This is a log of changes that ncurses has gone through since Zeyd started
working with Pavel Curtis' original work, pcurses, in 1992.

Changes through 1.9.9e are recorded by Zeyd M Ben-Halim.
Changes since 1.9.9e are recorded by Thomas E Dickey.

Contributors include those who have provided patches (even small ones), as well
as those who provide useful information (bug reports, analyses).  Changes with
no cited author are the work of Thomas E Dickey (TD).

A few contributors are given in this file by their initials.
They each account for one percent or more of the changes since 1.9.9e.
See the AUTHORS file for the corresponding full names.

Changes through 1.9.9e did not credit all contributions;
it is not possible to add this information.

20141206
	+ updated ".map" files so that each symbol that may be shared across
	  the different library configurations has the same label.  Some
	  review is needed to ensure these are really compatible.
	+ modify MKlib_gen.sh to work around change in development version of
	  gcc introduced here:
		  https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.html
		  https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
	  (reports by Marcus Shawcroft, Maohui Lei).
	+ improved configure macro CF_SUBDIR_PATH, from lynx changes.

20141129
	+ improved ".map" files by generating them with a script that builds
	  ncurses with several related configurations and merges the results.
	  A further refinement is planned, to make the tic- and tinfo-library
	  symbols use the same versions across each of the four configurations
	  which are represented (reports by Sven Joachim, Werner Fink).

20141115
	+ improve description of limits for color values and color pairs in
	  curs_color.3x (prompted by patch by Tim van der Molen).
	+ add VERSION file, using first field in that to record the ABI version
	  used for configure --with-libtool --disable-libtool-version
	+ add configure options for applying the ".map" and ".sym" files to
	  the ncurses, form, menu and panel libraries.
	+ add ".map" and ".sym" files to show exported symbols, e.g., for
	  symbol-versioning.

20141101
	+ improve strict compiler-warnings by adding a cast in TRACE_RETURN
	  and making a new TRACE_RETURN1 macro for cases where the cast does
	  not apply.

20141025
	+ in-progress changes to integrate the win32 console driver with the
	  msys2 configuration.

20141018
	+ reviewed terminology 0.6.1, add function key definitions.  None of
	  the vt100-compatibility issues were improved -TD
	+ improve infocmp conversion of extended capabilities to termcap by
	  correcting the limit check against parametrized[], as well as filling
	  in a check if the string happens to have parameters, e.g., "xm"
	  in recent changes.
	+ add check for zero/negative dimensions for resizeterm and resize_term
	  (report by Mike Gran).

20141011
	+ add experimental support for xterm's 1005 mouse mode, to use in a
	  demonstration of its limitations.
	+ add experimental support for "%u" format to terminfo.
	+ modify test/ncurses.c to also show position reports in 'a' test.
	+ minor formatting fixes to _nc_trace_mmask_t, make this function
	  exported to help with debugging mouse changes.
	+ improve behavior of wheel-mice for xterm protocol, noting that there
	  are only button-presses for buttons "4" and "5", so there is no need
	  to wait to combine events into double-clicks (report/analysis by
	  Greg Field).
	+ provide examples xterm-1005 and xterm-1006 terminfo entries -TD
	+ implement decoder for xterm SGR 1006 mouse mode.

20140927
	+ implement curs_set in win_driver.c
	+ implement flash in win_driver.c
	+ fix an infinite loop in win_driver.c if the command-window loses
	  focus.
	+ improve the non-buffered mode, i.e., NCURSES_CONSOLE2, of
	  win_driver.c by temporarily changing the buffer-size to match the
	  window-size to eliminate the scrollback.  Also enforce a minimum
	  screen-size of 24x80 in the non-buffered mode.
	+ modify generated misc/Makefile to suppress install.data from the
	  dependencies if the --disable-db-install option is used, compensating
	  for the top-level makefile changes used to add ncurses*-config in the
	  20140920 changes (report by Steven Honeyman).

20140920
	+ add ncurses*-config to bin-directory of sample package-scripts.
	+ add check to ensure that getopt is available; this is a problem in
	  some older cross-compiler environments.
	+ expanded on the description of --disable-overwrite in INSTALL
	  (prompted by reports by Joakim Tjernlund, Thomas Klausner).
	  See Gentoo #522586 and NetBSD #49200 for examples.
	  which relates to the clarified guidelines.
	+ remove special logic from CF_INCLUDE_DIRS which adds the directory
	  for the --includedir from the build (report by Joakim Tjernlund).
	+ add case for Unixware to CF_XOPEN_SOURCE, from lynx changes.
	+ update config.sub from
		http://git.savannah.gnu.org/cgit/config.git

20140913
	+ add a configure check to ignore some of the plethora of non-working
	  C++ cross-compilers.
	+ build-fixes for Ada95 with gnat 4.9

20140906
	+ build-fix and other improvements for port of ncurses-examples to
	  NetBSD.
	+ minor compiler-warning fixes.

20140831
	+ modify test/demo_termcap.c and test/demo_terminfo.c to make their
	  options more directly comparable, and add "-i" option to specify
	  a terminal description filename to parse for names to lookup.

20140823
	+ fix special case where double-width character overwrites a single-
	  width character in the first column (report by Egmont Koblinger,
	  cf: 20050813).

20140816
	+ fix colors in ncurses 'b' test which did not work after changing
	  it to put the test-strings in subwindows (cf: 20140705).
	+ merge redundant SEE-ALSO sections in form and menu manpages.

20140809
	+ modify declarations for user-data pointers in C++ binding to use
	  reinterpret_cast to facilitate converting typed pointers to void*
	  in user's application (patch by Adam Jiang).
	+ regenerated html manpages.
	+ add note regarding cause and effect for TERM in ncurses manpage,
	  having noted clueless verbiage in Terminal.app's "help" file
	  which reverses cause/effect.
	+ remove special fallback definition for NCURSES_ATTR_T, since macros
	  have resolved type-mismatches using casts (cf: 970412).
	+ fixes for win_driver.c:
	  + handle repainting on endwin/refresh combination.
	  + implement beep().
	  + minor cleanup.

20140802
	+ minor portability fixes for MinGW:
	  + ensure WINVER is defined in makefiles rather than using headers
	  + add check for gnatprep "-T" option
	  + work around bug introduced by gcc 4.8.1 in MinGW which breaks
	    "trace" feature:
	    http://stackoverflow.com/questions/20877689/gcc-4-8-1-minggw-d-option-does-not-work-as-usual
	+ fix most compiler warnings for Cygwin ncurses-examples.
	+ restore "redundant" -I options in test/Makefile.in, since they are
	  typically needed when building the derived ncurses-examples package
	  (cf: 20140726).

20140726
	+ eliminate some redundant -I options used for building libraries, and
	  ensure that ${srcdir} is added to the include-options (prompted by
	  discussion with Paul Gilmartin).
	+ modify configure script to work with Minix3.2
	+ add form library extension O_DYNAMIC_JUSTIFY option which can be
	  used to override the different treatment of justification for static
	  versus dynamic fields (adapted from patch by Leon Winter).
	+ add a null pointer check in test/edit_field.c (report/analysis by
	  Leon Winter, cf: 20130608).

20140719
	+ make workarounds for compiling test-programs with NetBSD curses.
	+ improve configure macro CF_ADD_LIBS, to eliminate repeated -l/-L
	  options, from xterm changes.

20140712
	+ correct Charable() macro check for A_ALTCHARSET in wide-characters.
	+ build-fix for position-debug code in tty_update.c, to work with or
	  without sp-funcs.

20140705
	+ add w/W toggle to ncurses.c 'B' test, to demonstrate permutation of
	  video-attributes and colors with double-width character strings.

20140629
	+ correct check in win_driver.c for saving screen contents, e.g., when
	  NCURSES_CONSOLE2 is set (cf: 20140503).
	+ reorganize b/B menu items in ncurses.c, putting the test-strings into
	  subwindows.  This is needed for a planned change to use Unicode
	  fullwidth characters in the test-screens.
	+ correct update to form status for _NEWTOP, broken by fixes for
	  compiler warnings (patch by Leon Winter, cf: 20120616).

20140621
	+ change shared-library suffix for AIX 5 and 6 to ".so", avoiding
	  conflict with the static library (report by Ben Lentz).
	+ document RPATH_LIST in INSTALLATION file, as part of workarounds for
	  upgrading an ncurses library using the "--with-shared" option.
	+ modify test/ncurses.c c/C tests to cycle through subsets of the
	  total number of colors, to better illustrate 8/16/88/256-colors by
	  providing directly comparable screens.
	+ add test/dots_curses.c, for comparison with the low-level examples.

20140614
	+ fix dereference before null check found by Coverity in tic.c
	  (cf: 20140524).
	+ fix sign-extension bug in read_entry.c which prevented "toe" from
	  reading empty "screen+italics" entry.
	+ modify sgr for screen.xterm-new to support dim capability -TD
	+ add dim capability to nsterm+7 -TD
	+ cancel dim capability for iterm -TD
	+ add dim, invis capabilities to vte-2012 -TD
	+ add sitm/ritm to konsole-base and mlterm3 -TD

20140609
	> fix regression in screen terminfo entries (reports by Christian
	  Ebert, Gabriele Balducci) -TD
	+ revert the change to screen; see notes for why this did not work -TD
	+ cancel sitm/ritm for entries which extend "screen", to work around
	  screen's hardcoded behavior for SGR 3 -TD

20140607
	+ separate masking for sgr in vidputs from sitm/ritm, which do not
	  overlap with sgr functionality.
	+ remove unneeded -i option from adacurses-config; put -a in the -I
	  option for consistency (patch by Pascal Pignard).
	+ update xterm-new to patch #305 -TD
	+ change format of test-scripts for Debian Ada95 and ncurses-examples
	  packages to quilted to work around Debian #700177 (cf: 20130907).
	+ build fix for form_driver_w.c as part of ncurses-examples package for
	  older ncurses than 20131207.
	+ add Hello World example to adacurses-config manpage.
	+ remove unused --enable-pc-files option from Ada95/configure.
	+ add --disable-gnat-projects option for testing.
	+ revert changes to Ada95 project-files configuration (cf: 20140524).
	+ corrected usage message in adacurses-config.

20140524
	+ fix typo in ncurses manpage for the NCURSES_NO_MAGIC_COOKIE
	  environment variable.
	+ improve discussion of input-echoing in curs_getch.3x
	+ clarify discussion in curs_addch.3x of wrapping.
	+ modify parametrized.h to make fln non-padded.
	+ correct several entries which had termcap-style padding used in
	  terminfo: adm21, aj510, alto-h19, att605-pc, x820 -TD
	+ correct syntax for padding in some entries: dg211, h19 -TD
	+ correct ti924-8 which had confused padding versus octal escapes -TD
	+ correct padding in sbi entry -TD
	+ fix an old bug in the termcap emulation; "%i" was ignored in tparm()
	  because the parameters to be incremented were already on the internal
	  stack (report by Corinna Vinschen).
	+ modify tic's "-c" option to take into account the "-C" option to
	  activate additional checks which compare the results from running
	  tparm() on the terminfo expressions versus the translated termcap
	  expressions.
	+ modify tic to allow it to read from FIFOs (report by Matthieu Fronton,
	  cf: 20120324).
	> patches by Nicolas Boulenguez:
	+ explicit dereferences to suppress some style warnings.
	+ when c_varargs_to_ada.c includes its header, use double quotes
	  instead of <>.
	+ samples/ncurses2-util.adb:  removed unused with clause.  The warning
	  was removed by an obsolete pragma.
	+ replaced Unreferenced pragmas with Warnings (Off).  The latter,
	  available with older GNATs, needs no configure test.  This also
	  replaces 3 untested Unreferenced pragmas.
	+ simplified To_C usage in trace handling.  Using two parameters allows
	  some basic formatting, and avoids a warning about security with some
	  compiler flags.
	+ for generated Ada sources, replace many snippets with one pure
	  package.
	+ removed C_Chtype and its conversions.
	+ removed C_AttrType and its conversions.
	+ removed conversions between int, Item_Option_Set, Menu_Option_Set.
	+ removed int, Field_Option_Set, Item_Option_Set conversions.
	+ removed C_TraceType, Attribute_Option_Set conversions.
	+ replaced C.int with direct use of Eti_Error, now enumerated.  As it
	  was used in a case statement, values were tested by the Ada compiler
	  to be consecutive anyway.
	+ src/Makefile.in: remove duplicate stanza
	+ only consider using a project for shared libraries.
	+ style. Silent gnat-4.9 warning about misplaced "then".
	+ generate shared library project to honor ADAFLAGS, LDFLAGS.

20140510
	+ cleanup recently introduced compiler warnings for MingW port.
	+ workaround for ${MAKEFLAGS} configure check versus GNU make 4.0,
	  which introduces more than one gratuitous incompatibility.

20140503
	+ add vt520ansi terminfo entry (patch by Mike Gran)
	+ further improve MinGW support for the scenario where there is an
	  ANSI-escapes handler such as ansicon running in the console window
	  (patch by Juergen Pfeifer).

20140426
	+ add --disable-lib-suffixes option (adapted from patch by Juergen
	  Pfeifer).
	+ merge some changes from Juergen Pfeifer's work with MSYS2, to
	  simplify later merging:
	  + use NC_ISATTY() macro for isatty() in library
	  + add _nc_mingw_isatty() and related functions to windows-driver
	  + rename terminal driver entrypoints to simplify grep's
	+ remove a check in the sp-funcs flavor of newterm() which allowed only
	  the first call to newterm() to succeed (report by Thomas Beierlein,
	  cf: 20090927).

20140419
	+ update config.guess, config.sub from
		http://git.savannah.gnu.org/cgit/config.git

20140412
	+ modify configure script:
	  + drop the -no-gcc option from Intel compiler, from lynx changes.
	  + extend the --with-hashed-db configure option to simplify building
	    with different versions of Berkeley database using FreeBSD ports.
	+ improve initialization for MinGW port (Juergen Pfeifer):
	  + enforce Windows-style path-separator if cross-compiling,
	  + add a driver-name method to each of the drivers,
	  + allow the Windows driver name to match "unknown", ignoring case,
	  + lengthen the built-in name for the Windows console driver to
	    "#win32console", and
	  + move the comparison of driver-names allowing abbreviation, e.g.,
	    to "#win32con" into the Windows console driver.

20140329
	+ add check in tic for mismatch between ccc and initp/initc
	+ cancel ccc in putty-256color and konsole-256color for consistency
	  with the cancelled initc capability (patch by Sven Zuhlsdorf).
	+ add xterm+256setaf building block for various terminals which only
	  get the 256-color feature half-implemented -TD
	+ updated "st" entry (leaving the 0.1.1 version as "simpleterm") to
	  0.4.1 -TD

20140323
	+ fix typo in "mlterm" entry (report by Gabriele Balducci) -TD

20140322
	+ use types from <stdint.h> in sample build-scripts for chtype, etc.
	+ modify configure script and curses.h.in to allow the types specified
	  using --with-chtype and related options to be defined in <stdint.h>
	+ add terminology entry -TD
	+ add mlterm3 entry, use that as "mlterm" -TD
	+ inherit mlterm-256color from mlterm -TD

20140315
	+ modify _nc_New_TopRow_and_CurrentItem() to ensure that the menu's
	  top-row is adjusted as needed to ensure that the current item is
	  on the screen (patch by Johann Klammer).
	+ add wgetdelay() to retrieve _delay member of WINDOW if it happens to
	  be opaque, e.g., in the pthread configuration (prompted by patch by
	  Soren Brinkmann).

20140308
	+ modify ifdef in read_entry.c to handle the case where
	  NCURSES_USE_DATABASE is not defined (patch by Xin Li).
	+ add cast in form_driver_w() to fix ARM build (patch by Xin Li).
	+ add logic to win_driver.c to save/restore screen contents when not
	  allocating a console-buffer (cf: 20140215).

20140301
	+ clarify error-returns from newwin (report by Ruslan Nabioullin).

20140222
	+ fix some compiler warnings in win_driver.c
	+ updated notes for wsvt25 based on tack and vttest -TD
	+ add teken entry to show actual properties of FreeBSD's "xterm"
	  console -TD

20140215
	+ in-progress changes to win_driver.c to implement output without
	  allocating a console-buffer.  This uses a pre-existing environment
	  variable NCGDB used by Juergen Pfeifer for debugging (prompted by
	  discussion with Erwin Waterlander regarding Console2, which hangs
	  when reading in an allocated console-buffer).
	+ add -t option to gdc.c, and modify to accept "S" to step through the
	  scrolling-stages.
	+ regenerate NCURSES-Programming-HOWTO.html to fix some of the broken
	  html emitted by docbook.

20140209
	+ modify CF_XOPEN_SOURCE macro to omit followup check to determine if
	  _XOPEN_SOURCE can/should be defined.  g++ 4.7.2 built on Solaris 10
	  has some header breakage due to its own predefinition of this symbol
	  (report by Jean-Pierre Flori, Sage #15796).

20140201
	+ add/use symbol NCURSES_PAIRS_T like NCURSES_COLOR_T, to illustrate
	  which "short" types are for color pairs and which are color values.
	+ fix build for s390x, by correcting field bit offsets in generated
	  representation clauses when int=32 long=64 and endian=big, or at
	  least on s390x (patch by Nicolas Boulenguez).
	+ minor cleanup change to test/form_driver_w.c (patch by Gaute Hope).

20140125
	+ remove unnecessary ifdef's in Ada95/gen/gen.c, which reportedly do
	  not work as is with gcc 4.8 due to fixes using chtype cast made for
	  new compiler warnings by gcc 4.8 in 20130824 (Debian #735753, patch
	  by Nicolas Boulenguez).

20140118
	+ apply includesubdir variable which was introduced in 20130805 to
	  gen-pkgconfig.in (Debian #735782).

20131221
	+ further improved man2html, used this to fix broken links in html
	  manpages.  See
	  ftp://invisible-island.net/ncurses/patches/man2html

20131214
	+ modify configure-script/ifdef's to allow OLD_TTY feature to be
	  suppressed if the type of ospeed is configured using the option
	  --with-ospeed to not be a short.  By default, it is a short for
	  termcap-compatibility (adapted from suggestion by Christian
	  Weisgerber).
	+ correct a typo in _nc_baudrate() (patch by Christian Weisgerber,
	  cf: 20061230).
	+ fix a few -Wlogical-op warnings.
	+ updated llib-l* files.

20131207
	+ add form_driver_w() entrypoint to wide-character forms library, as
	  well as test program form_driver_w (adapted from patch by Gaute
	  Hope).

20131123
	+ minor fix for CF_GCC_WARNINGS to special-case options which are not
	  recognized by clang.

20131116
	+ add special case to configure script to move _XOPEN_SOURCE_EXTENDED
	  definition from CPPFLAGS to CFLAGS if it happens to be needed for
	  Solaris, because g++ errors with that definition (report by
	  Jean-Pierre Flori, Sage #15268).
	+ correct logic in infocmp's -i option which was intended to ignore
	  strings which correspond to function-keys as candidates for piecing
	  together initialization- or reset-strings.  The problem dates to
	  1.9.7a, but was overlooked until changes in -Wlogical-op warnings for
	  gcc 4.8 (report by David Binderman).
	+ updated CF_GCC_WARNINGS to documented options for gcc 4.9.0, adding
	  checks for -Wextra, -Wignored-qualifiers and -Wlogical-op
	+ updated CF_GCC_WARNINGS to documented options for gcc 4.9.0, moving
	  checks for -Wextra and -Wdeclaration-after-statement into the macro,
	  and adding checks for -Wignored-qualifiers, -Wlogical-op and
	  -Wvarargs
	+ updated CF_CURSES_UNCTRL_H and CF_SHARED_OPTS macros from ongoing
	  work on cdk.
	+ update config.sub from
		http://git.savannah.gnu.org/cgit/config.git

20131110
	+ minor cleanup of terminfo.tail

20131102
	+ use TS extension to describe xterm's title-escapes -TD
	+ modify terminator and nsterm-s to use xterm+sl-twm building block -TD
	+ update hurd.ti, add xenl to reflect 2011-03-06 change in
	  http://git.savannah.gnu.org/cgit/hurd/hurd.git/log/console/display.c
	  (Debian #727119).
	+ simplify pfkey expression in ansi.sys -TD

20131027
	+ correct/simplify ifdef's for cur_term versus broken-linker and
	  reentrant options (report by Jean-Pierre Flori, cf: 20090530).
	+ modify release/version combinations in test build-scripts to make

20130525
	+ modify mvcur() to distinguish between internal use by the ncurses
	  library, and external callers, preventing it from reading the content

	  (Redhat #911540)
	+ update/correct header-dependencies in c++ makefile (report by Werner

	  library.
	+ modify vidattr and vid_attr to use stdout as documented in manpage.
	+ amend changes made to buffering in 20120825 so that the low-level
	  putp() call uses stdout rather than ncurses' internal buffering.
	  The putp_sp() call does the same, for consistency (Redhat #892674).

20130105
	+ add "-s" option to test/view.c to allow it to start in single-step

	  MinGW changes.
	+ revert part of 20121222 change to tinfo_driver.c
	+ add experimental logic in win_driver.c to improve optimization of
	  screen updates.  This does not yet work with double-width characters,

	  regular win32 API because the MinGW functions mblen() and mbtowc()
	  do not work.

20121124
	+ correct order of color initialization versus display in some of the
	  test-programs, e.g., test_addstr.c
