   12 O tempora!  O mores!
   13 Three fixes for thoughtless and also in other ways superficial
   14 code changes i have done.
   15 Apologises to all, but especially to Mr. Bell.

   22 ChangeLog
   23 ^^^^^^^^^
   24 
   25 - After "echo foo | s-nail $USER" we no longer leave the terminal
   26   in a different state than it should be.  Terminal initialization
   27   was not rethought from scratch after we focused on the MLE
   28   editor only and after we have implemented our own termcap/info
   29   layer .. now done, and -A account switch and -X commands now run
   30   properly covered already, too.  (Olav Mørkrid)
   31 
   32 - I had implemented a thoughtless use of close_range() aka
   33   closefrom() -- this was totally broken (mysteriously not covered
   34   by the tests, have to look, will fix for the future, too).  We
   35   can never do this, and if it is only for `readctl'#254.

   43 ad7750d4 Mess! OpenSSL changed DEFINE_STACK_OF() 3.0 crap once again!!  Sorry!
   44 0d71e7ec main(): call mx_termcap_destroy() at times (Olav Mørkrid)
   45 aae70019 Do the latter right
   46 75970d68 Thank you, Olav!  (More fixes for the fix of the fix, that is)
   47 77b7d20c Hoooorray! One more fix needed for Olav Mørkrid!
   48 fac2d327 FIX! Remove close_range brain damange (Russell Bell, Johannes

   51 v14.9.21 ("Tit escapes with a peanut"), 2021-01-21
   52 --------------------------------------------------
   53 
   54 I apologise for the inconvenience of yet another bugfix release.
   55 It fixes a possible SMTP buffer overflow triggerable by
   56 a malicious server as reported by Olav Mørkrid, and a socket code
   57 memory access error that can be seen when using IMAP on at least
   58 Solaris, which was reported by Jörg Schilling.
   59 
   60 Yasuhiro Kimura helped to unconfuse problems that i attributed to
   61 BSD make, but which were indeed shell errors, most notably mksh.
   62 Excuses are due to the forgiving and friendly Simon Gerraty (BSD
   63 make) and Paul Smith (GNU make).
   64 (In the end test job reaper code has been rewritten completely.)

   74 NOTES, ChangeLog (packager-affine)
   75 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   76 
   77 - The test now can skip individual tests included in $SKIPTEST,
   78   for example "# make test SKIPTEST='eval vexpr'.
   79 
   80 - New option VAL_ERRORS_LIMIT (by default enbaled), and new
   81   variable *errors-limit*#415 to configure error ring size.
   82 
   83 - We become even more portable to SysV/Solaris.  (Jörg Schilling)
   84 
   85 ChangeLog
   86 ^^^^^^^^^
   87 
   88 - Without termcap/terminfo support the outermost column was always
   89   made accessible (since "not not" defining "am" in *termcap* is
   90   not possible, bug since v14.9.12), on the other hand the "ch"
   91   builtin implementation never reached out to this last column
   92   (since ever).
   93 
   94 - Manual: after rewrite and review i think the manual section
   95   "Character sets"#15 is of acceptable quality.  (Jörg Schilling)

  116 NOTES, ChangeLog (packager-affine)
  117 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  118 
  119 + FreeBSD, DragonFlyBSD, (NetBSD): there are bugs in BSD make and
  120   FreeBSD-derived sh(1)ells regarding sh(1) monitor mode that is
  121   now used in mx-test.sh ("make test").
  122   Please pass in JOBMON=n on make(1) command line, or use
  123   a different shell (and make).
  124 
  125   (You could also pass in a different JOBWAIT= now.)
  126 
  127 + Binaries are now installed 0755 not 0555.  (Jürgen Daubert)
  128 
  129 + On SunOS/Solaris we now use the normal $CC detection algorithm.
  130   (No longer forcefully overwrite, prefer open source compilers.)
  131 
  132 - TLS connections can now be proxied via *socks-proxy*#569.
  133 
  134 - `echo'#182 no longer performs "Filename transformations"#27.
  135   Introduced in BSD Mail in 1988, but bad.
  136   Just use `vexpr'#303 file-expand.
  137 
  138 - `local'#127 now works like `localopts'#218 when used
  139   with `set'#269 and `unset'#270.
  140   This is true for built-in variables only, of course, using
  141   `local' for those was forbidden in the past, i think.
  142   Note that `localopts' will be obsoleted in v14.10, we will only
  143   use modifiers in the future.
  144 
  145 ChangeLog
  146 ^^^^^^^^^
  147 
  148 - EXTERNAL authentication over IMAP and POP3 was fixed.
  149 
  150 - *tls-fingerprint*#596 is now tested case-insensitively.
  151 
  152 - *quote*#520 gained an "allbodies" keyword.
  153 
  154 - "The Mailcap files"#37 gained "x-mailx-last-resort" and
  155   "x-mailx-ignore" flags.  (Latter: Russell Bell)
  156 
  157 - `history'#213 "delete" can now delete multiple entries per
  158   invocation.

  187 
  188 NOTES, ChangeLog (packager-affine)
  189 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  190 
  191 - Warning: we _will_ have v15-compat=yes as a default in v14.10!
  192 
  193 - Fix for `~f'#328, `~m'#334, `~Q'#336, `~U'#342 and `~u'#343:
  194   no longer include all MIME parts (bug since at least v14.9.16).
  195 
  196 - Fix for handling of "The Mailcap files"#37:
  197   a single copiousoutput/x-mailx-tmpfile-fill|nametemplate
  198   combination was falsely handled, mostly affecting binary file
  199   formats (which got broken by applied character set conversion).
  200 
  201 - Fix for automatic S/MIME encrypted key / certificate password
  202   lookup: used $LOGNAME@[no hostname].smime-cert-key as
  203   a fallback, instead of using the value of *from*#432.
  204   (Noctambule)
  205 
  206 - `~R'#338 and `~r'#339, as well as all prompts which expect
  207   file names and did not yet do so, expect shell-quoted names.
  208   (See "Shell-style argument quoting"#24.)
  209 
  210 ChangeLog
  211 ^^^^^^^^^
  212 
  213 - `~Q'#336 now acts as if *quote*#520 is set.
  214   Does not really make sense otherwise.
  215 
  216 - New environment variable $SOCKS5_PROXY#635 is tight together
  217   with *socks-proxy*#569: setting the one affects the other.
  218   This $SOCKS5_PROXY is introduced by FreeBSD to affect all
  219   programs which are capable to proxy via SOCKS5 (it seems).

  224 v14.9.17 ("To bind, or not to bind.."), 2020-02-02
  225 --------------------------------------------------
  226 
  227 A shadowed key bindings report on bash-bugs@ made me aware that
  228 our `bind' code has never seen a real review, and not only were we
  229 incapable too, but the code was a piece of shit, when i looked at
  230 it.  So please find here a bugfix release to smoothly end v14.9.
  231

  239 
  240 And now for something completely different.
  241 
  242 NOTES, ChangeLog (packager-affine)
  243 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  244 
  245 - "make test" now works when run by root or on read-only
  246   file-systems.  (Johannes Schöpfer)
  247 
  248 - Our `bind'#150 now supports overall key-sequence timeouts,
  249   as opposed to inter-byte timeouts.  For this i have obsoleted
  250   *bind-timeout* in favour of *bind-inter-byte-timeout*#380
  251   and *bind-inter-key-timeout*#381 (not set by default).
  252 
  253   The bind tree code had two bugs, for one the "shortcut"
  254   key-bindings would all have been created in the "base" context,
  255   not where they really belong ("default" and "compose").
  256   And due to false list relinking shadowed key bindings did not
  257   work.  (Koichi Murase)
  258 
  259   When used with 3x*verbose*#? (aka -v#86) the bind tree
  260   is now dumped when it has been build (once used first, and after
  261   modifications.  Putting all this together, a resource file
  262 
  263     cat >/tmp/t.sh <<'__EOT'
  264     MAILX=s-nail
  265     cat >/tmp/t.rc <<'_EOT'
  266     set line-editor-no-defaults
  267     bind base $'\n' mle-commit
  268     bind base $'\c?' mle-del-bwd
  269     bind base $'\cT' echo one
  270     bind base $'\cT',$'\cT' echo two
  271     bind base abc echo 0
  272     bind base ab,c echo 1
  273     bind base abc,d echo 2
  274     bind base ac,d echo 3
  275     bind base a,b,c echo 4
  276     bind base a,b,c,d echo 5
  277     bind base a,b,cc,d echo 6
  278     set quiet noheader
  279     set bind-inter-key-timeout=2500
  280     set bind-inter-byte-timeout=250
  281     bind base a,b,c,d # now works, too!
  282     _EOT
  283     MAILRC=/tmp/t.rc $MAILX -R:u -Y 'set verbose=3'
  284     rm -f /tmp/t.sh /tmp/t.rc
  285     __EOT
  286     sh /tmp/t.sh
  287 
  288   will now do the expected.
  289 
  290 - `Reply'#257: no longer honours *recipients-in-cc*#528
  291 
  292 ChangeLog
  293 ^^^^^^^^^
  294 
  295 - Manual: after review i think the following sections are of
  296   acceptable quality: "On terminal control and line editor"#18,
  297   "Coloured display"#19.
  298 
  299 - *verbose*#607 is no longer a boolean but can be assigned
  300   a numeric value.  But "set verbose verbose verbose"
  301   also still works.
  302 
  303 - New variable *reply-to-swap-in*#536 tries to work around
  304   the DKIM/DMARC "HUMAN via LIST <LIST@ADDRESS>" ugliness
  305   when `reply'#259ing (or `Reply'#257ing) to such a message.
  306   It tries to move the HUMAN into responsibility.

  312 
  313 At the end of the v14.9 series we finally deliver the RFC 1524
  314 mailcap support, as well as other improvements, and new features.
  315 Many bugfixes and tests arrive.
  316 A whole bunch of things are backward-incompatible, but i would
  317 assume that most use cases are not at all affected.

  330 NOTES, ChangeLog (packager-affine)
  331 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  332 
  333 - Renamed *expandaddr*#417 namehostex to nametoaddr.  (Better.)
  334 
  335 - *tls-features*#595 string now starts and ends with comma.
  336   (Just like *features*#420 does.)
  337 
  338 - -L#72 longname --header-search renamed to --search.
  339 
  340 - Config option OPT_FORCED_STACKPROT=xy now
  341   OPT_AUTOCC_STACKPROT=y, and now auto-enabled for OPT_AUTOCC=y
  342   (even though i hate that, protectors in shipout code..).
  343 
  344 - `account'#141 return value now matters, and can thus be used to
  345   abort account switching.
  346 
  347 - -:#56 has new "x" mode, which executes the directives of the
  348   compiled-in resource file.  (The template content is now
  349   compiled in too, so the real file does not need to be loaded.)
  350   (Brian Evans)
  351 
  352 - Quote etc. injections (*quote-inject-head*#525) now always
  353   happen (if set), regardless of *quote*#520.
  354 
  355 - We now truly honour POSIX command abbreviations (order).
  356   As part of that i finally implemented a simple command lookup
  357   speedup, these are now almost alphabetical (unless abbreviations
  358   prevent it).
  359 
  360 - Added *mta-bcc-ok*#482.  Bummer.  It seems exim and courier
  361   do not remove Bcc: headers as required by standards unless
  362   invoked with a special command line argument.  So we now
  363   do not pass Bcc: headers to file-based MTAs unless this
  364   variable is set explicitly.  (Kevin McCarthy).
  365 
  366 - "COMMAND ESCAPES"#29 now have a $ command modifier, which
  367   causes a shell-style `eval'#192uation before the command
  368   escape is executed.
  369 
  370   And so `~<'#315, `~R'#338 and `~r'#339 no longer expand $VAR
  371   expressions by themselves.
  372 
  373   And so -a#58, `~@'#318, and "attachment insert" of `~^'#320
  374   and `digmsg'#175 only perform ~/-style expansions.
  375 
  376 - `~^'#320: use shell-style argument expansion.
  377   We handled `~^' and `digmsg' differently, but furthermore
  378   turned the shell-parsed data of the latter into whitespace
  379   separated data, which made it impossible to, for example,
  380   use attachments with whitespace in their names.
  381 
  382   This increases the interaction protocol version number of
  383   *on-compose-splice*#492 from "0 0 1" to "0 0 2"!
  384   Because, we do also quote the output, since using `read'
  385   (or read(1)) causes *ifs*#445 ($IFS) normalization.
  386   All that could be done would be (for ourselves):
  387 
  388       define x {
  389         set ifs=
  390         read vany
  391         unset ifs
  392         vpospar set $vany
  393         # And now assign the desired real fields
  394         set real-var1=$1 real-var2=$2  ...
  395       }
  396 
  397   Sick!  So instead introduce a `readsh'#252 command which works
  398   like `read'#251 but splits fields at shell token boundaries,
  399   for example from within *on-compose-splice*#492:
  400 
  401     echo '~^h s subject'; read stat name; readsh sub; read i
  402 
  403   There would be better examples.  (Ralph Keller)
  404 
  405 - `~F'#327, `~f'#328, `~M'#333, `~m'#334, `~U'#342 and `~u'#343 now
  406   honour *forward-inject-head*#430 and *forward-inject-tail*#431.
  407 
  408 - New option OPT_MAILCAP, by default enabled.
  409   Disable at runtime via *mailcap-disable*#460, all documented
  410   in "The Mailcap files"#37.
  411 
  412 - OpenBSD: really auto-find number of processors in test script.
  413   Work around fflush(3) not adapting POSIX behaviour.
  414 
  415 - Manual: after review i think the following sections are of
  416   acceptable quality: "Encrypted network communication"#14,
  417   "A starter"#6, "On URL syntax and credential lookup"#13,
  418   "The Mailcap files"#37, and
  419   "But, how about XOAUTH2 / OAUTHBEARER?"#46.
  420 
  421   The latter is actually (Stuart Henderson, Benjamin A. Wong),
  422   and now provides a copy+paste example of how to keep a
  423   OAUTHBEARER token up-to-date with S-nail (with some care).
  424   Yes, it is terrible.
  425 
  426 - Default .rc file: keeps Sender: by default (Ken Hornstein),
  427   sets *followup-to-honour*#427 and *reply-to-honour*#535,
  428   and gives more *history-gabby*#439ness.
  429 
  430 ChangeLog
  431 ^^^^^^^^^
  432 
  433 - Add `Lfollowup'#219.  (Russell Bell)
  434 
  435 - `?'#139: prefix \ (quoted!) to command to avoid
  436   `commandalias'#163  matching:
  437 
  438   ? ? S
  439   S -> spamspam: Teach the spam detector that <msglist> is spam
  440   ? ? \\S
  441   S (Save): Like `save', but derive filename from first sender
  442 
  443 - `history'#213 has new "delete NUMBER" subcommand.
  444 
  445 - Add *forward-add-cc*#428 and *quote-add-cc*#521 to Cc: the
  446   originator of a forwarded or quoted message, respectively.
  447   (Goesta Smekal)
  448 
  449 - *history-gabby*#439 now has a value to allow for more.
  450   This changes second argument of *on-history-addition*#494
  451   from boolean to context string.
  452 
  453 - New command `mtaaliases'#236.  We no longer automatically
  454   update the *mta-aliases*#477 cache.  (Maybe much later we will
  455   have a path_monitor or something, until then, not.)
  456 
  457   And `netrc'#237 "load" is now indeed "clear" + "load".
  458 
  459   `netrc' also gained a "lookup" subcommand.  (Ralph Corderoy)
  460 
  461 - *headline*#435 %L format will announce possibility that
  462   a message could be a list.
  463 
  464 - `chdir'#158, `rename'#256 and `remove'#255 use shell-style
  465   argument quoting.
  466 
  467 - `tls'#289 gained "certchain" and "certificate" subcommands.
  468 
  469 - `folder'#201 can open RFC 5322 messages via eml:// protocol,
  470   as in "folder eml:///tmp/msg.eml".  Yet primitive and only
  471   read-only.  (Viktor Szépe)
  472 
  473 - `vexpr'#303 gained "date-utc", "date-stamp-utc" and "epoch"
  474   subcommands.  (Benjamin A. Wong)
  475 
  476 - *on-main-loop-tick*#495 now also happens for commands passed
  477   via -Y#88.

  481 v14.9.15 ("Tit family in the trees"), 2019-08-18
  482 ------------------------------------------------
  483 
  484 Plugging a bug regarding copying data out of invalid MBOX mail
  485 databases which is present in all BSD Mails and in Unix V10 mail,
  486 and bringing in some tweaks, this update hopefully really marks
  487 the end of the v14.9.* series.
  488 
  489 After more than four and a half years i again have a VM testbed,
  490 with an increasing number of VM combinations.  (Yet still too few,
  491 but nonetheless, a dramatical improvement.)  This includes
  492 a GSS-API testbed, with an ArchLinux server and Linux and FreeBSD
  493 clients (do not ask why no additional FreeBSD server, i want to
  494 use binary packages).  This brought GSSAPI tweaks.

  499 
  500 Very special thanks go to Tarqi Kazan and Ivan Vučica, who tested
  501 GSS-API in the past until it worked (again), testing against my
  502 blind flight patches!  Thank you very much, guys!

  504 We welcome Chet Ramey, Jilles Tjoelker and Steve Izma in THANKS.
  505 
  506 NOTES, ChangeLog (packager-affine)
  507 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  508 
  509 - *features*#420 and *tls-features*#595 are now prefixed with
  510   a comma ",", not with the number sign "#" (which could
  511   increasingly `eval'#192uate to a comment).
  512 
  513 - We now support parallelized tests.  It takes a numeric job
  514   number out of $MAKEFLAGS, or tries to fetch the number of
  515   processors otherwise (really!).  To go singleprocessor
  516   "$ make testnj" has to be called explicitly.
  517   With or without, we will terminate tests which take too long.
  518 
  519   This is truly tremendous, on the unstable9s machine of the
  520   OpenCSW.org cluster for example we now need 24 seconds instead
  521   of by far more than 300.  What a release!
  522 
  523   With help of (Chet Ramey, Robert Elz, Jilles Tjoelker and
  524   Steve Izma)
  525 
  526 - EXTERNAL authentication is truly a mess.  It has been fixed for
  527   POP3, where it was broken on our side.  But it seems the
  528   internet does not like that, or cannot (pass user credentials
  529   from a certificate gracefully to the authenticator).
  530   Anyway.  I have introduced EXTERNANON in addition for all of
  531   IMAP, POP3 and SMTP.  This could now result in a usable
  532   combination, regardless of what server(s) are contacted.
  533 
  534 - The hook *on-account-cleanup*#488 will now be called even
  535   upon program exit (i.e., implicitly leaving the account).
  536 
  537 ChangeLog
  538 ^^^^^^^^^
  539 
  540 - New *followup-to-add-cc*#426 will place the user in the Cc:
  541   list if it will place her in the Mail-Followup-To:.
  542 
  543 - New hook *on-program-exit*#496.
  544 
  545 - *pop3-auth*#510=gssapi is now supported.
  546   For IMAP, SASL-IR will be used for GSSAPI if possible (saving
  547   a packet round-trip).
  548 
  549 - *expandaddr*#417 has the new keyword "namehostex".
  550   If set, plain name addressees, like "To: steffen", will be
  551   expanded to NAME@HOSTNAME (where the latter could be
  552   *hostname*#443) if NAME is a valid user on the current host.

  557 v14.9.14 ("Great tit passed moult"), 2019-07-27
  558 -----------------------------------------------
  559 
  560 This is an unwanted and unplanned but unfortunately necessary
  561 bugfix release.  I hope it marks the end of the v14.9.* series.
  562 
  563 I presume you would be surprised if it would not also bring some
  564 features, this time mostly support of MTA-style aliases as
  565 inquired by Jean-Marc Pigeon, some authentication work (XOAUTH2/
  566 OAUTHBEARER support), and as usual development to the last minute.
  567 
  568 It fixes IMAP GSSAPI authentication, thanks to Ivan Vučica for
  569 reporting and testing this issue (Debian #930691; still have no
  570 testbed, but will soon!), and imap-delim, which i broke in July
  571 2017, thanks to Ralph Keller for repetitive reporting.
  572 
  573 For OpenBSD and SunOS 5.9 this release fixes long standing (must
  574 be) race conditions regarding child processes and their I/O setup.
  575 
  576   Never seen before, but my new box (i stepped a decade of
  577   hardware improvements, finally) rather regulary has shown them
  578   when running the test suite.  (On the OpenCSW cluster my speed
  579   varies, but i had a very good day and seen them there once.)
  580 
  581   This (finally) caused the complete rewrite of the child process
  582   (and termios) handling that i (had to) mention in communication
  583   with Gavin Troy already back in, i do not know -- 2013?  (Still
  584   not event loop based, but near getting good feelings there.)
  585 
  586   Funnily the problem (child descriptors were closed by the parent
  587   before the fork(2)ed childs had the opportunity to dup(2)licate
  588   their file descriptors) reminded me of a message of the german
  589   computer magazine c't, maybe around 2001/2002, when OpenBSD
  590   improved their fork(2) performance in a day or two after having
  591   appeared declassified in a comparison with other OSes.
  592   (Of course it was nothing but our own fault to not synchronize on
  593   the child, but blindly assuming that a fork(2) child gets the
  594   opportunity to run immediately.)
  595 
  596   Dear Predrag: would it now be possible for you to upgrade from
  597   v14.8.12?  I really would like to know!

  612 NOTES, ChangeLog (packager-affine)
  613 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  614 
  615 - The (very backward) Debian mawk is now supported directly.
  616   (Martin Lucina, Viktor Szépe)
  617 
  618 - GCC (8.3.0) -Os inlining bug (wmt) is worked around.
  619   And GNU awk 5 warnings have been fixed (before CRUX).
  620 
  621 - "|PIPE RECEIVER" errors seen on SunOS 5.9 and OpenBSD have first
  622   been fixed, and then caused a major rewrite of the child and
  623   termios handling for a rather "real" fix.
  624 
  625   The latter has the side effect that *pipe-TYPE/SUBTYPE*#502
  626   handlers will now have their standard output go to /dev/null.
  627 
  628 - IMAP GSSAPI authentication should work again.  (Ivan Vučica)
  629 
  630 - -C#61 testable can be used more than two times.
  631 
  632 - The "grappa" mode of mk/make-release.sh can now be used
  633   "everywhere".  See INSTALL on interest.  (It now gracefully
  634   fails if s-nail is not installed: we need that for hashing.)
  635 
  636 - New option OPT_MTA, by default enabled.
  637   Set *mta-aliases*#477 to a valid path in aliases(5) syntax,
  638   and we will expand them.  All Postfix directives but :include:
  639   are supported.  Only clear text files are supported, no DBs.
  640   (Jean-Marc Pigeon)
  641 
  642 - `~^'#320 will now verify *expandaddr*#417 right away in
  643   "~^ head ins to|cc|bcc", as is already done for `~t'#341,
  644   `~c'#324 and `~b'#323.
  645 
  646 - OPT_AGENT and OPT_SPAM_SPAMD are gone; they were obsoleted on
  647   2017-07-16, and it is not expected to become noticed.
  648 
  649 - *sendwait*#544 is now initially set, and it gained an optional
  650   value, a comma-separated list of case-insensitive strings naming
  651   specific subsystems for which synchronousness shall be ensured
  652   (only).  Possible values are "mta" for *mta*#476 delivery,
  653   and "pcc" for command-pipe receivers.
  654 
  655   P.S.: you can get a list of all initial values plus via
  656 
  657     $ s-nail -:/ -v -Xset -Xx
  658 
  659 - Colours may now happen even in quickrun mode (-e#66,
  660   -H#69, -L#72)!  I thought it is ok nonetheless, because
  661   we i think always documented to enwrap `colour'#161 setting
  662   in an according `if'#215, as in
  663 
  664     \if terminal && [ "$features" =% +colour ]
  665       \colo iso view-header fg=red
  666     \end
  667 
  668 - OPT_SOCKETS has been renamed to OPT_NET.
  669 
  670 - -Y#88 is now well defined under all conditions, with tests:
  671 
  672     The commands will be evaluated successively in the given
  673     order, and as if given on the program's standard input --
  674     before interactive prompting begins in interactive mode,
  675     after standard input has been consumed otherwise.
  676 
  677 - XOAUTH2 / OAUTHBEARER (OAuth 2.0 bearer token, RFC 6750)
  678   autentication is now supported for all protocols.
  679   New FAQ entry "But, how about XOAUTH2 / OAUTHBEARER?"#46
  680   For driving the necessary external update tool a new
  681   *on-main-loop-tick*#495 hook has been introduced.
  682   (I am thinking about adding support for an optional built-in
  683   token refresh.)
  684 
  685 - Support for the EXTERNAL authentication method has been
  686   introduced.  This is UNTESTED, though.  (I am still in the
  687   process of re-setting up my VM test environment.)
  688   We do not verify presence of a client certificate etc., but only
  689   that a TLS secured channel is active, when using this method.
  690   (We now *verbose*#607 log the used TLS version and cipher, too.)
  691 
  692 - *imap-delim*#669 works again as advertised!  This was broken in
  693   [1b9897a9] ((BWDIC!) Fix *imap-delim* behaviour.., 2017-07-01),
  694   and i think i was pretty much irritated by then.  Sorry!!
  695   While here, take *imap-delim* into account for `imapcodec'#665.
  696   (Ralph Keller).
  697 
  698 ChangeLog
  699 ^^^^^^^^^
  700 
  701 - Manual section "HISTORY"#52 improved a bit.  (Thomas Haigh)
  702 
  703 - New variable *line-editor-cpl-word-breaks*#454 (yet a bit
  704   restricted).
  705 
  706 - MLE: add mle-raise-{int,quit,tstp} functions.  Ie., raising
  707   those signals via ^C and ^Z is no longer hard-wired (in the
  708   MLE), but can be reassigned.  (Nicholas Marriott)
  709 
  710 - The makefiles no longer contain any awk code, that all has been
  711   separated into files under mk/.  (Alexander Harm)
  712 
  713 - We now have "test" *mta*#476, which dumps to standard output
  714   or optionally to a file, and honours *mbox-fcc-and-pcc*#463:
  715 
  716      $ echo text | s-nail -:/ -Smta=test -s ubject user@exam.ple
  717      $ </dev/null s-nail -:/ -Smta=test://./xy -s ub user@exam.ple
  718 
  719 - -##90 now acts as if variables were set via -S#80, rather than
  720   as via `set'#269, meaning that they are "frozen" for a while.
  721 
  722 - We have a new `colour'#161 mapping, "mle-error".
  723   It applies to error note in *prompt*#517, as well as to any
  724   other error logged to the terminal.  The latter is temporary
  725   until we gain a more fine grained logging facility, which then--
  726   likely--introduces an entire mapping family.
  727 
  728   Btw., for messages not explicitly generated (by, eg.,
  729   `echoerr'#183), we now also avoid writing adjacent duplicates,
  730   but rather do a syslog-like thing.  That error generator has
  731   been rewritten a bit, now more expensive, but looks right.
  732   (Martin Neitzel, Paul Vojta)
  733 
  734 - The value of $COLUMNS#615 seen in child processes is now the
  735   real one, rather than the one we use (not necessarily identical,
  736   dependent on termcap/terminfo/terminal support).
  737 
  738 - There are now three -v#86 / *verbose*#607 levels, not two.
  739 
  740 - The HTML filter knows more HTML 4.0 entities.  (Russell Bell)

  744 v14.9.13 ("Blue tit's spiral marriage swoop"), 2019-03-08
  745 ---------------------------------------------------------
  746 
  747 Not so much happened as i was busy with other things in the second
  748 half of 2018, and could not find a grip: at the source level some
  749 efforts to turn this to mailx have taken place, including early
  750 work on a code abstraction that will be shared with my (g)roff
  751 clone: it was tiring to come back to old ideas that i have already
  752 implemented multiple times and in different languages.  To mention
  753 it for the curious.
  754 
  755 So: this is a bugfix release, in fact it fixes a tremendous amount
  756 thereof, [master] was ahead by 62 commits from [v14.9.11] (not all
  757 bugs though, hrmhrm), but also with, well, a few new features, and
  758 of course, development to the last minute. ^_^
  759 
  760   v14.9.13 replaces v14.9.12 from yesterday which would pick up an
  761   ISO C 2011 statement that is impracticable, thanks to Johannes
  762   Schöpfer and Jürgen Daubert for reporting this (i should test
  763   without OPT_AUTOCC more often.)  I have also fixed -T to match
  764   NEWS (manual and code did the opposite).
  765   v14.9.12 balls will be removed from the server.

  774 Very special thanks go to Jean-Marc Pigeon of OSUKISS Linux, who
  775 provided me access to a VZGOT container on the most "beefy"
  776 machine i have ever had access to!  It is ever so astonishing to
  777 have work done in 90 seconds on this supercomputer which requires
  778 an hour or more here.  Thank you, Jean-Marc.
  779 
  780 And thanks to Kimura-san not only my web server became accessible
  781 via TLSv1.3 (out-of-line), but we also have landed on FreeBSD!
  782 Kimura-san is the one who installed a sympathic cron job that

  790 NOTES, ChangeLog (packager-affine)
  791 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  792 
  793 - Packagers could follow stable/* via git(1) and the "grappa" mode
  794   of the release script (see README); perl(1) is required to be
  795   totally en par with an official release.  (Paride Legovini)
  796 
  797     $ git checkout stable/stable
  798     $ sh mk/make-release.sh grappa mybranch
  799     ...
  800     Program version is [.], packager release addition shall be: xy
  801     Is s-nail <v[.]-xy> correct? [y/n] y
  802     Switched to branch 'mybranch'
  803     $ git commit -S -n -m 'My release [.]-xy'
  804 
  805 - $MAKEJOBS vanished, just use -j or whatever your make(1) supports.
  806   Luckily the tested make(1)s can be persuaded to dig each others
  807   .WAIT / .WAIT: / .NOTPARALLEL: targets.. and do the right thing.
  808 
  809 - $OBJDIR support added, i use it for building / testing on tmpfs.
  810   It works in conjunction with make-emerge.sh, too, thus
  811   out-of-tree out-of-tree is possible (more or less; see INSTALL).
  812     $ make tangerine OBJDIR=/tmp/x/y/z
  813 
  814 - Option VAL_PRIVSEP_USER has been renamed to VAL_PS_DOTLOCK_USER
  815   (to reflect the new "deep tree" directory layout).
  816 
  817 - Option OPT_QUOTE_FOLD has been renamed to OPT_FILTER_QUOTE_FOLD
  818   (to reflect later code changes upwards compatibly).
  819 
  820 - New options OPT_CMD_VEXPR and OPT_CMD_CSOP, by default enabled.
  821   To include the commands `vexpr'#303 and the new `csop'#167,
  822   which now provides the byte string functions of the former.
  823   (Still available through `vexpr' until v15.)
  824   (I hope to be able to later provide a `usop' or `unisop' or so.)
  825 
  826 - *v15-compat*#606 can now have a value: if it is set, the
  827   `wysh'#131 command modifier which chooses shell quoting rules
  828   for some commands is implicit.
  829 
  830 - We have some (more) backward incompatible changes, though it is
  831   likely most users will not recognize the differences.
  832 
  833   o *headline*#435 format %T is obsolete, %L fits better.
  834 
  835   o `csop'#167 `hash' and `hash32' subcommands (formerly from
  836     `vexpr'#303) use a slightly changed hash algorithm.
  837     (Which results in an improved distribution for tested sets of
  838     words in power-of-two spaced dictionary.)
  839     These are affected by the change in the second next item, too.
  840 
  841   o Changed to use shell quoting rules for arguments:
  842 
  843     + `mimetype'#225 and `unmimetype'#226.
  844       This is affected by the change in the next item, too.
  845 
  846     + `shortcut'#273 and `unshortcut'#274.
  847 
  848     + `mlist'#228 and `unmlist'#229 as well as `mlsubscribe'#230
  849       and `unmlsubscribe'#231.
  850 
  851     + `alias'#144, too.
  852 
  853   o Changed (with legacy compat) the "@[i]" modifier prefix to
  854     a question-mark ?[case|..] suffix, as is known from URLs.
  855     We head towards direction URL syntax, now here too.
  856 
  857     + `if'#215 and `elif'#187.
  858       E.g., 'wysh if "abc" ==?case "ABC"' is true, as well as is
  859       'wysh if 0xFFFFFFFFFFFFFFFF -eq?saturated 36#1Y2P0IJ32E8E7'.
  860       "==?" and "-eq?" would have been sufficient, here.
  861       (No unsigned mode (yet) for `if'#215.)
  862 
  863       Yes, `if'#215 and `elif'#187 now support `wysh'#131, and
  864       see already expanded arguments, then.  No more "triggers".
  865       This finally makes it possible to write things like
  866         ? wysh if X;A;wysh elif Y;B;else;C;end
  867       Note 'else;C' not 'else C'.
  868 
  869       New operators: '-n "$VAR"' and '-z "$VAR"' work like in the
  870       shell, '-N varname' and '-Z varname' do not test the
  871       expansion but the existence of variables instead.
  872       Two argument forms require `wysh'#131.
  873 
  874     + `mimetype'#225 markers have changed likewise; this also
  875       affects *pipe-TYPE/SUBTYPE*#502 and *pipe-EXTENSION*#509 (with
  876       legacy compatibility and -v/-d obsoletion warnings)!
  877 
  878         ? mimetype ?t text/x-awk  awk
  879         ? wysh set pipe-application/pdf='?=&?\
  880             trap "rm -f \"${MAILX_FILENAME_TEMPORARY}\"" EXIT;\
  881             trap "trap \"\" INT QUIT TERM; exit 1" INT QUIT TERM;\
  882             mupdf "${MAILX_FILENAME_TEMPORARY}"'
  883 
  884     + `vexpr'#303 (and `csop'#167) modifiers changed likewise.
  885       The case-insensitive subcommands "ifind" and "iregex" have
  886       been obsoleted, just use the ?[case] modifier to the regular
  887       function instead.
  888 
  889       P.S.: Thanks to Rich Felker the `regex' subcommands now
  890       works as desired even with empty intermediate submatches.
  891 
  892   o Changed address parse mode for command line arguments plus.
  893     This modifies decade old tradition, but results in a more
  894     predictable behaviour i think.  Most people will possibly even
  895     be surprised to see the old behaviour:
  896 
  897       $ </dev/null s-nail-old -dsubject ' du , de <p@p> , pp , du '
  898       -> To: du, de <p@p>, pp
  899     new:
  900       $ </dev/null s-nail -dsubject ' du , de <p@p> , pp , du '
  901       -> To: "du , de , pp , du " <p@p>
  902 
  903     Of course anything but perfect, our address parser is very
  904     complicated yet far from being acceptable.  (Dr. Werner Fink)
  905     This affects:
  906 
  907     + -b#60, -c#62 and To: receivers, as above.
  908       (We also have a new -T#82 receiver multiplexer, which is
  909       configurable in this regard, please see below for more.)
  910 
  911     + The -r#79 address.
  912       This saw more changes: the content is no longer evaluated
  913       via shell expression parser (when *v15-compat* is set)..
  914       unless explicitly requested via the *expandaddr*#417
  915       flag "shquote".
  916 
  917     + *sender*#543 variable.
  918 
  919     + `addrcodec'#143 command, likewise; old:
  920         ? addrc e du , e <w@d> , d
  921         du , e <w@d> , d
  922         #?1!22/INVAL
  923       new:
  924         ? addrc e du , e <w@d> , d
  925         "du , e , d" <w@d>
  926         #?0!0/NONE
  927 
  928     + `digmsg'#175 and `~^'#320 now use this parse mode fix for
  929       headers which need a single receiver, which is backward
  930       compatible but now safer since it can be fooled less easily
  931       (to split into a list what should be a single address, as
  932       shown above for `addrcodec'#143).
  933 
  934       They now can also be forced to use that parse mode for To:,
  935       Cc:, Bcc: with a new question mark modifier "?single", here
  936       the word "single" is optional.
  937 
  938        ~^ header insert To?single: exa, <m@ple>
  939        ~^ header show to
  940 
  941 - By established rules and popular demand occurrances of '^From_'
  942   (see *mbox-rfc4155*#464) will be MBOXO quoted (prefixed with
  943   greater-than sign '>') instead of causing a non-destructive
  944   encoding like 'quoted-printable' to be chosen, unless context
  945   (e.g., message signing) requires otherwise.
  946   Only with *mime-encoding*#473=8bit.
  947 
  948 - We now support long "Options"#5 -- try --long-help.
  949 
  950 - Finally, it is possible to force sending out messages with the
  951   new *mime-force-sendout*#474 variable.  If this MUA has been
  952   compiled with iconv(3) support it can happen that sending
  953   otherwise valid text messages fails because of invalid bytes
  954   sequences according to the locale; setting this new variable
  955   will avoid this; use *mime-counter-evidence*#472 to view such
  956   messages nonetheless.  (Dr. Werner Fink)
  957 
  958 ChangeLog
  959 ^^^^^^^^^
  960 
  961 - `mimeview'#227 works again with binary formats.  (Russell Bell)
  962 
  963 - IMAP searches via IMAP without matches no longer report a single
  964   match.  (Dirk-Wilhelm Peters)
  965 
  966 - New -Y#88 aka --cmd= option to inject commands to be executed
  967   when startup is completed (as opposed to the earlier -X#87 aka
  968   --startup-cmd=).
  969   These commands appear as if the user had typed them in.
  970 
  971 - A new *on-history-addition*#494 can be used to filter what
  972   enters the `history'#213.
  973 
  974 - New "fcc" flag for *expandaddr*#417.  (Olav Mørkrid)
  975 
  976   And "domaincheck" will cause target domain comparison against
  977   entries in the new *expandaddr-domaincheck*#418.  (Olav Mørkrid)
  978 
  979 - New *mbox-fcc-and-pcc*#463 will write out file and pipe addresses
  980   as a plain RFC5322 message rather than an MBOX.  (Olav Mørkrid)
  981 
  982 - The `errors'#191 queue existance and size is announced via
  983   *^ERRQUEUE-EXISTS*#355 and *^ERRQUEUE-COUNT*#354.
  984   (Russell Bell, Martin Neitzel)
  985 
  986 - Our MBOX parser is now truly compliant to POSIX.
  987   (Dr. Werner Fink)
  988 
  989 - We follow symbolic links again when writing files.
  990   (Russell Bell)
  991 
  992 - *tls-rand-file*#598 is in fact now necessarily one of the
  993   optional *tls-features*#595.  (Mike Sharov)
  994 
  995 - New command line option -T#82 aka --target='FIELD: BODY'.
  996   FIELD can be To:, Cc:, Bcc: or Fcc:.
  997   The BODY is parsed as a list (just as if the given FIELD would
  998   be part of a template message fed in via -t#83), but the
  999   "?single" modifier suffix can be used to avoid this.

 1004 v14.9.11 ("Tit family enjoying a bath"), 2018-08-08
 1005 ---------------------------------------------------
 1006 
 1007 A hot summer bugfix release, but it surely brings in some new
 1008 features, like TLS fingerprinting and `digmsg' message access.
 1009 
 1010 An embarassing number of bugfixes have been seen, to fix IMAP UID
 1011 handling on 32-bit hosts, UTF-8, `readall' with empty lines, rare
 1012 endless iconv(3) loops, false qsort(3)ing of addressee lists,
 1013 crashes due to false user shell quoting, acceptance of "0" port
 1014 numbers, and more.  Most of these cases now have tests.

 1025 
 1026 NOTES, ChangeLog (packager-affine)
 1027 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1028 
 1029 - I have discovered that GnuPG can --export-secret-subkey so that
 1030   the real/full private key is no longer needed to --sign, and the
 1031   excerpts of the private one can have a different password, too.
 1032   So i have created a new for-signing subkey: EEC8C2FF.
 1033 
 1034   Unfortunately it is not possible to verify new signatures with
 1035   the old public key, an update is necessary.  For example via
 1036     https://ftp.sdaoden.eu/steffen.asc
 1037   or just update 1883A0DD via normal gpg(1).
 1038 
 1039 - Maildir support is now optional but default via OPT_MAILDIR.
 1040   (Paride Legovini)
 1041 
 1042 - I hope for the last time there has been a change to SSL
 1043   configuration: i have renamed all ssl* variables to tls*.
 1044   The old ssl* ones still exist until v15, though, yet obsoletion
 1045   warnings will be produced.
 1046   This is so because i expect that in a not too distant future
 1047   only the term TLS will be around.
 1048 
 1049   Also the term CipherList was falsely used, it should have been
 1050   CipherString.
 1051 
 1052 - Most (if not all) commands which take a message list and a file
 1053   target now use shell-style quoting.  (Before that say `copy'#166
 1054   scanned backwards over "something possibly quoted", took that
 1055   off, then treated the rest as a message list.  Now shell tokens
 1056   are parsed starting at the front, the last is taken off, and
 1057   anything before that is the message list.)  (Gavin Troy.  2013.)
 1058 
 1059 - `~^#'? "header show" now backward-incompatibly shows the address
 1060   type in field 1, but since this _only_ applies to non-network
 1061   addresses i made the change.
 1062 
 1063 - We will find ncurses on DragonFly BSD.
 1064 
 1065 - On Solaris tests no longer need GNU cksum(1): the Solaris cksum
 1066   is different only for whitespace separators.  (Jörg Schilling)
 1067 
 1068 - All generated files reside in .obj/, and the tests run in there,
 1069   too.  A "rm -f .obj" should suffice to clean anything up.
 1070 
 1071 ChangeLog
 1072 ^^^^^^^^^
 1073 
 1074 - `~F'#327, `~f'#328, `~M'#333, `~m'#334, `~U'#342 and `~u'#343
 1075   now default to the current message (the "dot").  (Andrew Gee)
 1076 
 1077 - *indentprefix*#450 handling has had its pitfalls when quoting
 1078   messages.  (Andrew Gee)
 1079 
 1080 - -r#79 will again set *from*#432 even after -S#80 has been used
 1081   to set *from*.  (Michael Dressel)
 1082 
 1083 - No longer process From: (*from*#432) content via `alternates'#146
 1084   when Sender: (*sender*#543) is set.  (Michael Dressel)
 1085 
 1086 - Because the priority class of headers was not taken into
 1087   account, it could happen that addressees in Cc: would remain but
 1088   the same in To: were removed.  (Michael Dressel)
 1089 
 1090 - IMAP accounts for RFC 4551 (and 7162) and supports 64-bit
 1091   UIDVALIDITY.
 1092 
 1093 - *spamfilter-rate-scanscore*#580 could crash if specification
 1094   did not match program output.
 1095 
 1096 - Shims for TLSv1.3 support, e.g., for *tls-config-pairs*#592.
 1097 
 1098 - Obsoleted *dotlock-ignore-error*, added *dotlock-disable*#410.
 1099   (Paride Legovini)
 1100 
 1101 - In compose-mode, removing the In-Reply-To: header breaks an old,
 1102   and starts a new thread.  (Doug McIlroy)
 1103 
 1104 - Added new *forward-inject-tail*#431, *quote-inject-head*#525
 1105   and *quote-inject-tail*#526 variables, and extended the meaning
 1106   of *quote*#520.
 1107 
 1108   All of *{forward,quote}-inject-{head,tail}* now support
 1109   a compose-mode specific set of formats (see
 1110   *quote-inject-head*#525), for now a few only.
 1111   (This adds meaning onto the content of *forward-inject-head*#430
 1112   as introduced in v14.9.0.)
 1113 
 1114   The generated output honours *quote-fold*#524, which now takes
 1115   an optional third argument in order to produce better output.
 1116 
 1117   While here, introduce the new command escape `~Q'#336 which
 1118   performs full *quote*#520 cycles on the given message list.
 1119 
 1120 - Fcc: headers are now understood in -t#83 templates or when
 1121   placed in compose mode (`~v'#344, *editalong*#411 etc.).
 1122   Since each such header only takes one addressee, no quoting
 1123   issues apply, the entire header body is the value.
 1124 
 1125 - `~|'#319 will pass the entire message including headers when
 1126   used as "~||", e.g., prepend a file-carbon-copy message header:
 1127 
 1128     ~|| echo Fcc: /tmp/test; cat
 1129 
 1130 - New `tls'#289 multiplexer command.  Yet primitive and only
 1131   supports a `fingerprint' subcommand.  Supports `vput'#130.
 1132 
 1133   The new *tls-fingerprint*#596 variable chain aids in adding
 1134   support for connection verification without an installed CA
 1135   certificate pool in conjunction with the new
 1136   *tls-fingerprint-digest*#597 chain.
 1137 
 1138   Consequently *smime-sign-message-digest* has been renamed to
 1139   *smime-sign-digest*#563 (old version will cease in v15).
 1140   The latter now defaults to SHA512 if possible.
 1141 
 1142 - New MLE commands mle-go-screen-bwd and mle-go-screen-fwd to go
 1143   backward and forward one screenful.
 1144   And a new mle-clear-screen command.  (Todd C. Miller)
 1145 
 1146 - New *expandaddr*#417 setting "shquote" will evaluate addresses
 1147   as if specified within $'' shell-quotes for -b#60, -c#62,
 1148   and all direct command line receivers.  This allows for, e.g.,
 1149 
 1150     $ s-nail -Sexpandaddr=shquote '\$contact-mail'
 1151 
 1152 - *quote-as-attachment*#522 no longer needs to be set before
 1153   compose mode is entered in order to become honoured.
 1154 
 1155 - Even for -H#69 or -L#72 *folder-hook*#423s will now be called.
 1156   Possible sorting is also applied.
 1157 
 1158 - `='#138 now optionally supports message list arguments and the
 1159   `vput'#130 modifier in order to store the result list.
 1160 
 1161   The new `digmsg'#175 multiplexer adds some message access, just
 1162   like `~^'#320 does in compose mode.  In fact the set of commands
 1163   is shared, yet only in compose mode `digmsg' can change messages
 1164   or access attachments until v15, however.  For example,
 1165 
 1166   #?0[steffen@essex nail.git]$ cat > /tmp/z.rc <<'_EOT'
 1167   define one {
 1168      if [ "${#}" -gt 0 ]
 1169         digmsg create $1 - # no `read'/`readall' overlay but stdout
 1170         #digmsg $1 header list
 1171         digmsg $1 header show subject
 1172         digmsg remove $1
 1173         shift
 1174         \eval xcall one "$@"
 1175      \end
 1176   }
 1177   define all {
 1178      local set all # localize ("localopts yes" would do too)
 1179      vput = all *; echo all: $all; eval call one $all
 1180   }
 1181 _EOT

 1199 v14.9.10 ("(40th Mail anniversary) Blue tit"), 2018-03-25
 1200 ---------------------------------------------------------
 1201 
 1202 On this day in 1978 Kurt Shoens placed the following comment in
 1203 def.h (now it is in nail.h):
 1204 
 1205   /*
 1206    * Mail -- a mail program
 1207    *
 1208    * Author: Kurt Shoens (UCB) March 25, 1978
 1209    */
 1210 
 1211 v14.9.10 is mostly a stability and bugfix release.
 1212 It has seen a full test series including Coverity.com scans.
 1213 It fixes bugs i have introduced (also a double free in IMAP cache
 1214 that i introduced for v14.9.* series to address Coverity CID
 1215 1376978..).
 1216 
 1217 In the end i am saying thanks to Gunnar Ritter for the IMAP
 1218 module, and absolutely especially his really neat idea of an IMAP
 1219 cache including offline work queue.  (IMAP will nonetheless
 1220 temporarily go in v15, but these ideas will come back thereafter.)
 1221 I have gray hairs now.

 1227 A special credit to Coverity.com again.  Because:
 1228     tcc is 618496 bytes, pcc is 851968+24576 bytes,
 1229     but gcc is 73355264 bytes and clang is even
 1230     147406848 bytes, i wonder why the latter two never
 1231     said a word that would have addressed the pretty
 1232     obvious CID 1387053!

 1237 NOTES, ChangeLog (packager-affine)
 1238 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1239 
 1240 - The balls are now build with umask 0022 not 0027.
 1241   (William Yodlowsky, Stuart Henderson)
 1242 
 1243 - One actual development of this version was the addition of
 1244   multiple choice VAL_ues, as documented in make.rc.
 1245   For now we have VAL_IDNA (for OPT_IDNA)
 1246     VAL_IDNA="idnkit idn2 idn"
 1247   and VAL_RANDOM (by itself)
 1248     VAL_RANDOM="arc4 ssl libgetrandom sysgetrandom urandom builtin"
 1249   (Stuart Henderson)
 1250 
 1251   In brief:
 1252     The value is interpreted as a whitespace separated list of
 1253     strings, like "idn2 idn idnkit", case is ignored, order is
 1254     important.
 1255     The special strings "all" and "any" as well as the empty value
 1256     are wildcard matches; if any entry in the list is a wildcard
 1257     match, the rest of the list is ignored.
 1258 
 1259     The special string "error" will abort configuration once its
 1260     list position is reached; this is only supported if
 1261     documented, and not with an accompanying OPT_ (which then
 1262     offers "require", as below).
 1263 
 1264   Since this VAL_RANDOM approach is so much better i have dropped
 1265   OPT_SSL_RANDOM and OPT_NOEXTRANDOM that were recently
 1266   introduced again.  They were c..p.
 1267 
 1268 - Support for idnkit 2.3 has been added.
 1269   Support for idnkit 1 (especially as idnkitlite) has been fixed.
 1270 
 1271 - For the first time this codebase should be able to handle
 1272   invalid MBOX mailboxes (produced by, e.g., dma(1)) gracefully.
 1273   I hope i have found all places (sic) where code has to be fixed.
 1274   E.g., "? copy * INVALID-MBOX" now works.
 1275   (Smalltalk already knew objects which know what they are doing
 1276   are for the better...  This is v15, then.)
 1277 
 1278 - P.S.: the two FreeBSD test failures are noted in INSTALL.
 1279 
 1280 ChangeLog
 1281 ^^^^^^^^^
 1282 
 1283 - *asksend*#369 will now really allow recomposing.
 1284 
 1285 - `help'#212 now supports recursive `commandalias'#163es, and
 1286   command self-recursion detection now works differently, it has
 1287   been false for something like
 1288 
 1289       commandalias x q; commandalias q echo au
 1290 
 1291   since q became expanded to `quit'#250 (alias expansion equals
 1292   new command word).  New behaviour: we allow equals once:
 1293 
 1294     commandalias q q; commandalias x q; x
 1295   ->
 1296     x -> q -> q -> quit
 1297 
 1298 - *editalong*#411 can have a value, say "set editalong=v" and it
 1299   will startup $VISUAL#640 not $EDITOR#617.
 1300 
 1301 - Path separators are now normalized, thus all places, including
 1302   MLE tab-expansion ("On terminal control and line editor"#18),
 1303   can expand something like "///t*////t*".
 1304 
 1305 - -E#65 flag will not be obsoleted.
 1306   -D#63 flag has been reintroduced (sets *disconnected*#666 right
 1307   away, was not reinstantiated with the rest of the IMAP support.)

 1311 v14.9.9 ("Marsh tit savours first spring sun, II") 2018-03-06
 1312 -------------------------------------------------------------
 1313 
 1314 A bugfix release.
 1315 I hope with this the fallout of the Christmas 2016 "address the
 1316 Dr. Problem workshop" has been fully resolved and thus MIME for
 1317 header address fields, even if iconv(3) is involved, been fully
 1318 restored!  We have even more tests for this now.
 1319 
 1320 The release v14.9.8 was broken on big endian machines.
 1321 I will remove the v14.9.8 balls from the server by the weekend.
 1322 Sorry for the inconvenience!

 1330 
 1331 NOTES, ChangeLog (packager-affine)
 1332 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1333 
 1334 - The v14.9.* series called *pipe-TYPE/SUBTYPE*#502 handlers in
 1335   display or quote mode with CR (carriage-return) bytes stripped
 1336   because of a missing output file comparison check, which broke
 1337   binary formats etc.  (Slavko)
 1338 
 1339 - We now have native support for Libidn2.  (Matej Mužila)
 1340 
 1341 - uname(1) is now hookable by setting the shell variable uname
 1342   when calling make ("uname=MY-UNAME make config" etc.).
 1343   (Simon McVittie)
 1344 
 1345   We no longer bake the kernel version into the binary, and
 1346   `version'#302 includes uname(2) output.
 1347   (Simon McVittie, Paride Legovini)
 1348 
 1349 - We now support a fallback P(seudo)R(andomNumber)G(enerator)
 1350   initialization even if getrandom(2)/getrandom(3) has been found
 1351   by the configuration, just like we do for "/dev/urandom" usage.
 1352   This does not affect systems with arc4random(3) or OpenSSL
 1353   random usage.  (David Čepelík, Simon McVittie)
 1354 
 1355   A new OPT_SSL_RANDOM make.rc variable, by default initialized to
 1356   the value of OPT_SSL.
 1357 
 1358 ChangeLog
 1359 ^^^^^^^^^
 1360 
 1361 - `~@'#318 list-edit behaviour in -##90 batch mode was broken.
 1362 
 1363 - Character set names will now undergo generic normalization,
 1364   including stripping of iconv(3) //SUFFIXes.

 1368 v14.9.7 ("Marsh tit patiently scraping bark") 2018-02-16
 1369 --------------------------------------------------------
 1370 
 1371 A maintenance release which fixes bugs and brings in features.
 1372 
 1373 Credits, in order of commit appearance: Alexander Harm,
 1374 Viktor SZÉPE, Paul Eggert, Joseph Bisch, Paride Legovini,
 1375 and Peter J. Holzer.
 1376 A special credit to the disappearing mutt(1) bug tracker.
 1377 And to Gmane.org for creating gmane.mail.s-mailx.general!
 1378 
 1379 Thanks Paride Legovini for becoming maintainer of the Debian port.
 1380 
 1381 We welcome Joseph Bisch, Paride Legovini, and Peter J. Holzer in
 1382 THANKS.
 1383 
 1384 NOTES, ChangeLog (packager-affine)
 1385 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1386 
 1387 - The USB stick loss reported for v14.9.6 was fake news, so to
 1388   say, the stick exists and therefore the old key is not
 1389   compromised.
 1390 
 1391 - We are back at Gmane.org!
 1392     news.gmane.org/gmane.mail.s-mailx.general
 1393 
 1394 - `history'#213 has learned to be context-sensitive a bit, and
 1395   has two new subcommands, `load' and `save'.
 1396 
 1397     This is in parts backward incompatible because it needs a new
 1398     *history-file*#438 format; however, the old format can be loaded
 1399     yet compose-mode commands will not appear in compose mode no
 1400     more.  Iirc you can start with an old format then `save' to
 1401     the new, then replace the "d" in the first column with "c" for
 1402     compose-mode commands which should appear correctly.
 1403 
 1404 - Obsoletion warnings for variables now happen at `set'#269
 1405   time instead of when used.  Running once via -v#86 may
 1406   be beneficial.
 1407 
 1408 - The saturation modifier of `vexpr'#303 is henceforth a prefix,
 1409   the suffix version is obsolete (but still supported for a while).
 1410 
 1411 - A network address that contains no domain-, but only a valid local
 1412   user <name> in angle brackets will be automatically expanded to
 1413   a valid address when *hostname*#443 is set to a non-empty value;
 1414   setting it to the empty value instructs us that the used *mta*#476
 1415   (including builtin SMTP) will perform the necessary expansion.
 1416   (Viktor SZÉPE)
 1417 
 1418   Note that *hostname*#443 as well as *smtp-hostname*#566
 1419   will now undergo IDNA expansion if IDNA is supported.
 1420 
 1421   And *from*#432 and *sender*#543 are now verified at `set'#269
 1422   time, not when used.  (Viktor SZÉPE)
 1423 
 1424 - The commit message in [d503bd82] is wrong, apologies to
 1425   Paride Legovini.  The test(1) operator "-n" appeared in Seventh
 1426   Edition UNIX, not V8 as falsely claimed.
 1427 
 1428 ChangeLog
 1429 ^^^^^^^^^
 1430 
 1431 - Our `addrcodec'#143 parser chokes on lesser constructs.
 1432 
 1433 - Presence of command-line MTA arguments without *expandargv*#419
 1434   are now a hard error.  It was my fault that this was not the
 1435   default from the very start.  (Viktor SZÉPE)
 1436 
 1437 - Seen on the mutt bug tracker, we also still have had problems
 1438   with time settings that cross 32-bit boundaries.  As that is
 1439   in parts induced by the C standard, now implement those parts on
 1440   our own, and be super careful in general.  (Joseph Bisch)
 1441 
 1442 - The `~@'#318 command escape did not shell-unquote the user input
 1443   again and was thus a bit broken; message attachments also work
 1444   again.
 1445 
 1446 - Support custom headers from the command line via -C#61.
 1447   And *customhdr*#404 is verified upon `set'#269 time.
 1448 
 1449 - The simple builtin HTML viewer now supports <blockquote>
 1450   elements, which many web mailers, most notably gmail, use for
 1451   citation.  (Peter J. Holzer)

 1455 v14.9.6 ("Marsh tit abiding a snow storm"), 2017-12-05
 1456 ------------------------------------------------------
 1457 
 1458 A bugfix release which fixes four serious and three other bugs.
 1459 A few new features came in, too.
 1460 
 1461 Many thanks go to Ralph Corderoy who reported an issue that was
 1462 caused by a terrible, terrible word reversal that i managed to
 1463 produce in December 2016, and which caused the v14.9.x series to
 1464 not MIME encode (non-address) content of address header fields!

 1474 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1475 
 1476 - After USB stick loss the authors OpenPGP key has been switched to
 1477 
 1478     pub   4096R/1883A0DD 2017-11-30 [expires: 2027-11-28]

 1481     uid                  Steffen Nurpmeso <steffen@sdaoden.eu>
 1482 
 1483 - $TMPDIR#638 no longer honoured for root runs.  (Solar Designer)
 1484 
 1485 - *mime-encoding*#473 defaults to quoted-printable again.  (Cág)
 1486 
 1487 - We _can_ MIME encode even header fields which contain addresses.
 1488   Thanks to Ralph Corderoy we now also _do_ so again!
 1489 
 1490 ChangeLog
 1491 ^^^^^^^^^
 1492 
 1493 - ***#336 now uses *ifs*#445 when splitting.
 1494 
 1495 - Freezing *ttycharset*#602 via -S#80 also survives using or
 1496   setting any of $LC_ALL#619, $LC_CTYPE#620 and $LANG#621 during
 1497   program startup.
 1498 
 1499 - New `local'#127 command modifier to localize changes.
 1500   Yet supported only for `set'#269, i.e., we have gained
 1501   macro-local variables.
 1502 
 1503 - `vexpr'#303 now supports a BASE#number notation for integers,
 1504   like 16#AFFE as an alternative to 0xAFFE.
 1505 
 1506   Hint: variable settings can most often use several bases, too,
 1507   e.g., i have "set mime-counter-evidence=0b1111".
 1508 
 1509 - Very simple form of *quote-chars*#523 to adjust our knowledge of
 1510   what actually is to be treated as a quote character.
 1511 
 1512 - *mime-counter-evidence*#472 deep inspection (bit four) has
 1513   been improved for the sole cases of quoting or displaying
 1514   a message.  So messages with less than 25% of control characters
 1515   and such will now be displayed (made printable).  This is yet
 1516   not configurable nor do we have a way to easily access a message
 1517   with more than that.  (Doug McIlroy)

 1521 v14.9.5 ("Marsh tit engaged with a peanut"), 2017-10-21
 1522 -------------------------------------------------------
 1523 
 1524 A bugfix release which fixes two bugs which were cast in stone.
 1525 A few compatibility improvements (AlpineLinux, Solaris).
 1526 And minor features.
 1527 
 1528 Apologies to Jörg Schilling, a git bug i think it was who caused
 1529 joining of changesets, losing a credit, and it had been pushed to
 1530 [master] before the problem was realized.

 1536 
 1537 NOTES, ChangeLog (packager-affine)
 1538 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1539 
 1540 - New OPT_USE_PKGSYS option can be disabled to not automatically
 1541   pick known package system paths (pkg(7), OpenCSW, schily).
 1542   (Jörg Schilling)
 1543 
 1544 ChangeLog
 1545 ^^^^^^^^^
 1546 
 1547 - The software indeed _never_ dealt with iconv(3) output character
 1548   set errors (as opposed to invalid input character set byte
 1549   sequences etc.) for the main message body!
 1550   And I have missed that when i tweaked our iconv layer a bit!
 1551 
 1552 - Fixed a race condition with sigsuspend(2) that i could only see
 1553   on OpenBSD.  config.h offers n_SIGSUSPEND_NOT_WAITPID, by the
 1554   way, which saves some systemcalls and did not run races, but
 1555   noone adjusts this file.
 1556 
 1557 - Message list specifications gained two new colon modifiers, one
 1558   can now "search :Ll" to find "Mailing lists"#11.
 1559   The *headline*#435 format %T now also uses L and l rather than
 1560   S and L accordingly.
 1561 
 1562   New `addrcodec'#143 subcommand `skinlist' acts like `skin'
 1563   but stores in *!*#349 *^ERR*#351-EXIST if the address is
 1564   one of the known "Mailing lists"#11.
 1565 
 1566 - `echo'#182 family now supports `vput'#130 and *!*#349 error
 1567   storage, offering some kind of printf(1) experience, almost.

 1572 ---------------------------------------------------
 1573 
 1574 This is an update feature release but which also ships a furious
 1575 number of bug fixes, about six of which were pretty serious.  It
 1576 also applies overall trimming, and improves configuration time
 1577 compatibility on macOS.
 1578 
 1579 Thanks to Alexander Harm there is now a macOS Homebrew package.

 1588 
 1589 NOTES, ChangeLog (packager-affine)
 1590 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1591 
 1592 - Out-of-tree builds have become possible via the new
 1593   make-emerge.sh script:
 1594 
 1595   $ cd /tmp && mkdir build && cd build &&
 1596     ~/src/nail.git/make-emerge.sh &&
 1597     make tangerine DESTDIR=.ddir
 1598 
 1599   We now have a `citron' make target which is like `tangerine' but
 1600   does not run the tests.
 1601 
 1602 - Configuration with OPT_AUTOCC honours $CC=cc. (Norman Ramsey)
 1603 
 1604 - SSL/TLS configuration has been revamped (again) in order to
 1605   support new possibilities of OpenSSL (and LibreSSL) without
 1606   ending up and introducing more and more variables.
 1607 
 1608   Instead we now have *ssl-config-pairs*, a comma-separated
 1609   list of all options.  With e.g. OpenSSL 1.1.xx this will be
 1610   directly passed through to SSL_CONF_cmd(), so there _anything_
 1611   can be passed, otherwise we use a builtin parser to map.
 1612   The new *ssl-features*#? states what is supported.  E.g.:
 1613 
 1614     if [ "$ssl-features" =% +ctx-set-maxmin-proto ]
 1615       wysh set ssl-config-pairs='\
 1616           CipherList=TLSv1.2:!aNULL:!eNULL:@STRENGTH,\
 1617           Curves=P-521:P-384:P-256,\
 1618           MinProtocol=TLSv1.1'
 1619     else
 1620       wysh set ssl-config-pairs='\
 1621           CipherList=TLSv1.2:!aNULL:!eNULL:@STRENGTH,\
 1622           Curves=P-521:P-384:P-256,\
 1623           Protocol=-ALL\,+TLSv1.1 \, +TLSv1.2'
 1624     endif
 1625 
 1626   OpenSSL v1.1.xx also introduces an interesting and neat idea to
 1627   centralize SSL/TLS configuration of (all) programs in a single
 1628   file.  This can be driven via *ssl-config-file* and the new
 1629   *ssl-config-module* variables, several entries per program
 1630   are allowed, see *ssl-config-module* for an example.
 1631 
 1632   New manual section "Encrypted network communication"#14.
 1633 
 1634 - Variables set or unset via -S#80 are now frozen until program
 1635   startup is complete.
 1636 
 1637 ChangeLog
 1638 ^^^^^^^^^
 1639 
 1640 - Historical behaviour of *askcc*#367 / *askbcc*#368 has been
 1641   reintroduced.  (Norman Ramsey)
 1642 
 1643   A new *asksend*#369 variable will show a final header summary
 1644   and allows reentering compose mode.  Set by default.
 1645 
 1646   POSIX mirrors *ask* onto *asksub*#371, so dropped" the former.
 1647 
 1648 - `~^'#320 no longer normalizes header names to titlecase.
 1649 
 1650 - We no longer generate charset=binary MIME parameters.
 1651   This was introduced on 2013-01-02 and was i think owed to
 1652   file(1)s -i output as i failed to find any other reference.
 1653   (Normal Ramsey)
 1654 
 1655 - *mime-alternative-favour-rich*#471 now also works for handlers
 1656   installed via *pipe-TYPE/SUBTYPE*#502. (Viktor Szépe)
 1657 
 1658 - v14.9.* series did not generate In-Reply-To: headers!
 1659 
 1660 - `alias'#144 now supports high-bit bytes and semicolon.
 1661   Expect that at some later time the input must be valid according
 1662   to the locale, though. (Norman Ramsey)
 1663 
 1664 - Combinations of *record*#529 could crash because of an
 1665   unterminated variable function argument list. (Norman Ramsey)
 1666 
 1667 - New command `readall'#253 loads an entire file into a variable.
 1668 
 1669   *signature*#550 has been obsoleted.
 1670 
 1671 - `vexpr'#303 now supports negative arguments for the substring
 1672   subcommand and adds trim, trim-front and trim-end subcommands.
 1673 
 1674 - `!'#134 can be used in send mode.
 1675 
 1676 - `~A'#321, `~a'#322, `~I'#331 and `~i'#332 will henceforth expand
 1677   \t and \n only if *posix*#515 is set.
 1678   Please use `set'#269 instead (with `wysh'#131, until v15).
 1679 
 1680 - New "The mime.types files"#36 type marker: @q ("quiet").

 1684 v14.9.3 ("Crested tit nibbling sunflower seeds"), 2017-08-03
 1685 ------------------------------------------------------------
 1686 
 1687 This is a bugfix release but which ships some improvements, too.
 1688 It silently replaces both of v14.9.1 v14.9.2 from earlier this

 1700 
 1701 NOTES, ChangeLog (packager-affine)
 1702 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1703 
 1704 - fakeroot support was blindly taken from Debian and broken.
 1705   (Gavin Troy, Gaetan Bisson)
 1706 
 1707 - Base64 output was broken for cases which involved iconv(3).
 1708   The data is not lost, you can read it with S-nail v14.9.0 and
 1709   above, and save it somewhere.  I know of no other base64 decoder
 1710   which reads those things correctly, though.  We now have tests.
 1711   Along this i fixed an iconv(3) error which likely caused
 1712   stateful decoding (like, e.g., for ISO-2022-JP) to fail because
 1713   of an unnecessary reset of the iconv(3) state machine.
 1714   Thanks to Gaetan Bisson for mentioning this issue!
 1715 
 1716 ChangeLog
 1717 ^^^^^^^^^
 1718 
 1719 - In compose mode the MLE allows empty lines again.
 1720 
 1721 - We no longer require a writable $HOME#618.  Due to false code
 1722   flow (but but but: with correct comment) a non-writable $HOME
 1723   entry in /etc/password (i.e., from getpwuid(3)) would lead to
 1724   a crash.  (Felix Fontain; Ralph Corderoy)
 1725 
 1726 - Two faulty string operations slipped into the IMAP code,
 1727   resulting in a crash and a "is-same-host" test that would fail
 1728   for IMAPS connections like `save'#266 or `copy'#166 because of an
 1729   implicit IMAP protocol for the target of those operations (thus
 1730   IMAP != IMAPS).  (Paul Vojta)
 1731 
 1732 - The MLE tab-expansion will now automatically append a "/" if
 1733   there is only one possible expansion and that is a directory,
 1734   saving the user one <TAB>.  (Christos Zoulas)
 1735 
 1736   The shell expression parser had a bug regarding understood
 1737   metacharacters (;|&), which in turn could cause an infinite loop
 1738   in the MLE tab-expansion for, e.g., "move &9 +<TAB>", because
 1739   the "&" would never have been stepped over.
 1740 
 1741 - New `~I'#331 command escape is like `~i'#332 but does not append
 1742   a newline.
 1743 
 1744 - `localopts'#218 gained an optional second argument.
 1745   It is now possible to specify that any macro `call'#152ed
 1746   will have localopts enabled, and it is possible to fixate the
 1747   setting so that it cannot be reverted.
 1748 
 1749 - *@*#357 should now act completely compatible to the sh(1)ell,
 1750   thus obsoleting my hysteric warnings in the v14.9.0 announcement.
 1751 
 1752 - The `Lreply'#220, `reply'#259, `Reply'#257 series as well as
 1753   `mail'#222 now manage the error status *!*#349.
 1754   I.e., there are now errors like *^ERR*#351-DESTADDRREQ,
 1755   ^ERR-NODATA, ^ERR-PERM and similar.  It is not perfect yet,
 1756   because $DEAD#616 may have been written (with *save*#538) or not,
 1757   for example.
 1758 
 1759   `Lreply' and `reply' have been rewritten rather completely
 1760   indeed.  They join Reply-To: and Mail-Followup-To: dependent on
 1761   the context (i.e., *reply-to-honour*#535, *followup-to-honour*#427,
 1762   see "Mailing lists"#11 for the picture), and if they did, use
 1763   this list as the receivers exclusively.  It now honours
 1764   *recipients-in-cc*#528 even for such addressees.  (And now i wonder
 1765   whether i should have credited Paul Vojta for that.)
 1766 
 1767   Also `Lreply' would have crashed for mails with Reply-To: but
 1768   without *reply-to-honour*#535 set.  We now have a test.
 1769 
 1770   Note *replyto* is obsoleted in favour of *reply-to*#534.
 1771 
 1772 v14.9.0 ("Long-tailed tit"), 2017-07-16
 1773 ---------------------------------------
 1774 
 1775 This is a major feature release which took about ~22 months (24
 1776 less two) of development to complete, and which imposed massive
 1777 changes under the hood, but also quite a lot of user visible
 1778 changes, including some **backward incompatibilities**.
 1779 As usual, "s-nail -d" will show obsoletion warnings.
 1780 
 1781 We gain noticeable improvements regarding scriptability and its
 1782 reliability, but also for interactive use cases, especially
 1783 notable to users is our completely new M(ailx)L(ine)E(ditor) that
 1784 supports rather real tabulator expansion and program-mode-context-
 1785 sensitive key bindings.
 1786 
 1787 We now support macros with arguments, which can be `shift'ed,
 1788 a `return' status can be used, and a `vexpr' multiplexer offers
 1789 some arithmetic and string operations.  `commandalias'es are
 1790 recursive, further command modifier prefixes, like `ignerr', give
 1791 a hand that we otherwise could not offer.  In compose-mode the new
 1792 `~^' command escape allows some message and attachment access, and
 1793 can be used, e.g., to implement things like custom headers, and
 1794 has been especially designed for scripted access via the new
 1795 *on-compose-splice* and *on-compose-splice-shell* hooks.
 1796 
 1797 S-nail will move (more or less) backward-incompatibly to sh(1)ell
 1798 compatible argument quoting (documented in "COMMANDS"), and an
 1799 increasing number of commands do support this already: new ones
 1800 exclusively, some old ones have either been switched (like
 1801 `localopts'), others -- noticeably `set' -- can be switched to the
 1802 new syntax with a `wysh' command modifier prefix.  E.g.:
 1803 
 1804   ? define __xv {
 1805     # Be careful to choose sh(1)ell-style on _entire_ line!
 1806      localopts yes; wysh set verbose; ignerr eval "${@}"; return $?
 1807     }
 1808   ? commandalias call echo boo-boo
 1809   ? commandalias xv call __xv
 1810   ? xv list
 1811   ? commandalias xv '\'call __xv
 1812   ? xv list
 1813 
 1814 Calling the latter `xv' for `list' will give more detailed command
 1815 information, including which kind of argument is used.
 1816 
 1817 I have not managed to implement the three features i have started
 1818 this development cycle for, these are thus subject to further
 1819 development, just like wysh for message-list argument commands to
 1820 support, e.g., negation, wysh for `if' and consorts, the --
 1821 terminator to finally overcome the ridiculous requirement to quote
 1822 entire shell commands filenames for commands like `pipe.
 1823 And and and.

 1852 NOTES, ChangeLog (packager-affine)
 1853 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 1854 
 1855 * This release brings some backward incompatibilities, outlined
 1856   in the following.  Most users will not be affected, and we have
 1857   added a lot of compatibility cruft, but that will vanish in v15.
 1858   "$ s-nail -v"!
 1859 
 1860 * The configuration and build system has changed.
 1861   Packagers have received updated package files.
 1862 
 1863   o Anything which was WANT_xy before is now OPT_xy, and
 1864     compiled-in paths and values, like PREFIX or PAGER, have
 1865     gained a VAL_ prefix (thus VAL_PREFIX and VAL_PAGER).
 1866 
 1867     This is _not_ true for non-persistent or environmental values,
 1868     e.g., DESTDIR, CC, etc., and also not for the overwritable
 1869     program variables during configuration, e.g., $awk.
 1870 
 1871   o SENDMAIL -> VAL_MTA, SENDMAIL_PROGNAME -> VAL_MTA_ARGV0,
 1872     MAILSPOOL -> VAL_MAIL.
 1873     And NAIL -> VAL_MAILX, though this is still a lie.
 1874 
 1875   o The make system now needs config..build..install or
 1876     all..install or tangerine (config..build..test..install).
 1877     Some constants which some experts may want to fine-tune have
 1878     been moved to config.h.  Usual adjustments+doc via make.rc.
 1879 
 1880   o The `build' phase can be parallelized by setting the $MAKEJOBS
 1881     environment variable, e.g., "make MAKEJOBS=-j4 build".
 1882     Note this variable is not tracked in the configuration.
 1883     (Gaetan Bisson)
 1884 
 1885   o Unless DESTDIR is set an uninstallation script will be
 1886     installed along with the rest (see INSTALL file for more).
 1887 
 1888   o Set the new OPT_CROSS_BUILD to avoid feature runtime tests,
 1889     only compile- and link-availability will be tested.  (Juan RP)
 1890 
 1891   o VERBOSE is implemented straight, but must be given at
 1892     configuration time in order to become honoured.
 1893     (William Yodlowsky)
 1894 
 1895   o ADDCFLAGS / ADDLDFLAGS -> EXTRA_CFLAGS / EXTRA_LDFLAGS.
 1896 
 1897   o The LD_LIBRARY_PATH etc. building processes will skip any path
 1898     which contains the string "fakeroot".  (Hilko Bengen)
 1899 
 1900   o We honour a set $SOURCE_DATE_EPOCH#636 environment variable to
 1901     an extend that allows reproducible tests, which is why the
 1902     repository gained a [test-out] branch with some expected plain
 1903     text outputs.  (reproducible-builds.org; Colin Watson)
 1904 
 1905     The new *log-prefix*#457 variable aids in improving the
 1906     reproducibility of error messages.
 1907 
 1908   o These are upward compatible changes.
 1909 
 1910 * "make OPENSSL_API_COMPAT=0x10100000 all" should work.
 1911 
 1912 * Internal and environment variables are now explicitly _defined_
 1913   and _tracked_ after variable handling has been rewritten
 1914   completely.  Notes:
 1915 
 1916   o This means that, e.g., "$ password=NOT_SECRET s-nail" will
 1917     **NOT** work no more, since *password*#500 is an internal
 1918     variable!
 1919 
 1920   o But if you do, e.g., "? set TMPDIR=~/tmp", then this will
 1921     also be reflected in the program environment (it is an
 1922     environment variable) and thus affect child processes.
 1923 
 1924   o Therefore we no longer have `setenv' and `unsetenv'.
 1925 
 1926   o To integrate any other environment variable transparently
 1927     into our variable management, the new command `environ'#190
 1928     needs to be used, e.g., "? environ set NEWVAR=value" or
 1929     "? environ link EXISTINGVAR".
 1930 
 1931 - -H#69 and -L#72 have been decoupled:
 1932    it used to be -e#66 -L#72 instead!
 1933 
 1934 - *NAIL_{HEAD,TAIL}* have been obsoleted in favour of
 1935   *message-inject-head*#467 and *message-inject-tail*#468.
 1936 
 1937   *NAIL_HIST{FILE,SIZE}* have been obsoleted in favour of
 1938   *history-file*#438 and *history-size*#441.
 1939 
 1940   *NAIL_EXTRA_RC* has been obsoleted in favour of
 1941   *mailx-extra-rc*#461.
 1942 
 1943   *batch-exit-on-error* has been obsoleted by *errexit*#414, which
 1944   works just like the POSIX sh(1)ell "set -e" construct; the
 1945   `ignerr'#126 command modifier (`-' for command escapes in compose
 1946   mode, and see below) can be used to ignore command errors even
 1947   then.  (This will remain even if we at some later time will
 1948   support at least some of the sh(1) constructs which "swallow"
 1949   failures with set -e.)
 1950 
 1951   *bsdannounce* is obsolete, the feature is integrated in
 1952   *header*#434 as this is much more useful.  (This is however also
 1953   dependent upon the also new but well-known $POSIXLY_CORRECT#633
 1954   <> *posix*#515, but that is just how it is; these affect more
 1955   behaviour, and increasing.)
 1956 
 1957 - Colour support has been changed backward in- and upward (from
 1958   user interface side) compatibly, see the manual section
 1959   "Coloured display"#19.
 1960 
 1961   + New commands: `colour'#161 and `uncolour'#162.
 1962     You can define context-sensitive, terminal-capability-
 1963     sensitive settings, e.g.:
 1964 
 1965       if terminal && [ "$features" =% +colour ]
 1966         colour iso  view-header ft=bold,fg=magenta,bg=cyan
 1967         colour 256  view-header ft=bold,fg=208,bg=230 subject,from
 1968         colour mono view-header ft=bold
 1969         colour mono view-header ft=bold,ft=reverse subject,from
 1970       endif
 1971 
 1972   + The variable *colour-pager*#396 defines whether colour and font
 1973     attribute sequences should be generated when viewing something
 1974     in $PAGER#631.
 1975 
 1976   + Set the variable *colour-disable*#395 to turn colour off
 1977     without affecting established settings.
 1978 
 1979   + It is deduced via termcap(5) (see below) whether the terminal
 1980     supports colors, e.g., "$ s-nail -Stermcap=Co#256".
 1981     This is also true if we don't have termcap support.
 1982 
 1983   + Support for 256-colour terminals. (Gavin Troy)
 1984 
 1985 - `source'#281 series support shell pipes if the last character
 1986    of the "filename" ends with a vertical bar |, e.g.,
 1987 
 1988       ? source 'gpg -qd ~/.s-nailrc-private.gpg |'
 1989 
 1990 - Shell pipes are also supported as targets for `move'#233,
 1991   `copy'#166 etc., yet unfortunately not with via a sh(1)ell token
 1992   parser, so that the target still has to be a single argument.
 1993 
 1994       ? copy . '| cat; echo huhu'
 1995 
 1996 - Support for custom headers via the new `~^'#320 compose-mode
 1997   command escape and in addition, or alternatively, with the
 1998   internal variable *customhdr*#404, which also can be covered by
 1999   `localopts'#218.  (Sergey Matveev)
 2000 
 2001   + Support of $ORGANIZATION has been dropped.
 2002 
 2003   + Command escape `~e'#326 supports _any_ header.
 2004 
 2005   + Command escape `~^'#320 supports _any_ header.
 2006 
 2007 - New -:#56 command line option can be used to more easily select
 2008   which startup files should be loaded, e.g., -:/ loads none.
 2009   (Robert Elz)
 2010 
 2011 - `account'#141s and *folder-hook*#423s now have `localopts'#218
 2012    enabled by default.
 2013 
 2014 - A first simple form of compose-mode hooks has been implemented:
 2015   *on-compose-enter*#490, *on-compose-leave*#491 and
 2016   *on-compose-cleanup*#489 can be set to macros which get invoked
 2017   at appropriate times.
 2018   For the `resend'#262 series there is *on-resend-enter*#498 and
 2019   *on-resend-cleanup*#497: this is very likely to change once
 2020   true message access is possible even in this mode.
 2021 
 2022   An even more powerful mechanism is available via the also new
 2023   *on-compose-splice*#492 and *on-compose-splice-shell*#493 hooks.
 2024   These are executed in child processes and communicate with the
 2025   parent via their standard input and output, and therefore can
 2026   do anything and act as if they were the user.
 2027 
 2028   `localopts'#218 are enabled and cannot be disabled (and extend
 2029   until the message is sent).
 2030   (Jens Schleusener, Rudolf Sykora)
 2031 
 2032     ? set on-compose-splice=ocs
 2033     ? define ocs {
 2034       read ver
 2035       echo Splice protocol version is $ver
 2036       echo '~^header list'
 2037       read hl; vput vexpr es substring "${hl}" 0 1
 2038       if [ "$es" != 2 ]
 2039         echoerr 'Failed to read header list, bailing out'
 2040         echo '~x'
 2041       elif [ "$hl" @i!% ' cc' ]
 2042         echo '~^header insert cc Diet is your <mirr.or>'
 2043         read es; vput vexpr es substr "${es}" 0 1
 2044         if [ "$es" != 2 ]
 2045           echoerr 'Failed to insert Cc:, bailing out'; echo '~x'
 2046         end
 2047       end
 2048     }
 2049 
 2050 - "The .netrc file"#38
 2051 
 2052   + gained support for comments.
 2053     (Walter Alejandro Iglesias, Ralph Corderoy)
 2054 
 2055   + `netrc'#237 now has a "load" subcommand.
 2056 
 2057   + the new *netrc-pipe*#484 obsoletes OPT_AGENT and
 2058     *agent-shell-lookup*, and can be used to load an encrypted
 2059     .netrc file, e.g.:
 2060 
 2061       ? set netrc-lookup netrc-pipe='gpg -qd ~/.netrc.gpg'
 2062 
 2063     I.e., this is in usual .netrc syntax and thus possibly much
 2064     nicer than saying "? source 'gpg -qd ~/.credentials.gpg |'".
 2065 
 2066 - termcap(5) / terminfo(5) support has been changed backward in-
 2067   and upward (from user interface side) compatibly, please read
 2068   "On terminal control and line editor"#18.
 2069 
 2070   + OPT_TERMCAP is by default enabled.
 2071     The new, by default enabled, configuration option
 2072     OPT_TERMCAP_VIA_TERMINFO can be used to (try to) use
 2073     terminfo(5) instead.
 2074 
 2075   + The variable *termcap*#583 can be used to freely define or
 2076     override terminal capabilities, and *termcap-disable*#585 will
 2077     disable interaction with the chosen library, leaving only
 2078     *termcap* in charge.
 2079 
 2080     To use the so-called ca-mode on supporting terminals,
 2081     effectively turning S-nail into a fullscreen application,
 2082     *termcap-ca-mode*#584 must be set.
 2083 
 2084   + The built-in line editor has been rather completely rewritten
 2085     to be the Mailx-Line-Editor (OPT_MLE, default yes), and
 2086     supports wide glyphs (if possible), infinite line lengths
 2087     (2 GB) and more.  Tabulator expansion is no longer an option
 2088     (but needs fnmatch(3)).
 2089 
 2090   + Optionally (OPT_KEY_BINDINGS, default yes) it has become
 2091     possible to freely define key bindings for the MLE via the new
 2092     `bind'#150 and `unbind'#151 commands.  These key bindings can
 2093     make use of termcap(5) and/or terminfo(5) names.  The MLE will
 2094     install a set of default bindings (unless there is a set
 2095     *line-editor-no-defaults*#456), more so with OPT_TERMCAP,
 2096     i.e., try "? bind*".
 2097 
 2098     Sufficient support provided, one can now, e.g., type "p " and
 2099     then collect the message numbers to type, scrolling forward
 2100     and backward via key-bindings, without losing the line
 2101     content, then commit the final line.
 2102 
 2103   + OPT_EDITLINE and OPT_READLINE support have been dropped.
 2104     The new MLE should not miss anything.  Does it?
 2105     Tip: in an UTF-8 locale try "? !touch /tmp/hall{,öchen}" and
 2106     then autocomplete that: once, then ^Q, and again.
 2107 
 2108 - `source'#281 can be used in `call'#152ed macros.
 2109   What sounds so innocent replaced an entire machinery and got rid
 2110   of a brilliant idea of Kurt Shoens from the 70s, but which never
 2111   worked with Nail/Heirloom extensions, namely macros, and in the
 2112   right order.
 2113   Accompanying this -X#87 can (dig multiline arguments and can) be
 2114   used to define macros and run them etc.  Should work:
 2115 
 2116     $ s-nail -X'define x {' -Xversion -Xx -X'}' -X'call x'
 2117     $ s-nail -X'source \' -X'"echo version|"' -Xx
 2118 
 2119   Macros can be `undefine'#172d from within themselves, and re-
 2120   `define'#171d.  It is still not possible to define macros
 2121   from within macros, and/or have inner macros, not to talk
 2122   about local scoping or anything more sophisticated such.
 2123 
 2124 - -u#84 / $LOGNAME#624 ($USER) handling has been redefined,
 2125   and "-u USER" is now exactly the same as "-f %USER", and
 2126   $LOGNAME (and $USER) is actively set to the active user.  (Afan)
 2127 
 2128   $LOGNAME#624 is POSIX standardized and henceforth used and
 2129   preferred over $USER, which came from BSD.  (Todd C. Miller)
 2130 
 2131 - In the future (at least non-message-list) argument handling will
 2132   be changed backward-incompatibly to be sh(1)ell compatible (and
 2133   thus POSIX standardized), see "Shell-style argument quoting"#24.
 2134   New commands use it already today (`bind'#150, `colour'#161,
 2135   `headerpick'#209), some others (most importantly, `set'#269) can
 2136   be forced to do so via the new `wysh'#131 command prefix, as in:
 2137 
 2138     ? wysh set message-inject-tail=$'\n--steffen'
 2139     ? bind base $'\cA,\x61' 'echo control-A and small a'
 2140 
 2141 - We now actively manage *umask*#604: 0077 by default, but an
 2142   empty string will use the setting that is active upon startup.
 2143   Just like changes to (known) environment variables, this setting
 2144   will also be inherited by any child process.
 2145   (Walter Alejandro Iglesias)
 2146 
 2147 - Anything SENDMAIL / *sendmail*-ish has been renamed to *mta*#476,
 2148   *mta-arguments*#478, *mta-no-default-arguments*#479 and
 2149   *mta-argv0*#481.
 2150 
 2151   The reason is that in v15 we won't even have *smtp*: it is just
 2152   another form of MTA, and thus obsolete by itself.
 2153   Note that *mta-arguments* is now parsed via the shell-token
 2154   parser, so the following ends up exactly as desired.
 2155 
 2156     ? set mta-arguments='-t -X "/tmp/my log"'
 2157 
 2158   For now we support a hack that understands a file:// URL in
 2159   *mta*, too, but that is also the default if there is no protocol.
 2160   E.g.: "? set mta=smtp://a:b@xy.z"
 2161 
 2162 - The "spamd" *spam-interface*#570 is obsolete.  I haven't tested
 2163   it since my main machine died, it is error prone since it assumes
 2164   internals of the spamassassin wire protocol, and there never was
 2165   a speed improvement over "spamc".  (However it could react upon
 2166   the "is-spam" state of a message, which "spamc" doesn't allow.)
 2167 
 2168 - The new *inbox*#449 variable will henceforth be looked up when
 2169   searching for a primary system mailbox (as in "? File %"),
 2170   followed by the usual $MAIL#625 and compile-time defined local
 2171   mailspool search.  (Stephen Isard, Jürgen Daubert)
 2172 
 2173 - The semantic of -a#58 and `~@'#318 have been changed, and both
 2174   commands now use the same syntax:
 2175 
 2176     -a file[=input-charset[#output-charset]]
 2177 
 2178 - New "failinvaddr" keyword for *expandaddr*#417.
 2179 
 2180 - We finally "can" the so-called (by myself) "Dr. Problem" (a bit):
 2181   (Dr. Werner Fink)
 2182 
 2183     $ </dev/null s-nail -d:/ -sTrödler 'Dr. D. Iet <z@a.k>' 2>&1 |\
 2184       grep To:
 2185     s-nail: >>> To: "Dr. D. Iet" <z@a.k>
 2186 
 2187   This can be done via the new `addrcodec'#143, too, note this
 2188   supports multiple modes (and the `vput'#130 command modifier):
 2189 
 2190     $ echo 'addrcodec e Dr. Diet <to@fu.soj> Curd' | s-nail -#:/
 2191     "Dr. Diet Curd" <to@fu.soj>
 2192 
 2193 - All commands with the string "codec" in their name use different
 2194   argument quoting, namely none at all, please read
 2195   "Raw data arguments for codec commands"#26.
 2196   This means that `urlcodec'#299 (and `imapcodec'#665) has
 2197   slightly changed semantics.
 2198   And, while here: there is a new `shcodec'#271, too.
 2199 
 2200 - We gained "Command modifiers"#22: `\'#125 (avoid expansion of
 2201   `commandalias'#163es), `vput'#130 (store result in variable),
 2202   `ignerr'#126  (ignore an error of the following command, even
 2203   if the new *errexit*#414 is set), `wysh'#131 (use shell-style
 2204   arguments).
 2205 
 2206     $ echo 'vput cwd resvar;echo $resvar' | s-nail -#:/
 2207     /home/steffen/src/nail.git
 2208 
 2209   And the usual sh(1) stuff: `return'#264, `shift'#275, `eval'#192,
 2210   plus a `xcall'#307 stack-avoidance optimization (to be used in
 2211   place of a `call'#152 which would be the last called command).
 2212   And an "expr(1) like thing", yet simple, `vexpr'#303.
 2213 
 2214     $ echo 'vexpr + 1 2' | s-nail -#:/
 2215     00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000011
 2216     03 | 0x3 | 3
 2217     $ echo 'vput vexpr resvar + 1 2;echo $resvar' | s-nail -#:/
 2218     3
 2219 
 2220   We actually start walking (*?*#348, *^*#350).
 2221 
 2222     ? vput vexpr res regex 'bananarama' 'Bana(.+)' '\$1\$0'
 2223     ? echo $?/$^ERRNAME :$res:
 2224     1/NODATA ::
 2225     ? vput vexpr res iregex 'bananarama' '(.+)rama' '\$1\$0'
 2226     ? echo $?/$^ERRNAME :$res:
 2227     0/NONE :bananabananarama:
 2228 
 2229   The command `vpospar'#304 can be used to manage the stack of
 2230   positional parameters, i.e., much like "set --".
 2231   It also offers the possibility to save and restore the stack to
 2232   and from variables.  Etc.
 2233 
 2234   Btw., to contact the maintainer (make.rc variables
 2235   VAL_CONTACT_WEB and VAL_CONTACT_MAIL):
 2236 
 2237     ? echo $contact-web; eval mail $contact-mail
 2238 
 2239 - `if'#215 no longer performs automatic number conversion, we
 2240   use the explicit -lt, -gt etc. syntax of the sh(1).
 2241   Note: `if' will change to be almost identical to sh(1) if(1),
 2242   so please ensure proper test bracketing, even if it is less
 2243   convenient.
 2244 
 2245   Moreover, the default string comparison mode has changed to
 2246   case-sensitive, just like in the shell.  This is because in the
 2247   future this crux with trigger characters will vanish and `if'
 2248   etc. will simply slurp in already expanded shell tokens, it will
 2249   act like the shell in that respect.  We have modifiers, though,
 2250   yet only "@i" for case-insensitivity, also for regex matches:
 2251 
 2252     LC_ALL=C
 2253     i=`LC_ALL=C.utf8 s-nail -:/ -# -X '
 2254        \define cset_test {
 2255           \if [ "${ttycharset}" @i=% utf ]
 2256              \echo $LC_ALL
 2257              \xit 0
 2258           \end
 2259           \if [ "${#}" -gt 0 ]
 2260              \wysh set LC_ALL=${1}
 2261              \shift
 2262              \eval xcall cset_test "${@}"
 2263           \end
 2264           \xit 1
 2265        }
 2266        \call cset_test C.UTF-8 POSIX.utf8 POSIX.UTF-8 \
 2267           en_EN.utf8 en_EN.UTF-8 en_US.utf8 en_US.UTF-8
 2268    '`
 2269    [ $? -eq 0 ] && UTF8_LOCALE=$i
 2270 
 2271   Please note the `eval' in 'eval xcall cset_test "${@}".  This is
 2272   a difference of S-nail/mailx and the sh(1)ell that will remain,
 2273   as documented in "COMMANDS"#21: whereas the shell implements
 2274   a language and performs standardized expansions on the line
 2275   until finally the command is called, S-nail will decide the type
 2276   of command line parsing dependent on the seen command, and will
 2277   then perform a single expansion.  Therefore "${@}" will expand
 2278   to multiple arguments if $# is greater 0, but it will expand to
 2279   the empty string otherwise, which is not furtherly expanded away
 2280   since it is meaningless like it is in the shell: therefore $#
 2281   will be 1 (the empty string) not 0.
 2282 
 2283 - Using an explicit proto:// prefix should get you the desired
 2284   thing apart of *newfolders*#485, e.g.:
 2285 
 2286     ? File maildir:///tmp/x.mdir
 2287     ? copy * file:///tmp/x.mbox
 2288 
 2289 - New variable *record-files*#530 can be set to extend the meaning
 2290   of *record*#529.  *record-resent*#531 was there already.
 2291 
 2292 - New variable *ifs*#445 acts a bit like the sh(1)ell's $IFS for,
 2293   e.g., the new `read'#251 command.
 2294 
 2295   There is a `readctl'#254 command which can be used to manage
 2296   the active channel used by `read'#251.
 2297 
 2298 - The `~' alias for `call'#152 is gone.
 2299 
 2300 - `mimetype'#225 only allows specification of a single type per
 2301   call, on the other hand no need to quote that.
 2302 
 2303 - `mimeview'#227 must now be used explicitly to look at any
 2304   non-text MIME part, for normal display etc. purposes we only
 2305   support "copiousoutput"#651 MIME handlers.
 2306 
 2307 - New *socks-proxy*#569 can be used to proxy all network traffic
 2308   over a SOCKS5 proxy.  (Gaetan Bisson)
 2309 
 2310 ChangeLog
 2311 ^^^^^^^^^
 2312 
 2313 - The manual has seen another major overhaul, all the variables
 2314   are now documented in a single, sorted list, and many
 2315   clarifications should have been added.  I hope it has become
 2316   a better read.
 2317   (Predrag Punosevac, Michael Convey, Hariskar, Rudolf Sykora,
 2318   Respiranto, Thomas Dickey, Donald Mugnai)
 2319 
 2320 - To support RFC 1524 a.k.a. .mailcap files (see below) many
 2321   "trigger"-characters have been added for *pipe-TYPE/SUBTYPE*#502,
 2322   which may (rarely) affect existing values.
 2323   The .mailcap support itself is not yet implemented.
 2324 
 2325 - *mime-counter-evidence*#472 gained bit 4 (perform proper in-depth
 2326   content inspection as necessary; set to 0xE for all bits).
 2327   (Aharon Robbins)
 2328 
 2329 - Maildir paths are now created recursively as necessary.
 2330   (Justin Ellingwood)
 2331 
 2332 - -M#73 and -m#74 options have been added to enforce a special
 2333   send mode that will flag standard input / the given file with
 2334   the specified / detected MIME 'Content-Type:'.  This can be used
 2335   to directly send, e.g., HTML log output.
 2336   (Viktor Szépe, Ralph Corderoy)
 2337 
 2338 - Disallow symlinks on writable files.  Note this requires
 2339   O_NOFOLLOW support for the operating-system-call open(2), but
 2340   which has been standardized a long time ago.
 2341   (Matthew Dillon)
 2342 
 2343 - `retain'#263, `ignore'#216 etc. now differentiate in between
 2344   From (the From: header) and From_ (the MBOX ident).
 2345 
 2346   In fact we now have a new `headerpick'#209 command which
 2347   is a multiplexer for all retain and ignore lists used, call it
 2348   without arguments to see the current setting(s).
 2349   In v15 only `headerpick' and the standard-imposed wrappers
 2350   `retain' and `ignore' will remain, all other wrappers will
 2351   vanish.  Regular expressions can now be used if available:
 2352 
 2353     ? headerpick
 2354       headerpick type retain blahblahblah cc date from \
 2355         mail-followup-to message-id openpgp reply-to subject to \
 2356         user-agent
 2357       #headerpick type ignore currently covers no fields
 2358       #headerpick save retain currently covers no fields
 2359       headerpick save ignore '^Original-.*$' '^X-.*$' '^DKIM.*$'
 2360       headerpick forward retain cc date from list-id \
 2361         mail-followup-to openpgp reply-to subject to
 2362       #headerpick forward ignore currently covers no fields
 2363 
 2364 - `top'#291 has been rewritten completely, `Top'#290 is new.
 2365   It uses a built-in set of retain/ignore headers, but it is
 2366   possible to register a custom set via `headerpick'#209.
 2367   Also, *toplines*#600 has been extended a bit and the new
 2368   *topsqueeze*#601 variable may pimp your `top' experience.
 2369 
 2370     ? headerpick top retain add subject
 2371     ? top
 2372     [-- Message  1 -- 87 lines, 4791 bytes --]:
 2373     Subject: Re: I can't dist to myself
 2374 
 2375     I wrote:
 2376         3.22. bounce_delivered
 2377 
 2378 - `features' has been dropped, `version'#302 extended.
 2379 
 2380 - The *prompt*#517 handling has changed: we lost the capability to
 2381   expand \?, \@ and \$, instead new "private" variables *?*#348,
 2382   *account*#361, *mailbox-resolved*#459 and
 2383   *mailbox-display*#458 have been introduced, and the prompt
 2384   is completely shell expanded (thus twice with `wysh' or in v15),
 2385   as if dollar-single-quote quoted.  We do support the reverse-
 2386   solidus escaped bracket notation for embedding characters which
 2387   should not be counted when calculating the width of the prompt.
 2388   The `colour'#161 command has a slot for the prompt colour.
 2389   We gained *prompt2*#518 as a second level prompt.
 2390 
 2391     ? var prompt
 2392     wysh set \
 2393       prompt='?\${?}!\${!}[\${account}#\${mailbox-display}]? '
 2394 
 2395 - The filename "-" can be used as a receiver, e.g.,
 2396 
 2397     $ echo Hey,\ you | s-nail -:/ -Sexpandaddr -sUB -
 2398 
 2399 - The -s#81 command line option, the `~s'#340 command escape
 2400   as well as the corresponding slots of `~^'#320 will actively
 2401   strip [\r\n] from their value (Debian #419840).
 2402 
 2403 - New `read'#251 and `echoerr'#183 commands, mostly for
 2404   *on-compose-splice*#492.
 2405   But also `echon'#184 and `echoerrn'#185, which do not write
 2406   a trailing newline.
 2407 
 2408 - New variable *r-option-implicit*#527 may be helpful to those
 2409   who regulary need the functionality of the -r#79 command
 2410   line option.  (Felipe Gasper, Martin Neitzel)
 2411 
 2412 - By using new "pseudo-URLs" one can automatize the use of S/MIME
 2413   keys / (certificates / intermediate include certificates) with
 2414   passwords.  E.g., to drive bob@exam.ple, set
 2415   *smime-sign-cert-bob@exam.ple* to the private key / certificate
 2416   pair as usual, the password lookup will then be performed for
 2417   bob@exam.ple.smime-cert-key, bob@exam.ple.smime-cert-cert and
 2418   bob@exam.ple.smime-include-certs.
 2419   Like this the password can be stored in an encrypted .netrc file
 2420   when *netrc-lookup*#483 and *netrc-pipe*#484 are set, or it may
 2421   be stored in an encrypted resource file that has been loaded via
 2422   `source'#281 as a simple *password*#500 variable.
 2423 
 2424   Note that the prompting that happens as a last resort of
 2425   password lookup will still interfere with a possibly running
 2426   $PAGER#631 instance, dependent on the setting of *crt*#403, of
 2427   course.  Proper job control handling and recognizing that we are
 2428   running $PAGER when doing that prompt is a TODO for v15.  Sorry.
 2429 
 2430 - Some commands, like `set'#269, `help'#212, `list'#217,
 2431   `mlist'#228 etc., now react upon the setting of *verbose*#607
 2432   and(/or) *debug*#407.
 2433 
 2434 - `write'#306 uses iconv(3) as appropriate.
 2435 
 2436 - *mbox-rfc4155*#464 has first been dropped, and was then
 2437   reintroduced with different semantics.  Because, it can be
 2438   helpful if a messed up MBOX is read, in which case we henceforth
 2439   will warn you and point you to this:
 2440 
 2441     ? define mboxfix {
 2442       \localopts yes; \wysh set mbox-rfc4155;\
 2443         \wysh File "${1}"; \eval copy * "${2}"
 2444     }
 2445     ? call mboxfix /tmp/bad.mbox /tmp/good.mbox
 2446 
 2447   P.S.  Here you see how weird the current thing still is, in v15:
 2448 
 2449     ? define mboxfix {
 2450       localopts yes; set mbox-rfc4155; File "${1}"; copy * -- "${2}"
 2451     }
 2452 
 2453   And also in v15 we will not apply (proper) so-called MBOXO
 2454   quoting, but instead (simply MIME) re-encode mail messages.
 2455 
 2456 - `call_if'#153 is new and, different to "? ignerr call", silent
 2457   and not messing with the return status.
 2458 
 2459 - The new *smime-ca-flags*#554 and *ssl-ca-flags*#? can be used
 2460   to fine-tune X509_STORE_set_flags(3) a.k.a the X509 CA
 2461   certificate verification.
 2462 
 2463     ? set ssl-ca-flags=partial-chain
 2464     ? wysh set smime-ca-flags="${ssl-ca-flags}"
 2465 
 2466   Also, *ssl-curves*#? for TLSv1.3.
 2467 
 2468 - Socket connections use TLS S(erver)N(ame)I(ndication) as
 2469   appropriate (RFC 7817).
 2470 
 2471 - `alternates'#146 checks arguments and supports `vput'#130.
 2472   It by default no longer replaces but appends alternates, unless
 2473   *posix*#515 mode is active.  There is a new `unalternates'#147
 2474   command to remove alternates.
 2475 
 2476 - A new `charsetalias'#156 command.  (Pietro Cerutti, mutt#3925)
 2477 
 2478 - New commands `filetype'#196 and `unfiletype'#197: in the future
 2479   we will no longer know any builtin filetypes, in fact we already
 2480   simulate .gz etc. via the new mechanism as necessary:
 2481 
 2482     ? filetype \
 2483        bz2 'bzip2 -dc' 'bzip2 -zc' \
 2484        gpg 'gpg -d' 'gpg -e' \
 2485        gz 'gzip -dc' 'gzip -c' \
 2486        xz 'xz -dc' 'xz -zc' \
 2487        zst 'zstd -dc' 'zstd -19 -zc' \
 2488        zst.pgp 'gpg -d | zstd -dc' 'zstd -19 -zc | gpg -e'
 2489 
 2490 - `~<'#315 now offers a "- [HERE-delimiter]" mode for pasting etc.
 2491   (Ralph Corderoy)
 2492 
 2493 - `exit'#193 and `quit'#250 take an optional exit status.
 2494   (That is not fixated yet, though.)
 2495 
 2496 - We have a useful -h / --help output.  (Doug McIlroy)
 2497 
 2498 - *encoding* obsoleted in favour of new *mime-encoding*#473, which
 2499   now defaults to base64.
 2500 
 2501 - *allnet*#363 now works (broken since nail 10.00, 2002-09-29).
