+These are the highlights from the change-log since ncurses 5.6 release.
Interface changes:
<li>generate linkable stubs for some macros:
- getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
- getpary, getpary,
- <br>
- and (for libncursesw)
- <br>
- wgetbkgrnd
+ getattrs
New features and improvements:
- <li>support hashed databases for the terminal descriptions.
- This uses the Berkeley database, has been tested for
- several versions on different platforms.
- <li>add <code>use_legacy_coding()</code> function to support
- lynx's font-switching feature.
- <li>add extension <code>nofilter()</code>, to cancel a prior
- <code>filter()</code> call.
- <li>add/install a package config script, e.g.,
- <code>ncurses5-config</code> or
- <code>ncursesw5-config</code>, according to
- configuration options.
- <li>provide ifdef for <code>NCURSES_NOMACROS</code> which
- suppresses most macro definitions from curses.h, i.e.,
- where a macro is defined to override a function to improve
- performance.
- <li>make ifdef's consistent in <code>curses.h</code> for the
- extended colors so the header file can be used for the
- normal curses library. The header file installed for
- extended colors is a variation of the wide-character
- configuration.
- <li>improve <code>tgetstr()</code> by making the return value
- point into the user's buffer, if provided.
- <li>add ifdef's allowing ncurses to be built with
- <code>tparm()</code> using either varargs (the existing
- status), or using a fixed-parameter list (to match X/Open).
- <li>widen the test for xterm <code>kmous</code> a little to
- <code>allow</code> for other
- strings than "\E[M", e.g., for <code>xterm-sco</code>
- functionality in xterm.
- <li>modify <code>wgetnstr()</code> to return
- <code>KEY_RESIZE</code> if a sigwinch occurs.
- <li>move prototypes for wide-character trace functions from
- curses.tail to curses.wide to avoid accidental reference to
- those if <code>_XOPEN_SOURCE_EXTENDED</code> is defined
- without ensuring that &lt;wchar.h&gt; is included.
- <li>change the way shared libraries (other than libtool) are
- installed. Rather than copying the build-tree's libraries,
- link the shared objects into the install directory. This
- makes the <code>--with-rpath</code> option work except with
- <code>$(DESTDIR)</code>.
- <li>several improvements for rendering in hpterm. These are
- only available if the library is configured using
- <code>--enable-xmc-glitch</code>.
- <li>Add <code>NCURSES_NO_HARD_TABS</code> and
- <code>NCURSES_NO_MAGIC_COOKIE</code> environment variables
- to allow runtime suppression of the related hard-tabs and
- xmc-glitch features.
+ <li>new flavor of the ncurses library provides rudimentary
+ support for POSIX threads. Several functions are
+ reentrant, but most require either a window-level or
+ screen-level mutex.<br>
+ (This is <em>API</em>-compatible,
+ but not <em>ABI</em>-compatible with the normal library).
+ <li>add <code>NCURSES_OPAQUE</code> symbol to curses.h, will
+ use to make structs opaque in selected configurations.
+ <li>add <code>NCURSES_EXT_FUNCS</code> and
+ <code>NCURSES_EXT_COLORS</code> symbols to curses.h to make
+ it simpler to tell if the extended functions and/or colors
+ are declared.
+ <li>add wresize() to C++ binding
+ <li>eliminate fixed-buffer vsprintf() calls in C++ binding.
+ <li>add several functions to C++ binding which wrap C functions
+ that pass a WINDOW* parameter.
+ <li>adapt mouse-handling code from menu library in form-library
+ <li>improve tracing for form library, showing created forms,
+ fields, etc.
+ <li>make $NCURSES_NO_PADDING feature work for termcap interface .
+ <li>add check to trace-file open, if the given name is a
+ directory, add ".log" to the name and try again.
+ <li>several new manpages: curs_legacy.3x, curs_memleaks.3x,
+ curs_opaque.3x and curs_threads.3x
- <li>add new test programs: chgat.c, demo_altkeys.c,
- echochar.c, foldkeys.c, movewindow.c, redraw.c, (noting
- that existing test programs also were modified to test
- additional features).
- <li>modify tack to test extended capability function-key
- strings.
+ <li>modified three test-programs to demonstrate the threading
+ support in this version: ditto, rain, worm.
- <li>modify toe to access termcap data, e.g., via <code>cgetent()</code>
- functions, or as a text file if those are not available.
+ <li>several new test-programs: demo_panels, dots_mvcur,
+ inch_wide, inchs, key_name, key_names, savescreen,
+ savescreen.sh test_arrays, test_get_wstr, test_getstr,
+ test_instr, test_inwstr and test_opaque.
- <li>improve infocmp/tic <code>-f</code> option formatting.
+ <li>add <code>adacurses-config</code> to the Ada95 install.
- <li>add <code>toe -a</code> option, to show all databases.
- This uses new private interfaces in the ncurses library for
- iterating through the list of databases.
+ <li>modify tic <code>-f</code> option to format spaces as
+ <code>\s</code> to prevent them from being lost when that
+ is read back in unformatted strings.
- <li>modify <code>MKfallback.sh</code> to use
- <code>tic&nbsp;-x</code> when constructing fallback tables to
- allow extended capabilities to be retrieved from a fallback entry.
+ <li>The <code>tack</code> program is now distributed separately
+ from ncurses.
<li>terminal database
- <li>add terminfo entries for xfce terminal (xfce) and multi gnome terminal (mgt)
- <li>add nsterm-16color entry
- <li>updated mlterm terminfo entry
- <li>add kon, kon2 and jfbterm terminfo entry
- <li>remove invis capability from klone+sgr, mainly used by linux entry, since it does not really do this
- <li>add ka2, kb1, kb3, kc2 to vt220-keypad as an extension
- <li>add shifted up/down arrow codes to xterm-new as kind/kri strings
- <li>add hpterm-color terminfo entry
- <li>add 256color variants of terminfo entries for programs which are reported to implement this feature
- <li>correct order of use-clauses in rxvt-basic entry which made codes for f1-f4 vt100-style rather than vt220-style.
+ <li>added entries:
+ <ul>
+ <li><code>Eterm-256color</code>,
+ <code>Eterm-88color</code> and
+ <code>rxvt-88color</code>
+ <li><code>aterm</code>
+ <li><code>konsole-256color</code>
+ <li><code>mrxvt</code>
+ <li><code>screen.mlterm</code>
+ <li><code>screen.rxvt</code>
+ <li><code>teraterm4.59</code> is now the primary primary
+ teraterm entry, renamed original to
+ <code>teraterm2.3</code>
+ <li><code>9term</code> terminal
+ <li>Newbury Data entries
+ </ul>
+ <li>updated/improved entries:
+ <ul>
+ <li><code>gnome</code> to version 2.22.3
+ <li><code>h19</code>, <code>z100</code>
+ <li><code>konsole</code> to version 1.6.6

+ to <a href="http://invisible-island.net/xterm/xterm.log.html#xterm_230">xterm patch #230</a>.
+ </ul>
Major bug fixes:
- <li>correct a typo in configure <code>--with-bool</code> option for the
- case where <code>--without-cxx</code> is used.
+ <li>add logic to tic for cancelling strings in user-defined
+ capabilities
+ (this is <em>needed</em> for
+ current <code>konsole</code> terminfo entry).
+ <li>modify <code>mk-1st.awk</code> so the generated makefile rules for
+ linking or installing shared libraries do not first remove the
+ library, in case it is in use, e.g., <code>libncurses.so</code> by
+ <code>/bin/sh</code>.
+ <li>correct check for notimeout() in wgetch().
+ <li>fix a sign-extension bug in infocmp's repair_acsc() function.
- <li>move assignment from environment variable <code>ESCDELAY</code>
- from <code>initscr()</code> down to <code>newterm()</code> so the
- environment variable affects timeouts for terminals opened with
- newterm() as well.
+ <li>change winnstr() to stop at the end of the line.
- <li>modify <code>werase</code> to clear multicolumn characters that
- extend into a derived window.
+ <li>make Ada95 demo_panels() example work.
- <li>modify <code>wchgat()</code> to mark updated cells as changed so a
- refresh will repaint those cells.
+ <li>fix for adding a non-spacing character at the beginning of a line.
- <li>correct logic in <code>wadd_wch()</code> and
- <code>wecho_wch()</code>, which did not guard against passing the
- multi-column attribute into a call on <code>waddch()</code>, e.g.,
- using data returned by <code>win_wch()</code>
+ <li>fill in extended-color pair to make colors work
+ for wide-characters using extended-colors.
- <li>fix redrawing of windows other than <code>stdscr</code> using
- <code>wredrawln()</code> by touching the corresponding rows in
- <code>curscr</code>.
+ <li>improve refresh of window on top of multi-column characters,
+ taking into account split characters on left/right window
+ boundaries.
- <li>reduce memory leaks in repeated calls to <code>tgetent()</code> by
- remembering the last <code>TERMINAL*</code> value allocated to hold
- the corresponding data and freeing that if the
- <code>tgetent()</code> result buffer is the same as the previous
- call.
+ <li>modify <code>win_wchnstr()</code> to ensure that only a base cell
+ is returned for each multi-column character.
- <li>modify <code>read_termtype()</code> so the <code>term_names</code>
- data is always allocated as part of the <code>str_table</code>, a
- better fix for a memory leak.
+ <li>improve <code>waddch()</code> and <code>winsch()</code> handling of
+ EILSEQ from <code>mbrtowc()</code> by using <code>unctrl()</code>
+ to display illegal bytes rather than trying to append further bytes
+ to make up a valid sequence.
- <li>fix <code>wins_nwstr(),</code> which did not handle single-column
- non-8bit codes.
+ <li>restore <code>curs_set()</code> state after
+ <code>endwin()</code>/<code>refresh()</code>
- <li>modify <code>wbkgrnd()</code> to avoid clearing the
- <code>A_CHARTEXT</code> attribute bits since those record the state
- of multicolumn characters.
+ <li>modify <code>keyname()</code> to use "^X" form only if
+ <code>meta()</code> has been called, or if <code>keyname()</code>
+ is called without initializing curses, e.g., via
+ <code>initscr()</code> or <code>newterm()</code>.
- <li>improve <code>SIGWINCH</code> handling by postponing its effect
- during <code>newterm()</code>, etc., when allocating screens.
+ <li>modify <code>unctrl()</code> to check codes in 128-255 range versus
+ <code>isprint()</code>.
+ If they are not printable, and locale was set, use a "M-" or "~"
+ sequence.
- <li>remove 970913 feature for copying subwindows as they are moved in
- <code>mvwin()</code>.
+ <li>improve <code>resizeterm()</code> by moving ripped-off lines, and
+ repainting the soft-keys.
- <li>add checks in <code>waddchnstr()</code> and
- <code>wadd_wchnstr()</code> to stop copying when a null character
- is found.
+ <li>modify form library to accept control characters such as newline
+ in set_field_buffer(), which is compatible with Solaris.
- <li>add some checks to ensure current position is within scrolling
- region before scrolling on a new line.
+ <li>use <code>NCURSES_MOUSE_MASK()</code> in definition of
+ <code>BUTTON_RELEASE()</code>, etc., to make those work properly
+ with the <code>--enable-ext-mouse</code> configuration
- <li>add a workaround to ACS mapping to allow applications such as
- test/blue.c to use the "PC ROM" characters by masking them with
- A_ALTCHARSET. This worked up til 5.5, but was lost in the revision
- of legacy coding.
+ <li>correct some functions in Ada95 binding which were using return
+ value from C where none was returned.
+ <li>reviewed/fixed issues reported by Coverity and Klocwork tools.
