<h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
<h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <p>There are no new features in this release.</p>
+ <p>These are new features:</p>
+
+ <ul>
+ <li>
+ <p>The low-level terminfo and termcap interfaces are used
+ both by the higher-level curses library, as well as by many
+ applications.</p>
+
+ <p>The functions which convert parameterized terminal
+ capability strings for output to the terminal
+ (<code>tiparm</code> and <code>tparm</code>) analyze the
+ capability string to determine which parameters are strings
+ (i.e., addresses), versus numbers (not addresses).</p>
+
+ <p>The library's analysis of a capability string may differ
+ from the calling application's design if environment
+ variables are used to point to an invalid terminal database.
+ This is a longstanding problem with <em>all</em>
+ implementations of terminfo, dating from the early 1980s.</p>
+
+ <p>Two new functions address this problem: by providing a
+ function which allows the calling application to tell ncurses
+ how many string-parameters to expect:</p>
+
+ <ul>
+ <li><code>tiscan_s</code> helps applications check
+ formatting capabilities that would be passed to
+ <code>tiparm_s</code>.</li>
+
+ <li><code>tiparm_s</code> provides applications a way to
+ tell ncurses what the expected parameters are for a
+ capability.</li>
+ </ul>
+ </li>
+
+ <li>
+ <p>The ncurses library supports a compile-time feature
+ (enabled with the configure <code>--enable-check-size</code>
+ option) which simplifies initialization with terminals which
+ do not negotiate window (screen) size. This is done in
+ <code>setupterm</code>, by providing for using ANSI
+ cursor-position report (in user6/user7 terminfo capabilities)
+ to obtain the screen size if neither environment variables or
+ ioctl is used.</p>
+
+ <p>The ncurses test-program with options
+ “<code>-E -T</code>” demonstrates this
+ feature.</p>
+ </li>
+
+ <li>add functions to query tty-flags in
+ <code>SCREEN</code></li>
+ </ul>
+
+ <p>This release drops compatibility with obsolete versions of
+ <a href="@HOMEPAGE@/tack/">tack</a>, e.g., pre-1.08</p>
<h4><a name="h4-fixes-library" id="h4-fixes-library">Other
improvements</a></h4>
<ul>
<li>
- <p>modify <tt>delscreen</tt> to more effectively delete all
- windows on the given screen.</p>
+ <p>In addition to the new, safer function
+ <code>tiparm_s</code>, ncurses adds checks to make the older
+ <code>tiparm</code>, <code>tparm</code> and
+ <code>tgoto</code> functions safer:</p>
+
+ <ul>
+ <li>
+ <p>the terminfo functions <code>tiparm</code> and
+ <code>tparm</code> ensure that the capability string
+ comes from the terminal description which ncurses loads,
+ rather than from random data which the application
+ happens to have.</p>
+ </li>
+
+ <li>
+ <p>the <code>tgoto</code> function disallows capabilities
+ which its analysis shows will attempt to use string
+ parameters.</p>
+ </li>
+
+ <li>
+ <p>ncurses uses internal functions which correspond to
+ <code>tiparm</code>, and <code>tgoto</code> which ensure
+ that the capability strings which are passed to these
+ functions come from the loaded terminal description.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>improve check in <code>lib_tparm.c</code>, ensuring that a
+ char* fits into a <code>TPARM_ARG</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>_nc_syserr_abort</code> to use
+ <code>_nc_env_access</code>, rather than only checking root
+ uid</p>
+ </li>
+
+ <li>
+ <p>improve thread lock in <code>lib_trace.c</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>flushinp</code> to use file descriptors in
+ <code>SCREEN</code>, rather than from <code>TERMINAL</code>,
+ and check if they are for a terminal, like SVr4</p>
+ </li>
+
+ <li>
+ <p>modify <code>mcprint</code> to use file descriptor in
+ <code>SCREEN</code>, for consistency</p>
+ </li>
+
+ <li>
+ <p>modify internal function <code>_nc_read_file_entry</code>
+ to show relevant filename in warnings</p>
</li>
<li>
- <p>modify <tt>wnoutrefresh</tt> to call <tt>pnoutrefresh</tt>
- if its parameter is a pad, rather than treating it as an
- error, and modify new_panel to permit its window-parameter to
- be a pad</p>
+ <p>improve checks in internal function
+ <code>convert_string</code> for corrupt terminfo entry</p>
</li>
<li>
- <p>modify curses_trace() to show the trace-mask as symbols,
- e.g., <tt>TRACE_ORDINARY</tt>, <tt>DEBUG_LEVEL(3)</tt>.</p>
+ <p>review/improve handling of out-of-memory conditions</p>
</li>
<li>
- <p>improve checks for valid mouse events when an intermediate
- mouse state is not part of the mousemask specified by the
- caller</p>
+ <p>limit delays to 30 seconds, i.e., padding delays in
+ terminfo, as well as <code>napms</code> and
+ <code>delay_output</code> functions</p>
</li>
<li>
- <p>allow extended-color number in <em>opts</em> parameter of
- <tt>wattr_on</tt>.</p>
+ <p>fix reallocation loop for <code>vsnprintf</code> in
+ <code>_nc_sprintf_string</code> by copying the va_list
+ variable</p>
</li>
<li>
- <p>improve <tt>_tracecchar_t2</tt> formatting of
- base+combining character.</p>
+ <p>modify <code>delscreen</code> to limit the windows which
+ it creates to just those associated with the screen</p>
</li>
<li>
- <p>trim out some unwanted linker options from ncurses*config
- and .pc files seen in Fedora 36+.</p>
+ <p>modify <code>endwin</code> to return an error if it is
+ called again without an intervening screen update</p>
</li>
<li>
- <p>improve shell-scripts with <em>shellcheck</em></p>
+ <p>modify <code>wenclose</code> to handle pads</p>
</li>
<li>
- <p>improve use of "trap" in shell scripts, using a
- script.</p>
+ <p>eliminate use of <code>PATH_MAX</code> in
+ <code>lib_trace.c</code></p>
</li>
<li>
- <p>modify <tt>make-tar.sh</tt> scripts to make timestamps
- more predictable.</p>
+ <p>provide for any <code>CCHARW_MAX</code> greater than 1</p>
</li>
</ul>
<ul>
<li>
- <p>modify <tt>misc/gen-pkgconfig.in</tt> to allow for the
- case where the library directory does not yet exist, since
- this is processed before doing an install</p>
+ <p>correct loop termination condition in
+ <code>waddnstr</code> and <code>waddnwstr</code></p>
+ </li>
+
+ <li>
+ <p>improve parsing in internal function
+ <code>_nc_msec_cost</code>, allowing a single decimal
+ point</p>
</li>
<li>
- <p>set trailing null on string passed from <tt>winsnstr</tt>
- to <tt>wins_nwstr</tt>.</p>
+ <p>amend parameter check for entire string versus specific
+ length in <code>winsnstr</code> and <code>wins_nwstr</code>
+ to match Solaris; make similar correction to
+ <code>wins_nwstr</code></p>
</li>
<li>
- <p>modify <tt>waddch_literal</tt> to allow for double-width
- base character when merging a combining character</p>
+ <p>correct internal function <code>wadd_wch_literal</code>
+ when adding a non-spacing character to a double-width

<h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
bug-fixes</a></h3>
- <p>While there were many bugs fixed during development of ncurses
- 6.4, only a few (the reason for this release) were both important
- and interesting. Most of the bug-fixes were for local issues
- which did not affect compatibility across releases. Since those
- are detailed in the <a href=
- "@HOMEPAGE@/NEWS.html#t20221231">NEWS</a> file no elaboration is
- needed here.</p>
+ <p>The changes to <tt>tparm</tt>, <tt>tgoto</tt> which improve
+ the design of the low-level interfaces are <em>interesting</em>,
+ but are not bug-fixes <em>per se</em>.</p>
+
+ <h3><a name="h3-config-config" id=
+ "h3-config-config">Configuration changes</a></h3>
+
+ <h4><a name="h4-config-major" id="h4-config-major">Major
+ changes</a></h4>
- <p>The interesting bugs were those dealing with memory leaks and
- buffer overflows. Although the utilities are designed for
- <em>text</em> files (which they do properly), some choose to test
- them with <strong>non-</strong><em>text</em> files.</p>
+ <p>These are the major changes (aside from introducing <a href=
+ "#h4-new-library"><tt>tiparm_s</tt></a>):</p>
<ul>
<li>
- <p>Text files contain no embedded nulls. Also, they end with
- a newline. Feeding <strong>tic</strong> non-text files
- exposed a few cases where the program did not check for those
- issues. As a result, further processing of the input found
- limit-checks whose assumptions were invalid.</p>
+ <p>use wide-character (ncursesw) by default</p>
</li>
<li>
- <p>Fixing the limit-checks (first) found a problem with
- <strong>tic</strong> managing the list of strings in a
- terminal description. In merging two terminal descriptions
- (i.e., the “use=” feature), <strong>tic</strong>
- was not allocating a complete copy. A quick repair for that
- introduced a memory leak.</p>
+ <p>use opaque typedefs by default</p>
</li>
+ </ul>
+ <p>However, most of the work on configure scripts was done to
+ reduce warnings within the configure script:</p>
+
+ <ul>
<li>
- <p>The checks for non-text files are improved (i.e., embedded
- nulls in the input file will cause <strong>tic</strong> to
- reject it rather than attempting to process it).</p>
+ <p>intrusive warnings from GNU grep regarding fgrep and
+ egrep</p>
</li>
<li>
- <p>The string allocations in <strong>tic</strong> are
- likewise improved.</p>
+ <p>fatal errors in compile-checks, arising from recent
+ “Modern C” efforts by some developers which
+ caused longstanding configure checks to fail.</p>
+
+ <p>After repairing the configure script, none of that
+ activity affected ncurses because stricter warnings are used
+ routinely in development.</p>
</li>
</ul>

+ in alloc_entry.c, alloc_type.c and hardscroll.c, overlooked
+ due to compiler changes in recent OpenBSD releases</p>

+ </li>
+
+ <li>
+ <p>trim a space after some "-R" options, fixing builds for
+ applications built using clang and ncurses on Solaris</p>
+ </li>
- <p>There are no major changes. No new options were added. Several
- improvements were made to configure checks.</p>
+ <li>
+ <p>work around misconfiguration of MacPorts gcc13, which
+ exposes invalid definition of <tt>MB_LEN_MAX</tt> in gcc's
