ncurses-5.4

	  corresponding capability might be
		title=\E]2;%p1%s^G,
	+ modify MKlib_gen.sh to avoid passing "#" tokens through the C
	  preprocessor.  This works around Mac OS X's preprocessor, which
	  insists on adding a blank on each side of the token (report/analysis
	  by Kevin Murphy <[e-mail]>).

20030215
	+ add configure check for wchar_t and wint_t types, rather than rely
	  on preprocessor definitions.  Also work around for gcc fixinclude
	  bug which creates a shadow copy of curses.h if it sees these symbols
	  apparently typedef'd.
	+ if database is disabled, do not generate run_tic.sh
	+ minor fixes for memory-leak checking when termcap is read.

20030208
	+ add checking in tic for incomplete line-drawing character mapping.
	+ update configure script to reflect fix for AC_PROG_GCC_TRADITIONAL,
	  which is broken in autoconf 2.5x for Mac OS X 10.2.3 (report by
	  Gerben Wierda <[e-mail]>).
	+ make return value from _nc_printf_string() consistent.  Before,
	  depending on whether --enable-safe-sprintf was used, it might not be
	  cached for reallocating.

20030201
	+ minor fixes for memory-leak checking in lib_tparm.c, hardscroll.c
	+ correct a potentially-uninitialized value if _read_termtype() does
	  not read as much data as expected (report by Wolfgang Rohdewald
	  <[e-mail]>).
	+ correct several places where the aclocal.m4 macros relied on cache
	  variable names which were incompatible (as usual) between autoconf
	  2.13 and 2.5x, causing the test for broken-linker to give incorrect
	  results (reports by Gerben Wierda <[e-mail]> and Thomas Esser
	  <[e-mail]>).
	+ do not try to open gpm mouse driver if standard output is not a tty;
	  the gpm library does not make this check (from bug report for dialog
	  by David Oliveira <[e-mail]>).

20030125
	+ modified emx.src to correspond more closely to terminfo.src, added
	  emx-base to the latter -TD
	+ add configure option for FreeBSD sysmouse, --with-sysmouse, and
	  implement support for that in lib_mouse.c, lib_getch.c

20030118
	+ revert 20030105 change to can_clear_with(), does not work for the
	  case where the update is made on cells which are blanks with
	  attributes, e.g., reverse.
	+ improve ifdef's to guard against redefinition of wchar_t and wint_t
	  in curses.h (report by Urs Jansen).

20030111
	+ improve mvcur() by checking if it is safe to move when video
	  attributes are set (msgr), and if not, reset/restore attributes
	  within that function rather than doing it separately in the GoTo()
	  function in tty_update.c (suggested by Philippe Blain).
	+ add a message in run_tic.in to explain more clearly what does not
	  work when attempting to create a symbolic link for /usr/lib/terminfo
	  on OS/2 and other platforms with no symbolic links (report by John
	  Polterak).
	+ change several sed scripts to avoid using "\+" since it is not a BRE
	  (basic regular expression).  One instance caused terminfo.5 to be
	  misformatted on FreeBSD (from a FreeBSD bug report by Kazuo Horikawa
	  <[e-mail]>).
	+ correct misspelled 'wint_t' in curs_get_wch.3x (Michael Elkins).

20030105
	+ improve description of terminfo operators, especially static/dynamic
	  variables (comments by Mark I Manning IV <[e-mail]>).
	+ demonstrate use of FIELDTYPE by modifying test/ncurses 'r' test to
	  use the predefined TYPE_ALPHA field-type, and by defining a
	  specialized type for the middle initial/name.
	+ fix MKterminfo.sh, another workaround for POSIXLY_CORRECT misfeature
	  of sed 4.0
	> Philippe Blain:
	+ optimize can_clear_with() a little by testing first if the parameter
	  is indeed a "blank".
	+ simplify ClrBottom() a little by allowing it to use clr_eos to clear
	  sections as small as one line.
	+ improve ClrToEOL() by checking if clr_eos is available before trying
	  to use it.
	+ use tputs() rather than putp() in a few cases in tty_update.c since
	  the corresponding delays are proportional to the number of lines
	  affected: repeat_char, clr_eos, change_scroll_region.

20021231
	+ rewrite of lib_acs.c conflicts with copying of SCREEN acs_map to/from
	  global acs_map[] array; removed the lines that did the copying.

20021228
	+ change some overlooked tputs() calls in scrolling code to use putp()
	  (report by Philippe Blain).
	+ modify lib_getch.c to avoid recursion via wgetnstr() when the input
	  is not a tty and consequently mode-changes do not work (report by
	  <[e-mail]>).
	+ rewrote lib_acs.c to allow PutAttrChar() to decide how to render
	  alternate-characters, i.e., to work with Linux console and UTF-8
	  locale.
	+ correct line/column reference in adjust_window(), needed to make
	  special windows such as curscr track properly when resizing (report
	  by Lucas Gonze <[e-mail]>).
	> Philippe Blain:
	+ correct the value used for blank in ClrBottom() (broken in 20000708).
	+ correct an off-by-one in GoTo() parameter in _nc_scrolln().

20021221
	+ change several tputs() calls in scrolling code to use putp(), to
	  enable padding which may be needed for some terminals (patch by
	  by Philippe Blain).
	+ use '%' as sed substitute delimiter in run_tic script to avoid
	  problems with pathname delimiters such as ':' and '@' (report by John
	  Polterak).
	+ implement a workaround so that line-drawing works with screen's
	  crippled UTF-8 support (tested with 3.9.13).  This only works with
	  the wide-character support (--enable-widec); the normal library will
	  simply suppress line-drawing when running in a UTF-8 locale in screen.

20021214
	+ allow BUILD_CC and related configure script variables to be
	  overridden from the environment.
	+ make build-tools variables in ncurses/Makefile.in consistent with
	  the configure script variables (report by Maciej W Rozycki).
	+ modify ncurses/modules to allow
		configure --disable-leaks --disable-ext-funcs
	  to build (report by Gary Samuelson).
	+ fix a few places in configure.in which lacked quotes (report by
	  Gary Samuelson <[e-mail]>).
	+ correct handling of multibyte characters in waddch_literal() which
	  force wrapping because they are started too late on the line (report
	  by Sam Varshavchik).
	+ small fix for CF_GNAT_VERSION to ignore the help-message which
	  gnatmake adds to its version-message.
	> Maciej W Rozycki <[e-mail]>:
	+ use AC_CHECK_TOOL to get proper values for AR and LD for cross
	  compiling.
	+ use $cross_compiling variable in configure script rather than
	  comparing $host_alias and $target alias, since "host" is
	  traditionally misused in autoconf to refer to the target platform.
	+ change configure --help message to use "build" rather than "host"
	  when referring to the --with-build-XXX options.

20021206
	+ modify CF_GNAT_VERSION to print gnatmake's version, and to allow for
	  possible gnat versions such as 3.2 (report by Chris Lingard
	  <[e-mail]>).
	+ modify #define's for CKILL and other default control characters in
	  tset to use the system's default values if they are defined.
	+ correct interchanged defaults for kill and interrupt characters
	  in tset, which caused it to report unnecessarily (Debian #171583).
	+ repair check for missing C++ compiler, which is broken in autoconf
	  2.5x by hardcoding it to g++ (report by Martin Mokrejs).
	+ update config.guess, config.sub (2002-11-30)
	+ modify configure script to skip --with-shared, etc., when the
	  --with-libtool option is given, since they would be ignored anyway.
	+ fix to allow "configure --with-libtool --with-termlib" to build.
	+ modify configure script to show version number of libtool, to help
	  with bug reports.  libtool still gets confused if the installed
	  ncurses libraries are old, since it ignores the -L options at some
	  point (tested with libtool 1.3.3 and 1.4.3).
	+ reorder configure script's updating of $CPPFLAGS and $CFLAGS to
	  prevent -I options in the user's environment from introducing
	  conflicts with the build -I options (may be related to reports by
	  Patrick Ash and George Goffe).
	+ rename test/define_key.c to test/demo_defkey.c, test/keyok.c to
	  test/demo_keyok.c to allow building these with libtool.

20021123
	+ add example program test/define_key.c for define_key().
	+ add example program test/keyok.c for keyok().
	+ add example program test/ins_wide.c for wins_wch() and wins_wstr().
	+ modify wins_wch() and wins_wstr() to interpret tabs by using the
	  winsch() internal function.
	+ modify setcchar() to allow for wchar_t input strings that have
	  more than one spacing character.

20021116
	+ fix a boundary check in lib_insch.c (patch by Philippe Blain).
	+ change type for *printw functions from NCURSES_CONST to const
	  (prompted by comment by Pedro Palhoto Matos <[e-mail]>,
	  but really from a note on X/Open's website stating that either is
	  acceptable, and the latter will be used in a future revision).
	+ add xterm-1002, xterm-1003 terminfo entries to demonstrate changes in
	  lib_mouse.c (20021026) -TD
	+ add screen-bce, screen-s entries from screen 3.9.13 (report by
	  Adam Lazur <[e-mail]>) -TD
	+ add mterm terminfo entries -TD

20021109
	+ split-out useful fragments in terminfo for vt100 and vt220 numeric
	  keypad, i.e., vt100+keypad, vt100+pfkeys, vt100+fnkeys and
	  vt220+keypad.  The last as embedded in various entries had ka3 and
	  kb2 interchanged (report/discussion with Leonard den Ottolander
	  <[e-mail]>).
	+ add check in tic for keypads consistent with vt100 layout.
	+ improve checks in tic for color capabilities

20021102
	+ check for missing/empty/illegal terminfo name in _nc_read_entry()
	  (report by Martin Mokrejs, where $TERM was set to an empty string).
	+ rewrote lib_insch.c, combining it with lib_insstr.c so both handle
	  tab and other control characters consistently (report by Philippe
	  Blain).
	+ remove an #undef for KEY_EVENT from curses.tail used in the
	  experimental NCURSES_WGETCH_EVENTS feature.  The #undef confuses
	  dpkg's build script (Debian #165897).
	+ fix MKlib_gen.sh, working around the ironically named POSIXLY_CORRECT
	  feature of GNU sed 4.0 (reported by Ervin Nemeth <[e-mail]>).

20021026
	+ implement logic in lib_mouse.c to handle position reports which are
	  generated when XFree86 xterm is initialized with private modes 1002
	  or 1003.  These are returned to the application as the
	  REPORT_MOUSE_POSITION mask, which was not implemented.  Tested both
	  with ncurses 'a' menu (prompted by discussion with Larry Riedel
	  <[e-mail]>).
	+ modify lib_mouse.c to look for "XM" terminfo string, which allows
	  one to override the escape sequence used to enable/disable mouse
	  mode.  In particular this works for XFree86 xterm private modes
	  1002 and 1003.  If "XM" is missing (note that this is an extended
	  name), lib_mouse uses the conventional private mode 1000.
	+ correct NOT_LOCAL() macro in lib_mvcur.c to refer to screen_columns
	  where it used screen_lines (report by Philippe Blain).
	+ correct makefile rules for the case when both --with-libtool and
	  --with-gpm are given (report by Mr E_T <[e-mail]>).
	+ add note to terminfo manpage regarding the differences between
	  setaf/setab and setf/setb capabilities (report by Pavel Roskin).

20021019
	+ remove redundant initialization of TABSIZE in newterm(), since it is
	  already done in setupterm() (report by Philippe Blain).
	+ add test/inserts.c, to test winnstr() and winsch().
	+ replace 'sort' in dist.mk with script that sets locale to POSIX.
	+ update URLs in announce.html.in (patch by Frederic L W Meunier).
	+ remove glibc add-on files, which are no longer needed (report by
	  Frederic L W Meunier).

20021012 5.3 release for upload to ftp.gnu.org
	+ modify ifdef's in etip.h.in to allow the etip.h header to compile
	  with gcc 3.2 (patch by Dimitar Zhekov <[e-mail]>).
	+ add logic to setupterm() to make it like initscr() and newterm(),
	  by checking for $NCURSES_TRACE environment variable and enabling
	  the debug trace in that case.
	+ modify setupterm() to ensure that it initializes the baudrate, for
	  applications such as tput (report by Frank Henigman).
	+ modify definition of bits used for command-line and library debug
	  traces to avoid overlap, using new definition TRACE_SHIFT to relate
	  the two.
	+ document tput's interpretation of parameterized strings according to
	  whether parameters are given, etc. (discussion with Robert De Bath).

20021005 pre-release
	+ correct winnwstr() to account for non-character cells generated when
	  a double-width character is added (report by Michael Bienia
	  <[e-mail]>).
	+ modify _nc_viswbuf2n() to provide better results using wctomb().
	+ correct logic in _nc_varargs() which broke tracing of parameters for
	  formats such as "%.*s".
	+ correct scale factor in linux-c and linux-c-nc terminfo entries
	  (report Floyd Davidson).
	+ change tic -A option to -t, add the same option to infocmp for
	  consistency.
	+ correct "%c" implementation in lib_tparm.c, which did not map a null
	  character to a 128 (cf: 980620) (patch by Frank Henigman
	  <[e-mail]>).

20020928 pre-release
	+ modify MKkey_defs.sh to check for POSIX sort -k option, use that if
	  it is found, to accommodate newer utility which dropped the
	  compatibility support for +number options (reported by Andrey A
	  Chernov).
	+ modify linux terminfo entry to use color palette feature from
	  linux-c-nc entry (comments by Tomasz Wasiak and Floyd Davidson).
	+ restore original color definitions in endwin() if init_color() was
	  used, and resume those colors on the next doupdate() or refresh()
	  (report by Tomasz Wasiak <[e-mail]>).
	+ improve debug-traces by modifying MKlib_gen.sh to generate calls
	  to returnBool() and returnAttr().
