+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.
+
+20161203
+ + improve discussion of field validation in form_driver.3x manual page.
+ + update curs_trace.3x manual page.
+
+20161126
+ + modify linux-16color to not mask dim, standout or reverse with the
+ ncv capability -TD
+ + add 0.1sec mandatory delay to flash capabilities using the VT100
+ reverse-video control -TD
+ + omit selection of ISO-8859-1 for G0 in enacs capability from linux2.6
+ entry, to avoid conflict with the user-defined mapping. The reset
+ feature will use ISO-8859-1 in any case (Mikulas Patocka).
+ + improve check in tic for delays by also warning about beep/flash
+ when a delay is not embedded, or if those use the VT100 reverse
+ video escape without using a delay.
+ + minor fix for syntax-check of delays from 20161119 changes.
+ + modify trace() to avoid overwriting existing file (report by Maor
+ Shwartz).
+
+20161119
+ + add check in tic for some syntax errors of delays, as well as use of
+ proportional delays for non-line capabilities.
+ + document history of the clear program and the E3 extension, prompted
+ by various discussions including
+ http://unix.stackexchange.com/questions/87469/clearing-the-old-scrollback-buffer
+
+20161112
+ + improve -W option in tic/infocmp:
+ + correct order of size-adjustments in wrapped lines
+ + if -f option splits line, do not further split it with -W
+ + begin a new line when adding "use=" after a wrapped line
+
+20161105
+ + fix typo in man/terminfo.tail (Alain Williams).
+ + correct program-name in adacurses6-config.1 manual page.
+
+20161029
+ + 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.
+ + fix configure script to record when strlcat is found on OpenBSD.
+ + build-fix for "recent" OpenBSD vs baudrate.
+
+20161001
+ + add -W option to tic/infocmp to force long strings to wrap. This is
+ in addition to the -w option which attempts to fit capabilities into
+ a given line-length.
+ + add linux-m1 minitel entries (patch by Alexandre Montaron).
+ + correct rs2 string for vt100-nam -TD
+
+20160924
+ + modify _nc_tic_expand to escape comma if it immediately follows a
+ percent sign, to work with minitel change.
+ + updated minitel and viewdata descriptions (Alexandre Montaron).
+
+20160917
+ + build-fix for gnat6, which unhelpfully attempts to compile C files.
+ + fix typo in 20160910 changes (Debian #837892, patch by Sven Joachim).
+
+20160910
+ + trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with
+ Leon Winter).
+ + trim some obsolete/incorrect wording about EINTR from wgetch manual
+ page (patch by Leon Winter).
+ + really correct 20100515 change (patch by Rich Coe).
+ + add "--enable-string-hacks" option to test/configure
+ + completed string-hacks for "sprintf", etc., including test-programs.
+ + make "--enable-string-hacks" work with Debian by checking for the
+ "bsd" library and its associated "<bsd/string.h>" header.
+
+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
+ "model" options, but may require tuning for other compilers (report
+ by Sven Joachim).
+
+20160827
+ + add "v" menu entry to test/ncurses.c to show baudrate and other
+ values.
+ + add "newer" baudrate symbols from Linux and FreeBSD to progs/tset.c,
+ lib_baudrate.c
+ + modify CF_XOPEN_SOURCE macro:
+ + add "uclinux" to case for "linux" (patch by Yann E. Morin)
+ + modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
+ (patch by Corinna Vinschen, from changes to tin).
+ + improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
+ 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
+ handle a case of "configure && make install".
+ + trim trailing blanks from include/Caps*, to work around a problem
+ in sed (Debian #818067).
+
