+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).
+ + fix a couple of broken links in generated man-html documentation.
+ + regenerate man-html documentation.
+
+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
+ + improve description of endwin() in manual.
+ + modify setcchar() and getcchar() to treat negative color-pair as an
+ 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
+ available only when ncurses is configured for tracing.
+ + amend change from 20161231 to avoid writing traces to the standard
+ error after initializing the trace feature using the environment
+ variable.
+
+20170107
+ + amend changes for tput to reset tty modes to "sane" if the program
+ is run as "reset", like tset. Likewise, ensure that tset sends
+ either reset- or init-strings.
+ + improve manual page descriptions of tput init/reset and tset/reset,
+ to make it easier to see how they are similar and different.
+ + move a static result from key_name() to _nc_globals
+ + modify _nc_get_screensize to allow for use_env() and use_tioctl()
+ state to be per-screen when sp-funcs are configured, better matching
+ the behavior when using the term-driver configuration.
+ + improve cross-references in manual pages for often used functions
+ + move SCREEN field for use_tioctl() data before the ncursesw fields,
+ and limit that to the sp-funcs configuration to improve termlib
+ compatibility (cf: 20120714).
+ + correct order of initialization for traces in use_env() and
+ use_tioctl() versus first trace calls.
+
+20161231
+ + fix errata for ncurses-howto (report by Damien Ruscoe).
+ + fix a few places in configure/build scripts where DESTDIR and rpath
+ were combined (report by Thomas Klausner).
+ + merge current st description (report by Harry Gindi) -TD
+ + modify flash capability for linux and wyse entries to put the delay
+ between the reverse/normal escapes rather than after -TD
+ + modify program tabs to pass the actual tty file descriptor to
+ setupterm rather than the standard output, making padding work
+ consistently.
+ + explain in clear's manual page that it writes to stdout.
+ + add special case for verbose debugging traces of command-line
+ utilities which write to stderr (cf: 20161126).
+ + remove a trace with literal escapes from skip_DECSCNM(), added in
+ 20161203.
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20161224
+ + correct parmeters for copywin call in _nc_Synchronize_Attributes()
+ (patch by Leon Winter).
+ + improve color-handling section in terminfo manual page (prompted by
+ patch by Mihail Konev).
+ + modify programs clear, tput and tset to pass the actual tty file
+ descriptor to setupterm rather than the standard output, making
+ padding work.
+
+20161217
+ + add tput-colorcube demo script.
+ + add -r and -s options to tput-initc demo, to match usage in xterm.
+ + flush the standard output in _nc_flush for the case where SP is zero,
+ e.g., when called via putp. This fixes a scenario where "tput flash"
+ did not work after changes in 20130112.
+
+20161210
+ + add configure script option --disable-wattr-macros for use in cases
+ where one wants to use the same headers for ncurses5/ncurses6
+ development, by suppressing the wattr* macros which differ due to
+ the introduction of extended colors (prompted by comments in
+ Debian #230990, Redhat #1270534).
+ + add test/tput-initc to demonstrate tput used to initialize palette
+ from a data file.
+ + modify test/xterm*.dat to use the newer color4/color12 values.
+
