+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).
+ + repair termcap-format from tic/infocmp broken in 20170701 fixes
+ (Debian #868266).
+ + reformat terminfo.src with 20170513 updates.
+ + improve test-packages to address lintian warnings.
+
+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
+ they are "close" to a power of two, making the result more readable.
+ + improve discussion of portability in curs_mouse.3x
+ + change line-length for generated html/manpages to 78 columns from 65.
+ + improve discussion of line-drawing characters in curs_add_wch.3x
+ (prompted by discussion with Lorinczy Zsigmond).
+ + cleanup formatting of hackguide.html and ncurses-intro.html
+ + 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
+ http://git.savannah.gnu.org/cgit/config.git
+
+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
+ of mbstowcs().
+ + correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
+ + fix minor memory-leaks in test-programs.
+ + further improve ifdef in term_entry.h for internal definitions not
+ used by tack.
+
+20170401
+ + minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
+ + add smso for env230, to match sgr -TD
+ + remove p7/protect from sgr in fbterm -TD
+ + drop setf/setb from fbterm; setaf/setab are enough -TD
+ + make xterm-pcolor sgr consistent with other capabilities -TD
+ + 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(),
+ wattr_set(), wchgat(), wcolor_set().
+ + 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.
+
+20170325
+ + fix a memory leak in the window-list when creating multiple screens
+ (reports by Andres Martinelli, Debian #783486).
+ + reviewed calls from link_test.c, added a few more null-pointer
+ checks.
+ + add a null-pointer check in ungetmouse, in case mousemask was not
+ called (report by "Kau").
+ + updated curs_sp_funcs.3x for new functions.
+
+20170318
+ + change TERMINAL structure in term.h to make it opaque. Some
+ applications misuse its members, e.g., directly modifying it
+ rather than using def_prog_mode().
+ + modify utility headers such as tic.h to make it clearer which are
+ externals that are used by tack.
+ + improve curs_slk.3x in particular its discussion of portability.
+ + fix cut/paste in legacy_encoding.3x
+ + add prototype for find_pair() to new_pair.3x (report by Branden
+ Robinson).

+
+20170311
+ + modify vt100 rs2 string to reset vt52 mode and scrolling regions
+ (report/analysis by Robert King) -TD
+ + add vt100+4bsd building block, use that for older terminals rather
+ than "vt100" which is now mostly used as a building block for
+ terminal emulators -TD
+ + correct a few spelling errors in terminfo.src comments -TD
+ + add fbterm -TD
+ + fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
+ + changed internal colorpair_t to a struct, eliminating an internal
+ 8-bit limit on colors
+ + add ncurses/new_pair.h
+ + add ncurses/base/new_pair.c with alloc_pair(), find_pair() and
+ free_pair() functions
+ + add test/demo_new_pair.c

+20170304
+ + improve terminfo manual description of terminfo syntax.
+ + clarify the use of wint_t vs wchar_t in curs_get_wstr.3x

+ error.
+ + fix a typo in include/hashed_db.h (Andre Sa).
+
+20170225
+ + fixes for CF_CC_ENV_FLAGS (report by Ross Burton).
+
+20170218
+ + fix several formatting issues with manual pages.
+ + correct read of terminfo entry in which all strings are absent or
+ explicitly cancelled. Before this fix, the result was that all were
+ treated as only absent.
+ + modify infocmp to suppress mixture of absent/cancelled capabilities
+ that would only show as "NULL, NULL", unless the -q option is used,
+ e.g., to show "-, @" or "@, -".
+
+20170212
+ + build-fixes for PGI compilers (report by Adam J. Stewart)
+ + accept whitespace in sed expression for generating expanded.c
+ + modify configure check that g++ compiler warnings are not used.
+ + add configure check for -fPIC option needed for shared libraries.
+ + let configure --disable-ext-funcs override the default for the
+ --enable-sp-funcs option.
+ + mark some structs in form/menu/panel libraries as potentially opaque
+ without modifying API/ABI.
+ + add configure option --enable-opaque-curses for ncurses library and
+ similar options for the other libraries.
+
+20170204
+ + trim newlines, tabs and escaped newlines from terminfo "paths" passed
+ to db-iterator.
+ + ignore zero-length files in db-iterator; these are useful for
+ instance to suppress "$HOME/.terminfo" when not wanted.
+ + amended "b64:" encoder to work with the terminfo reader.
+ + modify terminfo reader to accept "b64:" format using RFC-3548 in
+ as well as RFC-4648 url/filename-safe format.
+ + modify terminfo reader to accept "hex:" format as generated by
+ "infocmp -0qQ1" (cf: 20150905).
+ + adjust authors comment to reflect drop below 1% for SV.
+
+20170128
+ + minor comment-fixes to help automate links to bug-urls -TD
+ + add dvtm, dvtm-256color -TD
+ + add settings corresponding to xterm-keys option to tmux entry to
+ reflect upcoming change to make that option "on" by default
+ (patch by Nicholas Marriott).
+ + uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
+ + add dumb-emacs-ansi -TD
+
+20170121
+ + improve discussion of early history of tput program.
+ + incorporate A_COLOR mask into COLOR_PAIR(), in case user application
+ provides an out-of-range pair number (report by Elijah Stone).
+ + clarify description in tput manual page regarding support for
+ termcap names (prompted by FreeBSD #214709).
+ + remove a restriction in tput's support for termcap names which
+ omitted capabilities normally not shown in termcap translations
+ (cf: 990123).
+ + modify configure script for clang as used on FreeBSD, to work around
+ clang's differences in exit codes vs gcc.
+
20170114
+ improve discussion of early history of tset/reset programs.
+ clarify in manual pages that the optional verbose option level is
