- * The principal source of changes to the interface comes from the
- release of X/Open Curses in 1997. Earlier versions of ncurses (4.0
- and before) were based on a draft version of the specification.
- The release version adds parameters to some functions to support
- the evolving internationalization of curses. These summarize the
- impact:
- + modified several prototypes to correspond with 1997 version
- of X/Open Curses (affects ABI since developers have used
- attr_get).
- + corrected prototypes for slk_* functions, using chtype rather
- than attr_t.
- + the slk_attr_{set,off,on} functions need an additional void*
- parameter according to XSI.
- + correct macros for wattr_set, wattr_get, separate wattrset
- macro from these to preserve behavior that allows attributes
- to be combined with color pair numbers.
- + reviewed/updated curses.h, term.h against X/Open Curses Issue
- 4 Version 2. This includes making some parameters
- NCURSES_CONST rather than const, e.g., in termcap.h.
- + reviewed/corrected macros in curses.h as per XSI document.
- + add set_a_attributes and set_pglen_inch to terminfo
- structure, as per XSI and Solaris 2.5.
- * The newest version of the X/Open Curses is implemented on Solaris
- and other vendor's systems. It adds new features to the terminfo
- descriptions:
- + implement tparm %l format.
- + implement tparm printf-style width and precision for %s, %d,
- %x, %o as per XSI.
- * We made additional changes to reduce impact by future interface
- changes:
- + rename key_names[] array to _nc_key_names since it is not
- part of the curses interface.
- + move macro winch to a function, to hide details of struct
- ldat
- * modify configure script to embed ABI in shared libraries for HP-UX
- 10.x (detailed request by Tim Mooney).
- * modify configuration of shared libraries on Digital Unix so that
- versioning is embedded in the library, rather than implied by
- links (patch by Tim Mooney).
-
- New features:
- * enable sigwinch handler by default.
- * turn on hashmap scrolling code by default
- * improved support for termcap applications
- + modify tput to accept termcap names as an alternative to
- terminfo names.
- + provide support for termcap PC variable by copying it from
- terminfo data and using it as the padding character in tputs.
- + provide support for termcap ospeed variable by copying it
- from the internal cur_term member, and using ospeed as the
- baudrate reference for the delay_output and tputs functions.
- + change name-comparisons in lib_termcap to compare no more
- than 2 characters.
- + add configure option --enable-tcap-names, which essentially
- allows users to define new capabilities as in termcap.
- * add mouse support to ncurses menus.
- * add mouse and dll support for OS/2 EMX
- * modify terminfo parsing to accept octal and hexadecimal constants
- * add configure option --enable-no-padding, to allow environment
- variable $NCURSES_NO_PADDING to eliminate non-mandatory padding,
- thereby making terminal emulators (e.g., for vt100) a little more
- efficient.
- * modify lib_color.c to eliminate dependency on orig_colors and
- orig_pair, since SVr4 curses does not require these either, but
- uses them when they are available.
- * add -f option to infocmp and tic, which formats the terminfo
- if/then/else/endif so that they are readable (with newlines and
- tabs).
- * modify tic to compile into %'char' form in preference to
- %{number}, since that is a little more efficient.
-
+ * terminfo installs "xterm-new" as "xterm" entry rather than
+ "xterm-old" (aka xterm-r6).
+ * terminfo data is installed using the tic -x option (few systems
+ still use ncurses 4.2).
+ * modify C++ binding to work with newer C++ compilers by providing
+ initializers and using modern casts. Old-style header names are
+ still used in this release to allow compiling with not-so-old
+ compilers.
+ * modify parameter type in c++ binding for insch() and mvwinsch() to
+ be consistent with underlying ncurses library (was char, is
+ chtype).
+ * change NCursesWindow::err_handler() to a virtual function.
+ * form and menu libraries now work with wide-character data.
+ Applications which bypassed the form library and manipulated the
+ FIELD.buf data directly will not work properly with libformw,
+ since that no longer points to an array of char. The
+ set_field_buffer() and field_buffer() functions translate to/from
+ the actual field data.
+ * add symbol to curses.h which can be used to suppress include of
+ stdbool.h, e.g.,
+ #define NCURSES_ENABLE_STDBOOL_H 0
+ #include <curses.h>
+
+ * 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.
+ * winnstr() now returns multibyte character strings for the
+ wide-character configuration.
+ * assume_default_colors() no longer requires that
+ use_default_colors() be called first.
+ * data_ahead() now works with wide-characters.
+ * slk_set() and slk_wset() now accept and store multibyte or
+ multicolumn characters.
+ * start_color() now returns OK if colors have already been started.
+ start_color() also returns ERR if it cannot allocate memory.
+ * pair_content() now returns -1 for consistency with init_pair() if
+ it corresponds to the default-color.
+ * unctrl() now returns null if its parameter does not correspond to
+ an unsigned char.
+
+ New features and improvements:
+ * library
+ + environment variable NCURSES_NO_UTF8_ACS supports
+ miscellaneous terminal emulators which ignore alternate
+ character set escape sequences when in UTF-8 mode.
+ + 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.
+ + change GPM initialization, using dl library to load it
+ dynamically at runtime.
+ + form, menu and panel libraries support debug-tracing.
+ * add NCURSES-Programming-HOWTO.html by Pradeep Padala (see
+ http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/).
+ * programs:
+ * infocmp:
+ + The -i option now matches 8-bit controls against its table
+ entries, e.g., so it can analyze the xterm-8bit entry.
+ + 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.
+ * tic:
+ + modify termcap-parsing to retain 2-character aliases at the
+ beginning of an entry if the "-x" option is used in tic.
+ + filter out long extended names when translating to termcap
+ format. Only two characters are permissible for termcap
+ capability names.
+ + correct translation of "%%" in terminfo format to termcap,
+ e.g., using "tic -C".
+ + 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.
+ + add a check for improperly ended strings, i.e., where a
+ following line begins in column 1.
+ + 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.
+ + add check (with debug configuration) that provides about the
+ runtime changes that would be made to sgr0 for termcap
+ applications.
+ * tset:
+ + 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.
