ncurses-5.4

	+ add/use _nc_visbufn() and _nc_viswbufn() to limit the debug trace
	  of waddnstr() and similar functions to match the parameters as used.
	+ add/use _nc_retrace_bool() and _nc_retrace_unsigned().
	+ correct type used by _nc_retrace_chtype().
	+ add debug traces to some functions in lib_mouse.c
	+ modify lib_addch.c to handle non-spacing characters.
	+ correct parameter of RemAttr() in lib_bkgd.c, which caused the c++
	  demo's boxes to lose the A_ALTCHARSET flag (broken in 20020629).
	+ correct width computed in _tracedump(), which did not account for
	  the attributes (broken in 20010602).
	+ modify test/tracemunch to replace addresses for windows other than
	  curscr, newscr and stdscr with window0, window1, etc.

20020921 pre-release
	+ redid fix for edit_man.sed path.
	+ workaround for Cygwin bug which makes subprocess writes to stdout
	  result in core dump.
	+ documented getbegx(), etc.
	+ minor fixes to configure script to use '%' consistently as a sed
	  delimiter rather than '@'.
	> Philippe Blain:
	+ add check in lib_overlay.c to ensure that the windows to be merged
	  actually overlap, and in copywin(), limit the area to be touched
	  to the lines given for the destination window.

20020914 pre-release
	+ modified curses.h so that if the wide-character version is installed
	  overwriting /usr/include/curses.h, and if it relied on libutf8.h,
	  then applications that use that header for wide-character support
	  must define HAVE_LIBUTF8_H.
	+ modify putwin(), getwin() and dupwin() to allow them to operate on
	  pads (request by Philippe Blain).
	+ correct attribute-merging in wborder(), broken in 20020216 (report
	  by Tomasz Wasiak <[e-mail]>).
	> Philippe Blain:
	+ corrected pop-counts in tparam_internal() to '!' and '~' cases.
	+ use sizeof(NCURSES_CH_T) in one place that used sizeof(chtype).
	+ remove some unused variables from mvcur test-driver.

20020907 pre-release
	+ change configure script to allow install of widec-character
	  (ncursesw) headers to overwrite normal (ncurses) headers, since the
	  latter is a compatible subset of the former.
	+ fix path of edit_man.sed in configure script, needed to regenerate
	  html manpages on Debian.
	+ fix mismatched enums in vsscanf.c, which caused warning on Solaris.
	+ update README.emx to reflect current patch used for autoconf.
	+ change web- and ftp-site to invisible-island.net
	> Philippe Blain:
	+ change case for 'P' in tparam_internal() to indicate that it pops
	  a variable from the stack.
	+ correct sense of precision and width in parse_format(), to avoid
	  confusion.
	+ modify lib_tparm.c, absorb really_get_space() into get_space().
	+ modify getwin() and dupwin() to copy the _notimeout, _idlok and
	  _idcok window fields.
	+ better fix for _nc_set_type(), using typeMalloc().

20020901 pre-release
	+ change minor version to 3, i.e., ncurses 5.3
	+ update config.guess, config.sub
	+ retest build with each configure option; minor ifdef fixes.
	+ make keyname() return a null pointer rather than "UNKNOWN STRING" to
	  match XSI.
	+ modify handling of wide line-drawing character functions to use the
	  normal line-drawing characters when not in UTF-8 locale.
	+ add check/fix to comp_parse.c to suppress warning about missing acsc
	  string.  This happens in configurations where raw termcap information
	  is processed; tic already does this and other checks.
	+ modify tic's check for ich/ich1 versus rmir/smir to only warn about
	  ich1, to match xterm patch #70 notes.
	+ moved information for ripped-off lines into SCREEN struct to allow
	  use in resizeterm().
	+ add experimental wgetch_events(), ifdef'd with NCURSES_WGETCH_EVENTS
	  (adapted from patch by Ilya Zakharevich - see ncurses/README.IZ).
	+ amend check in kgetch() from 20020824 to look only for function-keys,
	  otherwise escape sequences are not resolved properly.
	> Philippe Blain:
	+ removed redundant assignment to SP->_checkfd from newterm().
	+ check return-value of setupterm() in restartterm().
	+ use sizeof(NCURSES_CH_T) in a few places that used sizeof(chtype).
	+ prevent dupwin() from duplicating a pad.
	+ prevent putwin() from writing a pad.
	+ use typeRealloc() or typeMalloc() in preference to direct calls on
	  _nc_doalloc().

20020824
	+ add a check in kgetch() for cooked characters in the fifo to avoid
	  calling fifo_push() when a KEY_RESIZE is available (report/analysis
	  by Sam Varshavchik <[e-mail]>).
	+ fix an overlooked case for bugzilla #68199 (Philippe Blain).
	+ ensure clearerr() is called before using ferror() e.g., in
	  lib_screen.c (report by Philippe Blain).

20020817
	+ modify lib_screen.c and lib_newwin.c to maintain the SCREEN-specific
	  pointers for curscr/stdscr/newscr when scr_save() and scr_restore()
	  modify the global curscr/stdscr/newscr variables.  Fixes Redhat
	  bugzilla #68199 dated 2002-07-07.
	+ add checks for null pointer in calls to tparm() and tgoto() based on
	  FreeBSD bug report.  If ncurses were built with termcap support, and
	  the first call to tgoto() were a zero-length string, the result would
	  be a null pointer, which was not handled properly.
	+ correct a typo in terminfo.head, which gave the octal code for colon
	  rather than comma.
	+ remove the "tic -u" option from 20020810, since it did not account
	  for nested "tc=" clauses, and when that was addressed, was still
	  unsatisfactory.

20020810
	+ add tic -A option to suppress capabilities which are commented out
	  when translating to termcap.
	+ add tic -u option to provide older behavior of "tc=" clauses.
	+ modified tic to expand all but the final "tc=" clause in a termcap
	  entry, to accommodate termcap libraries which do not handle multiple
	  tc clauses.
	+ correct typo in curs_inopts.3x regarding CS8/CS7 usage (report by
	  Philippe Blain).
	+ remove a couple of redundant uses of A_ATTRIBUTES in expressions
	  using AttrOf(), which already incorporates that mask (report by
	  Philippe Blain).
	+ document TABSIZE variable.
	+ add NCURSES_ASSUMED_COLORS environment variable, to allow users to
	  override compiled-in default black-on-white assumption used in
	  assume_default_colors().
	+ correct an off-by-one comparison against max_colors in COLORFGBG
	  logic.
	+ correct a use of uninitialized memory found by valgrind (reported by
	  Olaf Buddenhagen <[e-mail]>).
	+ modified wresize() to ensure that a failed realloc will not corrupt
	  the window structure, and to make subwindows fit within the resized
	  window (completes Debian #87678, #101699)

20020803
	+ fix an off-by-one in lib_pad.c check for limits of pad (patch by
	  Philippe Blain).
	+ revise logic for BeOS in lib_twait.c altered in 20011013 to restore
	  logic used by lib_getch.c's support for GPM or EMX mouse (report by
	  Philippe Blain)
	+ remove NCURSES_CONST from several prototypes in curses.wide, to make
	  the --enable-const --enable-widec configure options to work together
	  (report by George Goffe <[e-mail]>).

20020727
	+ finish no-leak checking in cardfile.c, using this for testing changes
	  to resizeterm().
	+ simplify _nc_freeall() using delscreen().

20020720
	+ check error-return from _nc_set_tty_mode() in _nc_initscr() and
	  reset_prog_mode() (report/patch by Philippe Blain).
	+ regenerate configure using patch for autoconf 2.52, to address
	  problem with identifying C++ bool type.
	+ correct/improve logic to produce an exit status for errors in tput,
	  which did not exit with an error when told to put a string not in the
	  current terminfo entry (report by David Gomez <[e-mail]>).
	+ modify configure script AC_OUTPUT() call to work around defect in
	  autoconf 2.52 which adds an ifdef'd include to the generated
	  configure definitions.
	+ remove fstat() check from scr_init(), which also fixes a missing
	  include for <sys/stat.h> from 20020713 (reported by David Ellement,
	  fix suggested by Philippe Blain).
	+ update curs_scanw.3x manpage to note that XSI curses differs from
	  SVr4 curses: return-values are incompatible.
	+ correct several prototypes in manpages which used const
	  inconsistently with the curses.h file, and removed spurious const's
	  in a few places from curses.h, e.g., for wbkgd() (report by Glenn
	  Maynard <[e-mail]>).
	+ change internal type used by tparm() to long, to work with LP64 model.
	+ modify nc_alloc.h to allow building with g++, for testing.

20020713
	+ add resize-handling to cardfile.c test program.
	+ altered resizeterm() to avoid having it fail when a child window
	  cannot be resized because it would be larger than its parent.  (More
	  work must be done on this, but it works well enough to integrate).
	+ improve a limit-check in lib_refresh.c
	+ remove check in lib_screen.c relating dumptime to file's modification
	  times, since that would not necessarily work for remotely mounted
	  filesystems.
	+ modify lrtest to simplify debugging changes to resizeterm, e.g.,
	  t/T commands to enable/disable tracing.
	+ updated status of multibyte support in TO-DO.
	+ update contact info in source-files (patch by Juergen Pfeifer).

20020706
	+ add Caps.hpux11, as an example.
	+ modify version_filter(), used to implement -R option for tic and
	  infocmp, to use computed array offsets based on the Caps.* file which
	  is actually configured, rather than constants which correspond to
	  the Caps file.
	+ reorganized lib_raw.c to avoid updating SP and cur_term state if the
	  functions fail (reported by Philippe Blain).
	+ add -Wundef to gcc warnings, adjust a few ifdef's to accommodate gcc.

20020629
	+ correct parameters to setcchar() in ncurses.c (cf: 20020406).
	+ set locale in most test programs (view.c and ncurses.c were the
	  only ones).
	+ add configure option --with-build-cppflags (report by Maksim A
	  Nikulin <[e-mail]>).
	+ correct a typo in wide-character logic for lib_bkgnd.c (Philippe
	  Blain).
	+ modify lib_wacs.c to not cancel the acsc, smacs, rmacs strings when
	  in UTF-8 locale.  Wide-character functions use Unicode values, while
	  narrow-character functions use the terminfo data.
	+ fix a couple of places in Ada95/samples which did not compile with
	  gnat 3.14
	+ modify mkinstalldirs so the DOS-pathname case is locale-independent.
	+ fix locale problem in MKlib_gen.sh by forcing related variables to
	  POSIX (C), using same approach as autoconf (set variables only if
	  they were set before).  Update MKterminfo.sh and MKtermsort.sh to
	  match.

20020622
	+ add charset to generated html.
	+ add mvterm entry, adapted from a FreeBSD bug-report by Daniel Rudy
	  <[e-mail]> -TD
	+ add rxvt-16color, ibm+16color entries -TD
	+ modify check in --disable-overwrite option so that it is used by
	  default unless the --prefix/$prefix value is not /usr, in attempt to
	  work around packagers, e.g., for Sun's freeware, who do not read the
	  INSTALL notes.

20020615
	+ modify wgetch() to allow returning ungetch'd KEY_RESIZE as a function
	  key code in get_wch().
	+ extended resize-handling in test/ncurses 'a' menu to the entire
	  stack of windows created with 'w' commands.
	+ improve $COLORFGBG feature by interpreting an out-of-range color
	  value as an SGR 39 or 49, for foreground/background respectively.
	+ correct a typo in configure --enable-colorfgbg option, and move it
	  to the experimental section (cf: 20011208).

20020601
	+ add logic to dump_entry.c to remove function-key definitions that do
	  not fit into the 1023-byte limit for generated termcaps.  This makes
	  hds200 fit.
	+ more improvements to tic's warnings, including logic to ignore
	  differences between delay values in sgr strings.
	+ move definition of KEY_RESIZE into MKkeydefs.sh script, to
	  accommodate Caps.osf1r5 which introduced a conflicting definition.

20020525
	+ add simple resize-handling in test/ncurses.c 'a' menu.
	+ fixes in keyname() and _tracechar() to handle negative values.
	+ make tic's warnings about mismatches in sgr strings easier to follow.
	+ correct tic checks for number of parameters in smgbp and smglp.
	+ improve scoansi terminfo entry, and add scoansi-new entry -TD
	+ add pcvt25-color terminfo entry -TD
	+ add kf13-kf48 strings to cons25w terminfo entry (reported by Stephen
	  Hurd <[e-mail]> in newsgroup lucky.freebsd.bugs) -TD
	+ add entrypoint _nc_trace_ttymode(), use this to distinguish the
	  Ottyb and Nttyb members of terminal (aka cur_term), for tracing.

20020523
	+ correct and simplify logic for lib_pad.c change in 20020518 (reported
	  by Mike Castle).

20020518
	+ fix lib_pad.c for case of drawing a double-width character which
	  falls off the left margin of the pad (patch by Kriang Lerdsuwanakij
	  <[e-mail]>)
	+ modify configure script to work around broken gcc 3.1 "--version"
	  option, which adds unnecessary trash to the requested information.
	+ adjust ifdef's in case SIGWINCH is not defined, e.g., with DJGPP
	  (reported by Ben Decker <[e-mail]>).

20020511
	+ implement vid_puts(), vid_attr(), term_attrs() based on the narrow-
	  character versions as well.
	+ implement erasewchar(), killwchar() based on erasechar() and
	  killchar().
	+ modify erasechar() and killchar() to return ERR if the value was
	  VDISABLE.
	+ correct a bug in wresize() in handling subwindows (based on patch by
	  Roger Gammans <[e-mail]>, report by Scott Beck
