Changelog:
Changes since 5.0.0
-------------------
Numeric constants encountered in mathematical expressions (but not other
contexts) can contain underscores as separators that will be ignored on
evaluation, as allowed in other scripting languages. For example,
0xFFFF_FFFF, or 3.141_592_654.
"functions -T" turns on tracing for the specified function(s) only,
similar to "functions -t" except that tracing is turned off for any
functions called from the specified one(s) that don't also have the -t
or -T flag.
In file completion, the recursive-files style can be set to an array of
patterns to match against "$PWD/". In any matched location, it is
possibly to complete files in arbitrarily deep subdirectories without
needing to type the directory prefix. See example in the zshcompsys
manual.
The _user_expand completer now allows expansion functions in the
user-expand files to return a string in REPLY that will be used to name
the set of expansions returned.
Adam Hoka and hugor.
fish is a user friendly command line shell for UNIX-like operating
systems, written mainly with interactive use in mind. It differs
from other shells in that it only provides as few commands as
built-ins as possible and has a daemon which allows it to have
shared variables and command-line history between shell instances.
It also features feature-rich tab-completion and has command-line
syntax highlighting.

don't read-uninitialized for \177 in a here-doc
A DEL (0177, dec 127) byte in a here-document would cause dash to
access uninitialized memory at the end of one of the syntax.c
tables,
since those tables are sized to accommodate a maximum index of
BASESYNTAX + 126. Make the generated tables one byte larger.
printf ':<<\\E\n\200y\nE'|./dash
* src/mksyntax.c (filltable): Use 258, not 257 as the size,
so that BASESYNTAX(=130) + 127 is a valid index.
(print): Likewise.
Don't emit explicit array dimension in declaration.
* Avoid compiler warnings on isdigit.
* Add another missing LC_COLLATE to mkbuiltins.
* Fix NUL termination in readcmd.
* Lookup PWD after going through CDPATH.
* Pass EV_TESTED into evalcmd.
* Revert SKIPEVAL into EXEXIT.
* Add preliminary LINENO support.
* Honor tab as IFS whitespace when splitting fields in readcmd.
* Do not truncate file for FROMTO redirection.
* Fix quoted pattern patch breakage.
* Fix incorrect savefd conversions.
* Fix dowait signal race.
* Remove EXSIG.
* Do not close stderr when /dev/tty fails to open.
* Allow newlines after var name in for statements.
* Use CHKNL to parse case statements.
* Update manual page to differentiate dash from ash.
a window when the new patch file wasn't committed, and there's no check
for "extra" lines in distinfo, so this clearly identifies the version
with the new patch file included.
This unbreaks at least one of AST/ksh packages.

This source and binary release contains minor fixes to the
unannounced 2010-02-02 release. It is the first official
non-beta release in almost 8 months (we really do try to
decrease the time between official releases, but the
abundance of moving targets sometimes makes that
interesting). See the release change log for details:

2009-05-05
This source and binary release cleans up a few reported
build problems in the 2009-05-01 release (which has been
removed). The release procedures have been adjusted to avoid
similar problems in the future. (The main problem is
synthesizing external non-ast environments to fully exercise
portions of the build system seen by outside users -- since
we use our stuff for everything, including packaging and
building, setting up an environment that has no ast
components leaking in can be non-trivial).
See the release change log for details:
http://www2.research.att.com/~gsf/download/release.2009-05-05.2009-05-01.html
2009-05-01
This source release contains the official (and hopefully
final) ksh93t+ 2009-05-01, along with updates for the ast
commands and libraries. A lot of work went into cleaning up
the regression tests -- most regressions directly correspond
to unsupported native system features or buggy native system
interfaces that we felt should be fixed rather than worked around.
Of course we could be persuaded otherwise.

2007-03-28
Yes -- a new release in only 3 months. This release contains
fixes and features that address the issues raised on the lists.
A summary of recent ksh93 changes:
1. Double precision floating point arithmetic with full C99
arithmetic support on systems that provide the C99
arithmetic functions. The numbers Inf and NaN can be
used in arithmetic expressions.
2. TAB-TAB completion generates a numbered list of
completions which the user can select.
3. Support for processing/handling multibyte locales (e.g.,
en_US.UTF-8, hi_IN.UTF-8, ja_JP.eucJP, zh_CN.GB18030,
zh_TW.BIG5 etc.) has been extensively revised, tested,
and is now supported even on the language level (e.g.
variable and function identifiers may contain locale
specific codeset characters).
4. /dev/(tcp|udp|sctp)/host/sevrice now handles IPv6
addresses on systems that provide getaddrinfo(3).
5. The ability to seek on a file by offset or content with
new redirection operators.
6. A new --showme option which allows portions of a script
to behave as if -x were specified while other parts
execute as usual. This simplifies the coding of make -n
style semantics at the script level by eliminating code
replication. In particular, io redirections are handled
by --showme.
7. The [[...]] operator =~ has been added which compares
the string to an extended regular expression rather than
== which compares against a shell pattern.
8. The printf(1) builtin has been extended to support the =
flag for centering a field. The # flag when used with
%d and %i provides values in units of thousands or 1024
respectively with an appropriate suffix added.
9. Example screenshots from joint work with the Solaris
ksh93 integration project are available here.

This release, almost a year from the last big release,
contains changes based on feedback from the { ast-users
ast-developers uwin-users uwin-developers } lists and the
ongoing ksh93-solaris integration project. Thanks to all
who helped. Our resolution this year is to increase release
frequency to keep internal and external source/binaries
more in sync. See the release change log for details:

This package will install tcsh in the /bin directory (not ${LOCALBASE}/bin).
DragonFly already has tcsh in the base system, so this package will replace
it with no ability to restore the system version. This is not desired.
shells/tcsh still works should there be any need for a pkgsrc version installed
at ${LOCALBASE}/bin.
mksh R40f fixes a critical bug as well as this:
[tg, RT] Implement fcntl(2)-based advisory locking as an alternative
iff flock(2) is not found (LP: #912691); keep trying in the face of EINTR
[tg] Fix severe regression wrt. initialising tty(4) states
[tg] Improve testsuite, build-time checks and debugging output
[tg, RT, winstonw] Improve portability to BeOS (works), Cygwin (good),
Dell UNIX (works somewhat, but not with gcc), LynxOS (works somewhat),
NeXTstep (works but not OpenStep 4.2), USL C compiler, SCO OpenServer (good),
SCO UnixWare (good), Plan 9 (still broken), Syllable Desktop (broken?)
[tg] rlim_t is supposed to be unsigned
[tg] Some code, warning and spelling cleanup
[tg] New Build.sh environment configurable: AWK (= awk)
[tg, DONG-DONG YANG] Add safety net in the Emacs line editing code
[tg] No longer rely on env(1), id(1), printf(1) in the testsuite, and
strcasecmp(3), strcasestr(3), strncasecmp(3) in the code
[tg, stsc, RT] Reduce system requirements of check.pl further
mksh R40e is another must-have bugfix update:
[tg, Jilles Tjoelker] skip readonly check in unevaluated ternary twig
[tg, anonymous] fix all remaining ifs.sh testcases
[tg] No longer try to build with GCC and C99 extensions
[tg, Jilles Tjoelker] Do not expand aliases in COMSUB twice
[tg] Honour UTF-8 multi-byte character boundaries when doing partial
tab-completion insertions (LP: #909025) to fix RedHat BZ#745702
[tg] Fix R40 (BZ#496791) regression with IOACT in TIF (LP: #907224)
[tg, ft] Darn persistent history code worst offenders (LP: #906914)
[tg] Fix some gc-sections, GCC and Clang/scan-build warnings/issues
[tg, 28C3] dot.mkshrc hash functions: partially address LP: #909818
[tg] Only compile divmod(0x80000000, -1) code in when not unneeded
[tg, RT] Move mirtoconf checks and INCLUDES_ONLY parts of
sh.h around to ensure prerequisites are always available
[tg, RT, ir0nh34d] Pass mksh.exe to testsuite, if such thing is generated,
and deal with Cygwin passing just "mksh" in argv[0] in such cases
[tg] Imply -DMKSH_ASSUME_UTF8=0 on MSYS; optimise checks
[tg, Jb_boin] Fix regression introduced in R35b by jaredy's security
patch where TTIME trashed a non-TCOM string argument (e.g. in TFOR)
[tg] Better support for tcc; fix GCCism that accidentally crept in
[tg] Deal with UTF-8 when reporting jobs' commands
[RT] Add SkyOS to known OS list
[tg, RT] Support Minix in its variants Minix 3 and Ninix 3 better
[tg] Drop some Android-specific unused code (lsmod builtin)
[tg, RT, lewellyn] Support QNX and various versions of BSD/OS better
[tg] More code cleanup and new developer-only debugging functions
[tg, Andrew Kudryashov] Fix some tab completion related escaping bugs
[tg, draenog] Honour COLUMNS and LINES from the environment in scripts
[tg, winstonw] The sleep built-in utility now blocks more signals
[tg] Warn when using another deprecated function that will be removed
