+ <li>add symbol to curses.h which can be used to suppress include of
+ stdbool.h, e.g.,
+ <pre>
+ #define NCURSES_ENABLE_STDBOOL_H 0
+ #include <curses.h>
+ </pre>
+
+ <li>change SP->_current_attr to a pointer, adjust ifdef's to ensure
+ that libtinfo.so and libtinfow.so have the same ABI. The reason
+ for this is that the corresponding data which belongs to the
+ upper-level ncurses library has a different size in each model.
+
+ <li>winnstr() now returns multibyte character strings for the
+ wide-character configuration.
+
+ <li>assume_default_colors() no longer requires that
+ use_default_colors() be called first.
+
+ <li>data_ahead() now works with wide-characters.
+
+ <li>slk_set() and slk_wset() now accept and store multibyte or
+ multicolumn characters.
+
+ <li>start_color() now returns OK if colors have
+ already been started.
+ start_color() also returns ERR if it cannot allocate memory.
+
+ <li>pair_content() now returns -1 for consistency with init_pair()
+ if it corresponds to the default-color.
+
+ <li>unctrl() now returns null if its parameter does not correspond
+ to an unsigned char.
+
+</ul>
+New features and improvements:
+<ul>
+ <li>library
+ <ul>
+ <li>environment variable NCURSES_NO_UTF8_ACS supports
+ miscellaneous terminal emulators which ignore alternate
+ character set escape sequences when in UTF-8 mode.
+
+ <li>modify initialization of key lookup table so that if an extended
+ capability (tic -x) string is defined, and its name begins with 'k',
+ ncurses will automatically treat it as a key.
+
+ <li>change GPM initialization, using dl library to load it
+ dynamically at runtime.
+
+ <li>form, menu and panel libraries support debug-tracing.
+
+ </ul>
+
+ <li>add NCURSES-Programming-HOWTO.html by Pradeep Padala
+ (see http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/).
+
+ <li>programs:
+
+ <li>infocmp:
+ <ul>
+ <li>The -i option now matches 8-bit controls against its table
+ entries, e.g., so it can analyze the xterm-8bit entry.
+
+ <li>add "-x" option to infocmp like tic's "-x", for use in "-F"
+ comparisons. This modifies infocmp to only report extended
+ capabilities if the -x option is given, making this more
+ consistent with tic. Some scripts may break, since infocmp
+ previous gave this information without an option.
+
+ </ul>
+
+ <li>tic:
+
+ <ul>
+
+ <li>modify termcap-parsing to retain 2-character aliases at the
+ beginning of an entry if the "-x" option is used in tic.
+
+ <li>filter out long extended names when translating to termcap
+ format. Only two characters are permissible for termcap
+ capability names.
+
+ <li>correct translation of "%%" in terminfo format to termcap,
+ e.g., using "tic -C".
+
+ <li>modify the "-c -v" options to ignore delays when comparing
+ strings. Also modify it to ignore a canceled sgr string,
+ e.g., for terminals which cannot properly combine attributes
+ in one control sequence.
+
+ <li>add a check for improperly ended strings, i.e., where a
+ following line begins in column 1.
+
+ <li>add a check in tic for terminfo entries having an sgr0 but no
+ sgr string. This confuses Tru64 and HPUX curses when combined
+ with color, e.g., making them leave line-drawing characters in
+ odd places.
+
+ <li>add check (with debug configuration) that provides about the
+ runtime changes that would be made to sgr0 for termcap
+ applications.
+
+ </ul>
+
+ <li>tset:
+
+ <ul>
+
+ <li>add -c and -w options to allow user to suppress ncurses'
+ resizing of the terminal emulator window in the special case
+ where it is not able to detect the true size.
+
+ </ul>
+
+</ul>
+Major bug fixes:
+<ul>
+
+ <li>improve logic in tgetent() which adjusts the termcap "me" string
+ to work with ISO-2022 string used in xterm-new.
+ This is a feature that was incompletely implemented in ncurses 5.3.
+ ncurses attempts to provide termcap clients with the portion of
+ the sgr0 (termcap "me") string that does not reset line-drawing.
+
+ <li>cells in the WINDOW which are continuations of a multicolumn
+ character are encoded differently, making repainting more
+ reliable.
+
+ <li>amend change to setupterm() in ncurses 5.4 (20030405) which would
+ reuse the value of cur_term if the same output was selected. This
+ now reuses it only when setupterm() is called from tgetent(),
+ which has no notion of separate SCREENs. Note that tgetent() must
+ be called after initscr() or newterm() to use this feature.
+
+ <li>make setcchar() now works when its wchar_t* parameter is
+ pointing to a string which contains more data than can be converted.
+
+ <li>win_wchnstr() now works for more than one cell.
+
+ <li>resizeterm() now processes all levels of window hierarchy.
+
+ <li>disable GPM mouse support when $TERM happens to be prefixed with
+ "xterm". Gpm_Open() would otherwise assert that it can deal with
+ mouse events in this case.
+
+ <li>add SP->_screen_acs_map[], used to ensure that mapping of missing
+ line-drawing characters is handled properly. For example, ACS_DARROW
+ is absent from xterm-new, and it was coincidentally displayed the
+ same as ACS_BTEE.
+
+</ul>
+
+Portability:
+<ul>
+ <li>configure script:
+ <ul>
+ <li>new options:
+ <dl>
+ <dt>--enable-largefile
+ <dd>set compiler and linker flags to use largefile support.
+
+ <dt>--enable-ext-colors
+ <dd>Allow encoding of 256 foreground
+ and background colors, e.g., with the xterm-256color or
+ xterm-88color terminfo entries.
+ This requires ABI 6 because it changes the size of cchar_t.
+
+ <dt>--enable-ext-mouse
+ <dd>This defines NCURSES_MOUSE_VERSION 2, and modifies the encoding of
+ mouse events to support wheel mice, which may transmit buttons
+ 4 and 5. This works with xterm and similar terminal
+ emulators.
+ This requires ABI 6 because it changes the encoding of
+ mouse events.
+
+ <dt>--with-chtype
+ <dd>overriding of the non-LP64 model's use of chtype
+
+ <dt>--with-mmask-t
+ <dd>overriding of the non-LP64 model's use of mmask_t
+
+ <dt>--without-xterm-new
+ <dd>Installs "xterm-old" as the "xterm" entry of the terminfo
+ database.
+
+ </dl>
+
+ <li>The --with-termlib option now accepts a value which sets
+ the name of the terminfo library. This would allow a packager to
+ build libtinfow.so renamed to coincide with libtinfo.so
+
+ <li>fixes/improvements for cross-compiling:
+
+ <ul>
+ <li>suppress $suffix in misc/run_tic.sh when cross-compiling.
+ This allows cross-compiles to use the host's tic program to
+ handle the "make install.data" step.
+
+ <li>correct BUILD_CPPFLAGS substitution in ncurses/Makefile.in, to allow
+ cross-compiling from a separate directory tree.
+
+ </ul>
+
+ </ul>
+
+ <li>library:
+ <ul>
+
+ <li>add ifdef's for _LP64 in curses.h to avoid using wasteful
+ 64-bits for chtype and mmask_t, but add configure option
+ --disable-lp64 in case anyone used that configuration.
+
+ <li>modify C++ binding to use some C internal functions to make it
+ compile properly on Solaris (and other platforms).
+
+ <li>remove check in newwin() that prevents allocating windows that
+ extend beyond the screen (Solaris does this).
+
+ <li>check for <code>nl_langinfo(CODESET)</code>, use it if available.
+ This replaces ad hoc tests of environment variables to
+ check if the terminal is setup for UTF-8 encoding.
+ Applications which do not call <code>setlocale()</code>
+ should be corrected, to make them work properly with
+ UTF-8 encoding.
+ <br>
+ <strong>In particular, applications which assume (and
+ do not call <code>setlocale()</code>) that
+ Latin-1 codes are printable will no longer work in
+ a UTF-8 locale since the ad hoc check of environment
+ variables to see if the locale was UTF-8 is not used
+ when <code>nl_langinfo(CODESET)</code> is available.</strong>
+
+ <li>use setlocale() to query the program's current locale rather
+ than using getenv(). This supports applications which rely
+ upon legacy treatment of 8-bit characters when the locale is
+ not initialized.
+
+ </ul>
+</ul>
