-
-          <ul>
-            <li>add <code>U8</code> feature to denote entries for
-            terminal emulators which do not support VT100 SI/SO
-            when processing UTF-8 encoding</li>

-          </ul>
-        </li>
-
-        <li>improvements based on new checks in tic:</li>
-
-        <li style="list-style: none; display: inline">
-          <ul>
-            <li>fill in no-parameter forms of cursor-movement where
-            a parameterized form is available</li>
-

-        <li>repurpose <code>gnome</code> terminfo entries as
-        <code>vte</code>, retaining <code>gnome</code> variants for

-
-  <h2>Major bug fixes</h2>
-
-  <ul>
-    <li>ncurses library
-
-      <ul>
-        <li>wide character support
-
-          <ul>
-            <li>modify length returned by <code>getcchar</code> to
-            count the trailing null which is documented in
-            X/Open.</li>
-
-            <li>fix an infinite recursion when adding a
-            legacy-coding 8-bit value using
-            <code>insch</code>.</li>
-
-            <li>improve a workaround in adding wide-characters,
-            when a control character is found. The library uses
-            <code>unctrl</code> to obtain a printable version of
-            the control character, but was not passing color or
-            video attributes.</li>
-
-            <li>modify <code>waddch_literal</code>, updating
-            line-pointer after a multicolumn character is found to
-            not fit on the current row, and wrapping is done. Since
-            the line-pointer was not updated, the wrapped
-            multicolumn character was written to the beginning of
-            the current row.</li>
-
-            <li>fixes in <code>wins_nwstr</code> and related
-            functions to ensure that special characters, i.e.,
-            control characters are handled properly with the
-            wide-character configuration.</li>
-
-            <li>correct internal <code>_nc_insert_ch</code> to use
-            <code>_nc_insert_wch</code> when inserting wide
-            characters, since the <code>wins_wch</code> function
-            that it used did not update the cursor position.</li>
-          </ul>
-        </li>
-
-        <li>mouse
-
-          <ul>
-            <li>add check if <code>Gpm_Open</code> returns a -2,
-            e.g., for "xterm". This is normally suppressed but can
-            be overridden using <code>$NCURSES_GPM_TERMS</code>.
-            Ensure that <code>Gpm_Close</code> is called in this
-            case.</li>
-
-            <li>add check in mouse-driver to disable connection if
-            GPM returns a zero, indicating that the connection is
-            closed.</li>
-
-            <li>modify <code>getmouse</code> to act as its
-            documentation implied, returning on each call the
-            preceding event until none are left. When no more
-            events remain, it will return <code>ERR</code>.</li>
-          </ul>
-        </li>
-
-        <li>miscellaneous
-
-          <ul>
-            <li>improve handling of color-pairs embedded in
-            attributes for the extended-colors configuration.</li>
-
-            <li>add check for failure to open hashed-database
-            needed for db4.6.</li>
-
-            <li>modify use of <code>$CC</code> environment variable
-            which is defined by X/Open as a curses feature, to
-            ignore it if it is not a single character.</li>
-
-            <li>modify declaration of <code>cur_term</code> when
-            broken-linker is used, but enable-reentrant is not, to
-            match pre-5.7.</li>
-
-            <li>correct limit-checks in <code>derwin</code>.</li>
-
-            <li>remove old check in <code>mvderwin</code> which
-            prevented moving a derived window whose origin happened
-            to coincide with its parent's origin.</li>
-
-            <li>correct limit-checks in <code>newwin</code>, to
-            ensure that windows have nonzero size.</li>
-
-            <li>modify <code>set_curterm</code> to make
-            broken-linker configuration work with changes from
-            20090228.</li>
-
-            <li>modify <code>wgetch</code> to ensure it checks
-            <code>SIGWINCH</code> when it gets an error in
-            non-blocking mode.</li>
-
-            <li>correct limit-check in <code>wredrawln</code>,
-            accounting for <code>begy</code>/<code>begx</code>
-            values.</li>
-
-            <li>fix a null-pointer check in
-            <code>_nc_format_slks</code> in lib_slk.c, from
-            20070704 changes.</li>
-
-            <li>correct translation of "^" in
-            <code>_nc_infotocap</code>, used to transform terminfo
-            to termcap strings.</li>
-
-            <li>modify <code>_nc_wgetch</code> to check for a -1 in
-            the fifo, e.g., after a <code>SIGWINCH</code>, and
-            discard that value, to avoid confusing
-            application.</li>
-          </ul>
-        </li>
-      </ul>
-    </li>
-
-    <li>other libraries
-
-      <ul>
-        <li>correct transfer of multicolumn characters in multirow
-        <code>field_buffer</code>, which stopped at the end of the
-        first row due to filling of unused entries in a cchar_t
-        array with nulls.</li>
-
-        <li>correct buffer-size after internal resizing of
-        wide-character <code>set_field_buffer</code>, broken in
-        20081018 changes.</li>
-
-        <li>correct layout of working window used to extract data
-        in wide-character configured by
-        <code>set_field_buffer</code></li>
-      </ul>
-    </li>

-            directory if needed.</li>
-
-            <li>fix typo "<code>==</code>" where "<code>=</code>"
-            is needed in <code>ncurses-config.in</code> and
-            <code>gen-pkgconfig.in</code> files.</li>
-
-            <li>modify <code>gen-pkgconfig.in</code> to eliminate a
-            dependency on rpath when deciding whether to add
-            <code>$LIBS</code> to <code>--libs</code> output; that
-            should be shown for the ncurses and tinfo libraries
-            without taking rpath into account.</li>
-
-            <li>modify handling of <code>$PKG_CONFIG_LIBDIR</code>
-            to use only the first item in a possibly
-            colon-separated list.</li>
-          </ul>
-        </li>
-
-        <li>other packaging issues
-
-          <ul>
-            <li>add <code>make-tar.sh</code> scripts to Ada95 and
-            test subdirectories to help with making those
-            separately distributable.</li>
-
-            <li>add <code>Ada95/configure</code> script, to use in
-            tar-file created by
-            <code>Ada95/make-tar.sh</code>.</li>
-
-            <li>remove <code>tar-copy.sh</code> and related
-            <code>configure/Makefile</code> chunks, since the Ada95
-            binding is now installed using rules in
-            <code>Ada95/src</code>.</li>
-          </ul>
-        </li>
-      </ul>
-    </li>
-
-    <li>cross-compiling:
-
-      <ul>
-        <li>improve configure checks for location of tic and
-        infocmp programs used for installing database and for
-        generating fallback data, e.g., for cross-compiling.</li>
-
-        <li>modify #define's for build-compiler to suppress cchar_t
-        symbol from compile of <code>make_hash</code> and
-        <code>make_keys</code>, improving cross-compilation of
-        ncursesw.</li>
-
-        <li>simplify include-dependencies of <code>make_hash</code>
-        and <code>make_keys</code>, to reduce the need for setting
-        BUILD_CPPFLAGS in cross-compiling when the build- and
-        target-machines differ.</li>
-
-        <li>correct cross-compiling configure check for
-        <code>CF_MKSTEMP</code> macro, by adding a check cache
-        variable set by <code>AC_CHECK_FUNC</code>.</li>
-      </ul>
-    </li>
-
-    <li>library dependencies:
-
-      <ul>
-        <li>revise <code>wadd_wch</code> and
-        <code>wecho_wchar</code> to eliminate dependency on
-        <code>unctrl</code>.</li>
-
-        <li>adjust configure script so that "t" is not added to
-        library suffix when weak-symbols are used, allowing the
-        pthread configuration to more closely match the non-thread
-        naming.</li>
-      </ul>
-    </li>
-
-    <li>building the Ada95 tree:
-
-      <ul>
-        <li>changes to use gnatmake project files in the Ada95
-        tree.</li>
-
-        <li>add/use configure check to turn on project rules for
-        <code>Ada95/src</code>.</li>
-
-        <li>old gnatmake (3.15) does not produce libraries using
-        project-file; work around by adding script to generate
-        alternate makefile.</li>
-
-        <li>add configure --with-ada-sharedlib option, for the
-        test_make rule.</li>
-
-        <li>move Ada95-related logic into aclocal.m4, since
-        additional checks will be needed to distinguish old/new
-        implementations of gnat.</li>
-
-        <li>add test_make / test_clean / test_install rules in
-        Ada95/src</li>
-
-        <li>change install-path for adainclude directory to
-        /usr/share/ada (was /usr/lib/ada).</li>
-      </ul>
-    </li>
-
-    <li>other configure/build issues:
-
-      <ul>
-        <li>make <code>CCHARW_MAX</code> value configurable, noting
-        that changing this would change the size of
-        <code>cchar_t</code>, and would be ABI-incompatible.</li>
-
-        <li>improve comparison of program-names when checking for
-        linked flavors such as "reset" by ignoring the executable
-        suffix.</li>
-
-        <li>drop <code>mkdirs.sh</code>, use
-        "<code>mkdir&nbsp;-p</code>".</li>
-
-        <li>drop <code>misc/ncu-indent</code> and
-        <code>misc/jpf-indent</code>; they are provided by an
-        external package <a href=
-        "http://invisible-island.net/cindent/cindent.html">cindent</a>.</li>
-
-        <li>change makefiles to use <code>$ARFLAGS</code> rather
-        than <code>$AR_OPTS</code>, provide a configure check to
-        detect whether a "-" is needed before "ar" options.</li>
-
-        <li>modify <code>CF_DISABLE_LEAKS</code> configure macro so
-        that the --enable-leaks option is not the same as
-        --disable-leaks.</li>
-
-        <li>improve configure script macros
-        <code>CF_HEADER_PATH</code> and
-        <code>CF_LIBRARY_PATH</code> by adding <code>CFLAGS</code>,
-        <code>CPPFLAGS</code> and <code>LDFLAGS</code>,
-        <code>LIBS</code> values to the search-lists.</li>
-
-        <li>improve configure macros <code>CF_GCC_VERSION</code>
-        and <code>CF_GCC_WARNINGS</code> to work with gcc 4.x's c89
-        alias, which gives warning messages for cases where older
-        versions would produce an error.</li>
-
-        <li>modify <code>CF_WITH_LIBTOOL</code> configure check to
-        allow unreleased libtool version numbers (e.g. which
-        include alphabetic chars, as well as digits, after the
-        final '.').</li>
-
-        <li>improve use of symbolic links in makefiles by using
-        "<code>-f</code>" option if it is supported, to eliminate
-        temporary removal of the target</li>
-
-        <li>add a configure-time check to pick a suitable value for
-        <code>CC_SHARED_OPTS</code> for Solaris.</li>
-
-        <li>add -shared option to <code>MK_SHARED_LIB</code> when
-        -Bsharable is used, for *BSD's, without which "main" might
-        be one of the shared library's dependencies.</li>
-
-        <li>modify configure script to allow building shared
-        libraries with gcc on AIX 5 or 6.</li>
-
-        <li>suppress configure check for static/dynamic linker
-        flags for gcc on Solaris 10, since gcc is confused by
-        absence of static libc, and does not switch back to dynamic
-        mode before finishing the libraries.</li>
-
-        <li>suppress configure check for static/dynamic linker
-        flags for gcc on Darwin.</li>
-
-        <li>modify <code>misc/run_tic.in</code> to create parent
-        directory, in case this is a new install of hashed
-        database.</li>
-
-        <li>modify configure check for tic program, used for
-        fallbacks, to a warning if not found. This makes it simpler
-        to use additonal scripts to bootstrap the fallbacks code
-        using tic from the build tree.</li>
-      </ul>
-    </li>
-
-    <li>test programs:
-
-      <ul>
-        <li>add test/demo_terminfo, for comparison with
-        demo_termcap.</li>
-
-        <li>improve test/ncurses.c 'F' test, show combining
-        characters in color.</li>
-
-        <li>fix logic for 'V' in test/ncurses.c tests f/F.</li>
-
-        <li>improve test/ncurses.c 'a test to put mouse droppings
-        in the proper window.</li>
-
-        <li>modify ncurses 'F' test to demo wborder_set with
-        colored lines.</li>
-
-        <li>modify ncurses 'f' test to demo wborder with colored
-        lines.</li>
-
-        <li>improve test/ncurses.c 'a' test, using unctrl more
-        consistently to display meta-characters.</li>
-
-        <li>correct use of <code>key_name</code> in test/ncurses.c
-        'A' test, which only displays wide-characters, not
-        key-codes since 20070612.</li>
-
-        <li>add test/clip_printw.c to illustrate how to use printw
-        without wrapping.</li>
-
-        <li>modify test-programs, e.g,. test/view.c, to address
-        subtle differences between Tru64/Solaris and HPUX/AIX
-        getcchar return values.</li>
-
-        <li>add some test programs (and make these use the same
-        special keys by sharing <code>linedata.h</code> functions):
-        test/test_addstr.c test/test_addwstr.c test/test_addchstr.c
-        test/test_add_wchstr.c</li>
-
-        <li>add test/xterm-256color.dat</li>
-
-        <li>modify test programs to allow them to be built with
-        NetBSD curses.</li>
-
-        <li>fixes for test programs to build/work on HPUX and AIX,
-        etc.</li>
-      </ul>
-    </li>
+  <li>fixes a longstanding portability problem with its use of the
+      <a href="http://invisible-island.net/ncurses/man/form_fieldtype.3x">set_field_type</a>
+      function.  Because that function uses variable-length argument lists,
+      its interface with gnat does not work with certain platforms.
+  <li>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.
+      <p>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
+      <a href="http://invisible-island.net/ncurses/ncurses-Ada95.html">here</a>.
+  <li>additional improvements were made for portability of the
+      ncurses examples, adding rpm- and dpkg-scripts for test-builds.
+      See 
+      <a href="http://invisible-island.net/ncurses/ncurses-examples.html">this page</a>
