Changes through 1.9.9e did not credit all contributions;
it is not possible to add this information.
+20190202
+ + modify rpm test-package ".spec" file to work around naming conflict
+ with Redhat's package for ncurses6.
+ + modify no-leaks code in test/picsmap to avoid non-standard tdestroy.
+ + amend change to configure script which altered the top-level makefile
+ to avoid attempting to install the terminfo database when it was not
+ configured, to allow for installing the ".pc" files which are also
+ in the misc directory (report by Steve Wills).
+
+20190126
+ + change some "%define" statements in test-packages for RPMs to
+ "%global" to work around changes in rpm 4.14 from recent Redhat.
+ + fixes for O_INPUT_FIELD extension (patch by Leon Winter).
+ + eliminate fixed buffer-size when reading $TERMCAP variable.
+ + correct logic in read_entry.c which prevented $TERMCAP variable from
+ being interpreted as a fallback to terminfo entry (prompted by
+ Savannah #54556, cf: 20110924).
+
+20190121
+ + add a check in test/configure to work around non-ncurses termcap.h
+ file in Slackware.
+ + corrected flag for "seq" method of db 1.8.5 interface, needed by toe
+ on some of the BSDs.
+ + updated "string-hacks" feature.
+ + minor improvements to manpage typography.
+ + corrected conditionally-compiled limit on color pairs (report by
+ "Hudd").
+ + add -x option to test/pair_content, test/color_content for testing
+ init_extended_pair, extended_pair_content, init_extended_color,
+ extended_color_content
+ + add -p option to test/pair_content, test/color_content to show the
+ return values from the tested functions.
+ + improve manual page curs_color.3x discussion of error returns and
+ extensions.
+ + add O_INPUT_FIELD extension to form library (patch by Leon Winter).
+ + override/suppress --enable-db-install if --disable-database configure
+ option was given.

+
+20190105
+ + add dummy "check" rule in top-level and test-Makefile to simply
+ building test-packages for Arch.
+ + modify configure script to avoid conflict with a non-POSIX feature
+ that enables all parts of the system headers by default. Some
+ packagers have come to rely upon this behavior (FreeBSD #234049).
+ + update config.guess, config.sub
+
+20181229
+ + improve man/curs_mouse.3x with regard to xterm
+ + modify tracemunch to accept filename parameters in addition to use

+ names.
+
+20181215
+ + several fixes for gcc8 strict compiler warnings.
+ + fix a typo in comments (Aaron Gyes).
+ + add nsterm-build309 to replace nsterm-256color, assigning the latter

+ + updates for configure macros from work on tin and xterm:
+ + CF_GNU_SOURCE, allow for Cygwin's newlib when checking for the
+ _DEFAULT_SOURCE symbol.
+ + CF_VA_COPY, add fallback check if neither va_copy/__va_copy is
+ supported, to try copying the pointers for va_list, or as an array.
+ Also add another fallback check, for __builtin_va_copy(), which
+ could be used with AIX xlc in c89 mode.
+
+20181208
+ + modify wbkgd() and wbkgrnd() to improve compatibility with SVr4
+ curses, changing the way the window rendition is updated when the
+ background character is modified (report by Valery Ushakov).
+
+20181201
+ + add midnightbsd to CF_XOPEN_SOURCE macro (patch by Urs Jansen).
+ + add "@" command to test/ncurses F-test, to allow rapid jump to

+ the fallback information to top-level Makefile summary.
+ + add some traces in initialization to show whether a fallback entry is
+ used.
+ + build-fix for test/movewindow with ncurses-examples on Solaris.
+ + add "-l" option to test/background, to dump screen contents in a form
+ that lets different curses implementations be compared.
+ + modify the initialization checks for mouse so that the xterm+sm+1006
+ block will work with terminal descriptions not mentioning xterm
+ (report by Tomas Janousek).
+
+20181117
+ + ignore the hex/b64 $TERMINFO in toe's listing.
+ + correct a status-check in _nc_read_tic_entry() so that if reading
+ a hex/b64 $TERMINFO, and the $TERM does not match, fall-through to
+ the compiled-in search list.
+
+20181110
+ + several workarounds to ensure proper C compiler used in parts of
+ Ada95 tree.
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20181027
+ + add OpenGL clients alacritty and kitty -TD
+ + add Smulx for tmux, vte-2018 -Nicholas Marriott
+
+20181020
+ + ignore $TERMINFO as a default value in configure script if it came
+ from the infocmp -Q option.
+ + allow value for --with-versioned-syms to be a relative pathname
+ + add a couple of broken-linker symbols to the list of versioned
+ symbols to help with link-time optimization versus weak symbols.
+ + apply shift/control/alt logic when decoding xterm's 1006 mode to
+ wheel-mouse events (Redhat #1610681).
+
+20181013
+ + amend change from 20180818, which undid a fix for the $INSTALL value
+ to make it an absolute path.
+
+20181006

+20180922
+ + ignore interrupted system-call in test/ncurses's command-line, e.g.,
+ if the terminal were resized.
+ + add shift/control/alt logic for decoding xterm's 1006 mode (Redhat
+ #1610681, cf: 20141011).
+ + modify rpm test-packages to not use --disable-relink with Redhat,
+ since Fedora 28's tools do not work with that feature.
+
+20180908
+ + document --with-pcre2 configure option in INSTALL.
+ + improve workaround for special case in PutAttrChar() where a cell is
+ marked as alternate-character set, to handle a case where the
+ character in the cell does not correspond to any of the ASCII
+ fallbacks (report by Leon Winter, cf: 20180505).
+ + amend change to form library which attempted to avoid unnecessary
+ update of cursor position in non-public fields, to simply disable
+ output in this case (patch by Leon Winter, cf: 20180414).
+ + improve check for LINE_MAX runtime limit, to accommodate broken
+ implementations of sysconf().
+

+ terminal size (prompted by discussion with Grant Jenks).
+ + add "--disable-relink" to rpm test-packages, for consistency with the
+ deb test-packages.
+ + split spec-file into ncurses6.spec and ncursest6.spec to work around
+ toolset breakage in Fedora 28.
+ + drop mention of "--disable-touching", which was not in the final
+ 20180818 updates.
+
+20180818
+ + build-fix for PDCurses with ncurses-examples.
+ + improved CF_CC_ENV_FLAGS.
+ + modify configure scripts to reduce relinking/ranlib during library
+ install (Debian #903790):
+ + use "install -p" when available, to avoid need for ranlib of
+ static libraries.
+ + modify scripts which use "--disable-relink" to add a 1-second
+ sleep to work around tools which use whole-second timestamps, e.g.,
+ in utime() rather than the actual file system resolution.
+
+20180804
+ + improve logic for clear with E3 extension, in case the terminal
+ scrolls content onto its saved-lines before actually clearing
+ the display, by clearing the saved-lines after clearing the
+ display (report/patch by Nicholas Marriott).

+ + add acsc string to vi200 (Nibby Nebbulous)
+ add right/down-arrow to vi200's acsc -TD
+ + add "x" to tput's getopt string so that "tput -x clear" works

+ + add "#error" in a few places to flag unsupported configurations
+
+20180623
+ + use _WIN32/_WIN64 in preference to __MINGW32__/__MINGW64__ symbols
+ to simplify building with MSVC, since the former are defined in both
+ compiler configurations (report by Ali Abdulkadir).
+ + further improvements to configure-checks from work on dialog, i.e.,

+ use of vsscanf and setenv.
+ + improved configure-checks CF_SIZECHANGE and CF_STRUCT_TERMIOS from
+ work on dialog.
+
+20180609
+ + modify generated ncurses*config and ncurses.pc, ncursesw.pc, etc.,
+ to list helper libraries such as gpm for static linking (Debian
+ #900839).
+ + marked vwprintw and vwscanw as deprecated; recommend using vw_printw
+ and vw_scanw, respectively.
+
+20180602
+ + add RPM test-package "ncursest-examples".
+ + modified RPM test-package to work with Mageia6.
+
+20180526
+ + add note in curs_util.3x about unctrl.h
+ + review/improve header files to ensure that those include necessary
+ files except for the previously-documented cases (report by Isaac
+ Pascual Monells).
+ + improved test-package scripts, adapted from byacc 1.9 20180525.
+ + fix some gcc8 warnings seen in Redhat package build, but
+ work around bug in gcc8 compiler warnings in comp_parse.c
+
+20180519
+ + formatting fixes for manpages, regenerate man-html documentation.

+ the given graphic character. This would happen in an older terminal
+ such as vt52, which lacks most line-drawing capability.
+ + use configure --with-config-suffix option to work around filename
+ conflict with Debian packages versus test-packages.
+ + update tracemunch to work with perl 5.26.2, which changed the rules
+ for escaping regular expressions.
+
+20180428
+ + document new form-extension O_EDGE_INSERT_STAY (report by Leon
+ Winter).
+ + correct error-returns listed in manual pages for a few form functions
+ (report by Leon Winter).
+ + add a check in form-library for null-pointer dereference:
+ unfocus_current_field (form);
+ form_driver (form, REQ_VALIDATION);
+ (patch by Leon Winter).
+
+20180414
+ + modify form library to optionally delay cursor movement on a field
+ edge/boundary (patch by Leon Winter).

+
+20180407
+ + clarify in manual pages that vwprintw and vwscanw are obsolete,
+ not part of X/Open Curses since 2007.
+ + use "const" in some prototypes rather than NCURSES_CONST where X/Open
+ Curses was updated to do this, e.g., wscanw, newterm, the terminfo
+ interface. Also use "const" for consistency in the termcap
+ interface, which was withdrawn by X/Open Curses in Issue 5 (2007).
+ As of Issue 7, X/Open Curses still lacks "const" for certain return
+ values, e.g., keyname().
+
+20180331
+ + improve terminfo write/read by modifying the fourth item of the
+ extended header to denote the number of valid strings in the extended
+ string table (prompted by a comment in unibilium's sources).
+
+20180324
+ + amend Scaled256() macro in test/picsmap.c to cover the full range
+ 0..1000 (report by Roger Pau Monne).
+ + add some checks in tracemunch for undefined variables.
+ + trim some redundant capabilities from st-0.7 -TD
+ + trim unnecessary setf/setb from interix -TD
+
+20180317
+ + fix a check in infotocap which may not have detected a problem when
+ it should have.
+ + add a check in tic for the case where setf/setb are given using
+ different strings, but provide identical results to setaf/setab.
+ + further improve fix for terminfo.5 (patch by Kir Kolyshkin).
+ + reorder loop-limit checks in winsnstr() in case the string has no
+ terminating null and only the number of characters is used (patch
+ by Gyorgy Jeney).
+
+20180303
+ + modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
+ avoid expansion of "CUR" in trace.
+ + improve a few lintian warnings in test-packages.
+ + modify lib_setup to avoid calling pthread_self() without first
+ verifying that the address is valid, i.e., for weak symbols
+ (report/patch by Werner Fink).
+ + modify generated terminfo.5 to not use "expand" and related width
+ on the last column of tables, making layout on wide terminals look
+ better (adapted from patch by Kir Kolyshkin).
+ + add a category to report_offsets, e.g., "w" for wide-character, "t"
+ for threads to make the report more readable. Reorganized the
+ structures reported to make the categories more apparent.
+ + simplify some ifdef's for extended-colors.
+ + add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
+ how similar the different tinfo configurations are.
+
+20180224
+ + modify _nc_resolve_uses2() to detect incompatible types when merging
+ a "use=" clause of extended capabilities. The problem was seen in a
+ defective terminfo integrated from simpleterm sources in 20171111,
+ compounded by repair in 20180121.
+ + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+ + fix remaining flash capabilities with trailing mandatory delays -TD
+ + correct cut/paste in NEWS (report by Sven Joachim).
+
+20180217
+ + remove incorrect free() from 20170617 changes (report by David Macek).
+ + correct type for "U8" in user_caps.5; it is a number not boolean.
+ + add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
+ + improve fix for Debian #882620 by reusing limit2 variable (report by
+ Julien Cristau, Sven Joachim).
+
+20180210
+ + modify misc/Makefile.in to install/uninstall explicit list in case
+ the build-directory happens to have no ".pc" files when an uninstall
+ is performed (report by Jeffrey Walton).
+ + deprecate safe-sprintf, since the vsnprintf function, which does what
+ was needed, was standardized long ago.
+ + add several development/experimental options to development packages.
+ + minor reordering of options in configure script to make the threaded
+ and reentrant options distinct from the other extensions which are
+ normally enabled.
+
+20180203
+ + minor fixes to test/*.h to make them idempotent.
+ + add/use test/parse_rgb.h to show how the "RGB" capability works.
+ + add a clarification in user_caps.5 regarding "RGB" capability.
+ + add extended_slk_color{,_sp} symbols to the appropriate
+ package/*.{map,sym} files (report by Sven Joachim, cf: 20170401).

+ > merge branch begun April 2, 2017 which provides these features:
+ + support read/write new binary-format for terminfo which stores
+ numeric capabilities as a signed 32-bit integer. The test programs
+ such as picsmap, ncurses were created or updated during 2017 to use
+ this feature.
+ + the new format is written by the wide-character configuration of
+ tic when it finds a numeric capability larger than 32767.
+ + other applications such as infocmp built with the wide-character
+ ncurses library work as expected.
+ + applications built with the "narrow" (8-bit) configuration will
+ read the new format, but will limit those extended values to 32767.
+ + in either wide/narrow configuration, the structure defined in
+ term.h still uses signed 16-bit values.
+ + because it is incompatible with the legacy (mid-1980s) binary format,
+ a new magic value is provided for the "file" program.
+ + the term.5 manual page is updated to describe this new format.
+ + the limit on file-size for compiled terminfo is increased in the
+ wide-character configuration to 32768.
+
+20180120
+ + build-fix in picsmap.c for stdint.h existence.
+ + add --disable-stripping option to configure scripts.
+ + modify ncurses-examples to install test-scripts in the data directory.
+ + work around tool-breakage in Debian 9 and later by invoking
+ gprconfig to specify the C compiler to be used by gnatmake,
+ and conditionally suppressing Library_Options line for static
+ libraries.
+ + bump the compat level for test-packages to 7, i.e., Debian 5.
+
+20180106
+ + fixes for writing extended color pairs in putwin.
+ + modify test/savescreen.c to add test patterns that exercise 88-,
+ 256-, etc., colors.
+ + modify configure option --with-build-cc, adding clang, c89 and c99
+ as possible default values.
+ + modify ncurses-examples configure script to use pkg-config for the
+ extra form/menu/panel libraries, to be more consistent with the
+ handling of the curses/ncurses library.
+ + modify test-packages for mingw to supply "pc" files.
+ + modify gen-pkgconfig.in to list -lpthread as a private library when
+ configured to access it via weak symbols.
+ + simplify gen-pkgconfig.in, adding -ltinfo without the special linker
+ checks because some versions of the linker simply hard-code the
+ behavior.
+ + update URLs for ncurses website to use https.
+ + modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
+ ncurses-examples are built with a system ncurses that lacks the
+ standard "curses" symbolic link, as done by SuSE. The symbol is
+ needed to make a followup check for the pthread library work, and
+ would be set properly using the options "--with-screen", etc.
+ + generate misc/*.pc with "all" rule, as done for "sources" rule
+ (report by Jeffrey Walton).
+
+20171230
+ + build-fix for ncurses-examples with Fedora27, adding check for
+ reset_color_pairs() -- not yet in Fedora's package.
+ + consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
+ script when the latter happens to use the C compiler rather than

+ e.g., if there is a permission problem.
+ + minor fix for progs/toe.c, using _nc_free_termtype2.

+ + improve curs_attr.3x discussion of color pairs.
+
+20171209
+ + modify misc/ncurses-config.in to make output with --includedir
+ consistent with --cflags, i.e., when --disable-overwrite option was
+ configured the output should show the subdirectory where headers
+ are.
+ + modify MKlib_gen.sh to suppress macros when calling an "implemented"
+ function in link_test.c
+ + updated ftp-url used in test-packages, etc.
+ + modify order of -pie/-shared options in configure script in case

+ + correct array-index when parsing "-T" command-line option in tabs
+ program.
+ + modify demo_new_pair.c to pass extended pairs to setcchar().
+ + add test/dots_xcurses.c to illustrate a different approach used for
+ extended colors which can be contrasted with dots_curses.c.
+ + add a check in tic to note when a description uses non-mandatory
+ delays without xon_xoff. This is not an error, but some descriptions
+ for a terminal emulator may use the combination incorrectly.
+
+20171007
+ + modify "-T" option of clear and tput to call use_tioctl() to obtain
+ the operating system's notion of the screensize if possible.
+ + review/repair some exit-codes for tput, making usage-message exit
+ with 2 rather than 1, and a failure to open terminal 4+errno.

+ + improve animation in test/xmas.c by adding a time-delay in blinkit().
+ + modify several test programs to reflect that ncurses honors existing
+ signal handlers in initscr(), while other implementations do not.
+ + modify bs.c to make it easier to quit.
+ + change ncurses-examples to use attr_t vs chtype to follow X/Open
+ documentation more closely since Solaris xpg4-curses uses different
+ values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
+ short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
+ two sets.
+
+20170923
+ + modify menu for test/ncurses.c to fit on 24-line screen.
+ + build-fix for configure --with-caps=uwin
+ + add options to test_arrays.c, for selecting termcap vs terminfo, etc.

+ + fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+ + corrected a warning from tic about keys which are the same, to skip

+ + add check in _nc_parse_entry() for invalid entry name, setting the
+ name to "invalid" to avoid problems storing entries.
+ + add/improve checks in tic's parser to address invalid input
+ + add a check in comp_scan.c to handle the special case where a

+ + modify install-rule for ncurses-examples to put the data files in
+ /usr/share/ncurses-examples
+ + improve tracemunch, by changing address-parameters of add_wch(),
+ color_content() and pair_content() to dummy parameters.
+ + minor optimization to _nc_change_pair, to return quickly when the
+ current screen is marked for clearing.
+ + in-progress changes to improve performance of test/picsmap.c for
+ loading image files.
+ + modify allocation for SCREEN's color-pair table to start small, grow
+ on demand up to the existing limit.
+ + add "RGB" extension capability for direct-color support, use this to
+ improve color_content().
+ + improve picsmap test-program:
+ + if no palette file is needed, attempt to load one based on $TERM,
+ checking first in the current directory, then by adding ".dat"
+ suffix, and finally in the data-directory, e.g.,
+ /usr/share/ncurses-examples
+ + add "-l" option for logging
+ + add "-d" option for debugging
+ + add "-s" option for stepping automatically through list of images,

+ + move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
+ Williams) -TD
+ + add a check in newline_forces_scroll() in case a program moves the

+ + improve _nc_tparm_analyze, using that to extend the checks made by
+ tic for reporting inconsistencies between the expected number of
+ parameters for a capability and the actual.
+ + amend handling of repeat_char capability in EmitRange (adapted from
+ report/patch by Dick Wesseling):
+ + translate the character to the alternate character set when the
+ alternate character set is enabled.
+ + do not use repeat_char for characters past 255.
+ + document "_nc_free_tinfo" in manual page, because it could be used in
+ tack for memory-leak checking.
+ + add "--without-tack" configure option to refine "--with-progs"
+ configure option. Normally tack is no longer built in-tree, but
+ a few packagers combine it during the build. If term_entry.h is
+ installed, there is no advantage to in-tree builds.
+ + adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
+ needed for tack 1.08 when built in-tree. Rather than relying upon
+ internal "_nc_" functions, tack now uses the boolean, number and
+ string capability name-arrays provided by ncurses and SVr4 Unix
+ curses. It still uses term_entry.h for the definitions of the
+ extended capability arrays.
+ + add an overlooked null-pointer check in mvcur changes from 20170722
+
+20170722
+ + improve test-packages for ncurses-examples and AdaCurses for lintian
+ + modify logic for endwin-state to be able to detect the case where
+ the screen was never initialized, using that to trigger a flush of
+ ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
+ term-driver configuration.
+ + add dependency upon ncurses_cfg.h to a few other internal header
+ files to allow each to be compiled separately.
+ + add dependency upon ncurses_cfg.h to tic's header-files; any program
+ using tic-library will have to supply this file. Legacy tack
+ versions supply this file; ongoing tack development has dropped the
+ dependency upon tic-library and new releases will not be affected.
+
+20170715
+ + modify command-line parameters for "convert" used in picsmap to work
+ with ImageMagick 6.8 and newer.
+ + fix build-problem with tack and ABI-5 (Debian #868328).

+20170708
+ + add a note to tic manual page about -W versus -f options.
+ + correct a limit-check in fixes from 20170701 (report by Sven Joachim).
+
+20170701
+ + modify update_getenv() in db_iterator.c to ensure that environment
+ variables which are not initially set will be checked later if an
+ application happens to set them (patch by Guillaume Maudoux).
+ + remove initialization-check for calling napms() in the term-driver
+ configuration; none is needed.
+ + add help-screen to test/test_getstr.c and test/test_get_wstr.c
+ + improve compatibility between different configurations of new_prescr,
+ fixing a case with threaded code and term-driver where c++/demo did
+ not work (cf: 20160213).
+ + the fixes for Redhat #1464685 obscured a problem subsequently
+ reported in Redhat #1464687; the given test-case was no longer
+ reproducible. Testing without the fixes for the earlier reports
+ showed a problem with buffer overflow in dump_entry.c, which is
+ addressed by reducing the use of a fixed-size buffer.
+ + add/improve checks in tic's parser to address invalid input
+ (Redhat #1464684, #1464685, #1464686, #1464691).
+ + alloc_entry.c, add a check for a null-pointer.
+ + parse_entry.c, add several checks for valid pointers as well as
+ one check to ensure that a single character on a line is not
+ treated as the 2-character termcap short-name.
+ + fix a memory leak in delscreen() (report by Bai Junq).
+ + improve tracemunch, showing thread identifiers as names.
+ + fix a use-after-free in NCursesMenu::~NCursesMenu()
+ + further amend incorrect calls for memory-leaks from 20170617 changes
+ (report by Allen Hewes).
+
+20170624
+ + modify c++/etip.h.in to accommodate deprecation of throw() and
+ throws() in c++17 (prompted by patch by Romain Geissler).
+ + remove some incorrect calls for memory-leaks from 20170617 changes
+ (report by Allen Hewes).
+ + add test-programs for termattrs and term_attrs.
+ + modify _nc_outc_wrapper to use the standard output if the screen was
+ not initialized, rather than returning an error.
+ + improve checks for low-level terminfo functions when the terminal
+ has not been initialized (Redhat #1345963).
+ + modify make_hash to allow building with address-sanitizer,
+ assuming that --disable-leaks is configured.
+ + amend changes for number_format() in 20170506 to avoid undefined
+ behavior when shifting (patch by Emanuele Giaquinta).
+
+20170617
+ + fill in some places where TERMTYPE2 vs TERMTYPE was not used
+ (report by Allen Hewes).
+ + use ExitTerminfo() internally in error-exits for ncurses' setupterm
+ to help with leak checking.
+ + use ExitProgram() in error-exit from initscr() to help with leak
+ checking.
+ + review test-programs, adding checks for cases where the terminal
+ cannot be initialized.
+
+20170610
+ + add option "-xp" to picsmap.c, to use init_extended_pair().
+ + make simple performance fixes for picsmap.c
+ + improve aspect ratio of images read from "convert" in picsmap.c
+
+20170603
+ + add option to picsmap to use color-palette files, e.g., for mapping
+ to xterm-256color.
+ + move the data in SCREEN used for the alloc_pair() function to the
+ end, to restore compatibility between ncurses/ncursesw libtinfo
+ (report/patch by Miroslav Lichvar).
+ + add build-time utility "report_offsets" to help show when the various
+ configurations of tinfo library are compatible or not.
+
+20170527
+ + improved test/picsmap.c:
+ + lookup named colors for xpm files in rgb.txt
+ + accept blanks in color-keys for xpm files.
+ + if neither xbm/xpm work, try "convert", which may be available.
+
+20170520
+ + modify test/picsmap.c to read xpm files.
+ + modify package/debian/* to create documentation packages, so the
+ related files can be checked with lintian.
+ + fix some typos in manpages (report/patch by Sven Joachim).
+
+20170513
+ + add test/picsmap.c to fill in some testing issues not met by dots.
+ The initial version reads X bitmap (".xbm") files.
+ + repair logic which forces a repaint where a color-pair's content is
+ changed (cf: 20170311).
+ + improve tracemunch, showing screenXX pointers as names.
+
+20170506
+ + modify tic/infocmp display of numeric values to use hexadecimal when

+ + add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c
+
+20170429
+ + corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
+ overlooked in 20160528 fixes (report by Alexandre Bury).
+ + improve a couple of test-program's help-messages.
+ + corrected loop in rain.c from 20170415 changes.
+ + modify winnstr and winchnstr to return error if the output pointer is
+ null, as well as adding a null pointer check of the window pointer
+ for better compatibility with other implementations.
+ + improve discussion of NetBSD curses in scr_dump.5
+ + modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
+ value to be limited (reports by Darby Payne, Rob Boudreau).
+ + update config.guess, config.sub from

+
+20170422
+ + build-fix for termcap-configuration (report by Chi-Hsuan Yen).
+ + improve terminfo manual page discussion of control- and graphics-
+ characters.
+ + remove tic warning about "^?" in string capabilities, which was
+ marked as an extension (cf: 20000610, 20110820); however all Unix
+ implementations support this and X/Open Curses does not address it.
+ On the other hand, termcap never did support this feature.
+ + correct missing comma-separator between string capabilities in
+ icl6402 and m2-nam -TD
+ + restore rmir/smir in ansi+idc to better match original ansiterm+idc,
+ add alias ansiterm (report by Robert King).
+ + amend an old check for ambiguous use of "ma" in terminfo versus
+ a termcap use, if the capability is cancelled to treat it as number.
+ + correct a case in _nc_captoinfo() which read "%%" and emitted "%".
+ + modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
+ and "%'char'%+%c" to check that the final character is really 'c',
+ avoiding a case in icl6404 which cannot be converted to termcap.
+ + in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
+ written to termcap, because the BSDs did not implement that.
+ + in _nc_tic_expand() and _nc_infotocap(), improve string-length check
+ when deciding whether to use "^X" or "\xxx" format for control
+ characters, to make the output of tic/infocmp more predictable.
+ + limit termcap "%d" width to 2 digits on input, and use "%2" in
+ preference to "%02" on output.
+ + correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
+ "%3"; the result repeated the last character.
+ + add man/scr_dump.5 to document screen-dump format.
+
+20170415
+ + modify several test programs to use new popup_msgs, adapted from
+ help-screen used in test/edit_field.c
+ + drop two symbols obsoleted in 2004: _nc_check_termtype, and
+ _nc_resolve_uses
+ + fix some old copyright dates (cf: 20031025).
+ + build-fixes for test/savescreen.c to work with AIX and HPUX.
+ + minor fix to configure script, adding a backslash/continuation.
+ + extend TERMINAL structure for ABI 6 to store numbers internally as
+ integers rather than short, by adding new data for this purpose.
+ + more fixes for minor memory-leaks in test-programs.
+
+20170408
+ + change logic in wins_nwstr() to avoid addressing data past the output

+ + add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
+ (discussion with Nicholas Marriott)
+ + add test-programs sp_tinfo and extended_color
+ + modify no-leaks code for lib_cur_term.c to account for the tgetent()
+ cache.
+ + modify setupterm() to save original tty-modes so that erasechar()
+ works as expected. Also modify _nc_setupscreen() to avoid redundant
+ calls to get original tty-modes.
+ + modify set_curterm() to update ttytype[] data used by longname().
+ + modify wattr_set() and wattr_get() to return ERR if win-parameter is
+ null, as documented.
+ + improve cast used for null-pointer checks in header macros, to
+ reduce compiler warnings.
+ + modify several functions, using the reserved "opts" parameter to pass
+ color- and pair-values larger than 16-bits:
+ + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),

+ + Other functions call these with the corresponding altered behavior,
+ including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
+ slk_color_off(), vid_attr().
+ + add new functions for manipulating color- and pair-values larger
+ than 16-bits. These are extended_color_content(),
+ extended_pair_content(), extended_slk_color(), init_extended_color(),
+ init_extended_pair(), and the corresponding sp-funcs.
+

+ + add new function "unfocus_current_field" (Leon Winter)
+
+20161022
+ + modify tset -w (and tput reset) to update the program's copy of the
+ screensize if it was already set in the system, to improve tabstop
+ setting which relies upon knowing the actual screensize.
+ + add functionality of tset -w to tput, like the "-c" feature this is
+ not optional in tput.
+ + add "clear" as a possible link/alias to tput.
+ + improve tput's check for being called as "init" or "reset" to allow
+ for transformed names.
+ + split-out the "clear" function from progs/clear.c, share with
+ tput to get the same behavior, e.g., the E3 extension.
+
+20161015
+ + amend internal use of tputs to consistently use the number of lines
+ affected, e.g., for insert/delete character operations. While
+ merging terminfo source early in 1995, several descriptions used the
+ "*" proportional delay for these operations, prompting a change in
+ doupdate.
+ + regenerate llib-* files.
+ + regenerate HTML manpages.
+ + fix several formatting issues with manual pages.
+
+20161008
+ + adjust size in infocmp/tic to work with strlcpy.

+
+20160903
+ + correct 20100515 change for weak signals versus sigprocmask (report
+ by Rich Coe).
+ + modify misc/Makefile.in to work around OpenBSD "make" which unlike
+ all other versions of "make" does not recognize continuation lines
+ of comments.
+ + amend the last change to CF_C_ENV_FLAGS to move only the
+ preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
+ leaving the residue in CC. That happens to work for gcc's various

+ by Sven Joachim).
+
+20160827

+ as "ccache" (report by Enrico Scholz).
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20160820
+ + update tput manual page to reflect changes to manipulate terminal
+ modes by sharing functions with tset.
+ + add the terminal-mode parts of "reset" (aka tset) to the "tput reset"
+ command, making the two almost the same except for window-size.
+ + adapt logic used in dialog "--keep-tite" option for test/filter.c as
+ "-a" option. When set, test/filter attempts to suppress the
+ alternate screen.
+ + correct a typo in interix entry -TD
+
+20160813
+ + add a dependency upon generated-sources in Ada95/src/Makefile.in to

+ + improve CF_GNU_SOURCE configure macro to optionally define
+ _DEFAULT_SOURCE work around a nuisance in recent glibc releases.
+ + move the terminfo-specific parts of tput's "reset" function into

+ with tput.
+
+20160730
