, in v15:
 1487     ? define mboxfix {
 1488       localopts yes; set mbox-rfc4155; File "${1}"; copy * -- "${2}"
 1489     }
 1491   And also in v15 we will not apply (proper) so-called MBOXO
 1492   quoting, but instead (simply MIME) re-encode mail messages.
 1494 - `call_if'#141 is new and, different to "? ignerr call", silent
 1495   and not messing with the return status.
 1497 - The new *smime-ca-flags*#510 and *ssl-ca-flags*#537 can be used
 1498   to fine-tune X509_STORE_set_flags(3) a.k.a the X509 CA
 1499   certificate verification.
 1501     ? set ssl-ca-flags=partial-chain
 1502     ? wysh set smime-ca-flags="${ssl-ca-flags}"
 1504   Also, *ssl-curves*#546 for TLSv1.3.
 1506 - Socket connections use TLS S(erver)N(ame)I(ndication) as
 1507   appropriate (RFC 7817).
 1509 - `alternates'#134 checks arguments and supports `vput'#118.
 1510   It by default no longer replaces but appends alternates, unless
 1511   *posix*#475 mode is active.  There is a new `unalternates'#135
 1512   command to remove alternates.
 1514 - A new `charsetalias'#144 command.  (Pietro Cerutti, mutt#3925)
 1516 - New commands `filetype'#182 and `unfiletype'#183: in the future
 1517   we will no longer know any builtin filetypes, in fact we already
 1518   simulate .gz etc. via the new mechanism as necessary:
 1520     ? filetype \
 1521        bz2 'bzip2 -dc' 'bzip2 -zc' \
 1522        gpg 'gpg -d' 'gpg -e' \
 1523        gz 'gzip -dc' 'gzip -c' \
 1524        xz 'xz -dc' 'xz -zc' \
 1525        zst 'zstd -dc' 'zstd -19 -zc' \
 1526        zst.pgp 'gpg -d | zstd -dc' 'zstd -19 -zc | gpg -e'
 1528 - `~<'#301 now offers a "- [HERE-delimiter]" mode for pasting etc.
 1529   (Ralph Corderoy)
 1531 - `exit'#179 and `quit'#233 take an optional exit status.
 1532   (That is not fixated yet, though.)
 1534 - We have a useful -h / --help output.  (Doug McIlroy)
 1536 - *encoding* obsoleted in favour of new *mime-encoding*#439, which
 1537   now defaults to base64.
 1539 - *allnet*#345 now works (broken since nail 10.00, 2002-09-29).
