+   through   5.8;  very  few  applications  will  require  recompilation,
    depending   on  the  platform.  These  are  the  highlights  from  the
-   change-log since ncurses 5.6 release.
-
-   Interface changes:
-     * generate linkable stubs for some macros:
-       getattrs
-
-   New features and improvements:
-     * library
-          + 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.
-            (This  is  API-compatible,  but  not  ABI-compatible with the
-            normal library).
-          + add  NCURSES_OPAQUE  symbol  to  curses.h,  will  use to make
-            structs opaque in selected configurations.
-          + add   NCURSES_EXT_FUNCS  and  NCURSES_EXT_COLORS  symbols  to
-            curses.h to make it simpler to tell if the extended functions
-            and/or colors are declared.
-          + add wresize() to C++ binding
-          + eliminate fixed-buffer vsprintf() calls in C++ binding.
-          + add  several  functions to C++ binding which wrap C functions
-            that pass a WINDOW* parameter.
-          + adapt mouse-handling code from menu library in form-library
-          + improve  tracing  for  form  library,  showing created forms,
-            fields, etc.
-          + make $NCURSES_NO_PADDING feature work for termcap interface .
-          + add  check  to  trace-file  open,  if  the  given  name  is a
-            directory, add ".log" to the name and try again.
-          + several   new   manpages:  curs_legacy.3x,  curs_memleaks.3x,
-            curs_opaque.3x and curs_threads.3x
-     * programs:
-          + modified  three  test-programs  to  demonstrate the threading
-            support in this version: ditto, rain, worm.
-          + 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.
-          + add adacurses-config to the Ada95 install.
-          + modify  tic  -f option to format spaces as \s to prevent them
-            from  being  lost  when  that  is  read  back  in unformatted
-            strings.
-          + The tack program is now distributed separately from ncurses.
-     * terminal database
-          + added entries:
-               o Eterm-256color, Eterm-88color and rxvt-88color
-               o aterm
-               o konsole-256color
-               o mrxvt
-               o screen.mlterm

-               o xterm, and building-blocks for function-keys to [3]xterm
-                 patch #230.
-
-   Major bug fixes:
-     * add   logic   to   tic  for  cancelling  strings  in  user-defined
-       capabilities (this is needed for current konsole terminfo entry).
-     * modify  mk-1st.awk  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., libncurses.so by /bin/sh.
-     * correct check for notimeout() in wgetch().
-     * fix a sign-extension bug in infocmp's repair_acsc() function.
-     * change winnstr() to stop at the end of the line.
-     * make Ada95 demo_panels() example work.
-     * fix for adding a non-spacing character at the beginning of a line.
-     * fill   in   extended-color   pair   to   make   colors   work  for
-       wide-characters using extended-colors.
-     * improve  refresh  of  window  on  top  of multi-column characters,
-       taking   into   account  split  characters  on  left/right  window
-       boundaries.
-     * modify  win_wchnstr()  to ensure that only a base cell is returned
-       for each multi-column character.
-     * improve waddch() and winsch() handling of EILSEQ from mbrtowc() by
-       using  unctrl()  to  display  illegal  bytes rather than trying to
-       append further bytes to make up a valid sequence.
-     * restore curs_set() state after endwin()/refresh()
-     * modify  keyname() to use "^X" form only if meta() has been called,
-       or  if  keyname() is called without initializing curses, e.g., via
-       initscr() or newterm().
-     * modify  unctrl() to check codes in 128-255 range versus isprint().
-       If  they  are not printable, and locale was set, use a "M-" or "~"
-       sequence.
-     * improve  resizeterm()  by  moving ripped-off lines, and repainting
-       the soft-keys.
-     * modify  form  library to accept control characters such as newline
-       in set_field_buffer(), which is compatible with Solaris.
-     * use  NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc.,
-       to   make   those   work   properly  with  the  --enable-ext-mouse
-       configuration
-     * correct  some  functions  in Ada95 binding which were using return
-       value from C where none was returned.
-     * reviewed/fixed issues reported by Coverity and Klocwork tools.

-   Portability:
-     * configure script:

-                      control  whether static string tables are generated
-                      as   single   large  strings  (to  improve  startup
-                      performance), or as array of individual strings.
-
-              --disable-relink
-                      control   whether  shared  libraries  are  relinked

-                      make   explicit  whether  tic  library  depends  on
-                      ncurses/ncursesw library.
-
-              --enable-mixed-case
-                      override   the  configure  script's  check  if  the
-                      filesystem   supports  mixed-case  filenames.  This
-                      allows  one  to  control  how the terminal database
-                      maps to the filesystem. For filesystems that do not
-                      support   mixed-case,  the  library  uses  generate
-                      2-character (hexadecimal) codes for the lower-level
-                      of the filesystem terminfo database
-
-              --enable-reentrant
-                      builds  a  different  flavor of the ncurses library
-                      (ncursest)  which  improves  reentrant  use  of the
-                      library  by  reducing  global  and static variables
-                      (see  the  "--with-pthread" option for the threaded
-                      support).
-
-              --enable-weak-symbols
-                      use  weak-symbols  for  linking to the POSIX thread
-                      library,  and  use  the same soname for the ncurses
-                      shared  library  as the normal library (caveat: the
-                      ABI is for the threaded library, which makes global
-                      data accessed via functions).
-
-              --with-pthread
-                      build  with  the  POSIX thread library (tested with
-                      AIX,   Linux,   FreeBSD,   OpenBSD,  HPUX,  IRIX64,
-                      Solaris, Tru64).
-
-              --with-ticlib
-                      build/install   the   tic-support  functions  in  a
-                      separate library
-
-          + improved options:
-
-              --enable-ext-colors
-                      requires the wide-character configuration.
-
-              --with-chtype
-                      ignore  option  value "unsigned" is always added to
-                      the   type   in   curses.h;   do   the   same   for
-                      --with-mmask-t.
-
-              --with-dmalloc
-                      build-fix for redefinition of strndup.
-
-              --with-hashed-db
-                      accepts  a parameter which is the install-prefix of
-                      a given Berkeley Database.
-
-              --with-hashed-db
-                      the $LIBS environment variable overrides the search
-                      for the db library.
-
-              --without-hashed-db
-                      assumed when "--disable-database" is used.
-
-     * other configure/build issues:
-          + build-fixes for LynxOS
-          + modify  shared-library  rules  to  allow  FreeBSD  3.x to use
-            rpath.
-          + build-fix for FreeBSD "contemporary" TTY interface.
-          + build-fixes for AIX with libtool.
-          + build-fixes for Darwin and libtool.
-          + modify BeOS-specific ifdef's to build on Haiku.
-          + corrected  gcc  options  for  building  shared  libraries  on
-            Solaris and IRIX64.
-          + change  shared-library  configuration for OpenBSD, make rpath
-            work.
-          + build-fixes for using libutf8, e.g., on OpenBSD 3.7
-          + add   "-e"  option  in  ncurses/Makefile.in  when  generating
-            source-files  to  force earlier exit if the build environment
-            fails unexpectedly.
-          + add support for shared libraries for QNX.
-          + change  delimiter  in  MKlib_gen.sh from '%' to '@', to avoid
-            substitution  by  IBM xlc to '#' as part of its extensions to
-            digraphs.
-     * library:
-          + rewrite  wrapper  for  wcrtomb(),  making it work on Solaris.
-            This  is  used in the form library to determine the length of
-            the buffer needed by field_buffer.
-          + add/use  configure  script  macro  CF_SIG_ATOMIC_T,  use  the
-            corresponding type for data manipulated by signal handlers.
-          + set locale in misc/ncurses-config.in since it uses a range
-          + disable  GPM  mouse  support  when  $TERM  does not happen to
-            contain  "linux",  since  Gpm_Open()  no  longer  limits  its
-            assertion  to  terminals  that  it might handle, e.g., within
-            "screen" in xterm.
-          + reset mouse file-descriptor when unloading GPM library.
-     * test programs:
-          + update  test  programs to build/work with various UNIX curses
-            for comparisons.
+   change-log since ncurses 5.8 release.
+
+   This  is  a  bug-fix  release,  correcting  a  small  number of urgent
+   problems in the ncurses library from the 5.8 release.
+
+   It also improves the Ada95 binding:
+     * fixes  a  longstanding  portability  problem  with  its use of the
+       [3]set_field_type    function.    Because   that   function   uses
+       variable-length  argument  lists, its interface with gnat does not
+       work with certain platforms.
+     * improves  configurability and portability, particularly when built
+       separately  from the main ncurses tree. The 5.8 release introduced
+       scripts  which  can be used to construct separate tarballs for the
+       Ada95 and ncurses examples.
+       Those  were a proof of concept. For the 5.9 release, those scripts
+       are  augmented  with  rpm-  and  dpkg-scripts  used in test builds
+       against  a  variety of gnat- and system ncurses versions as old as
+       gnat  3.15  and  ncurses  5.4  (see  snapshots  and systems tested
+       [4]here.
+     * additional  improvements  were made for portability of the ncurses
+       examples,  adding  rpm-  and  dpkg-scripts  for  test-builds.  See
+       [5]this page for snapshots and other information.
