Thanks the summary. Does the entry below look ok?
<li>Support has been added for the AArch64 MinGW target
(<code>aarch64-w64-mingw32</code>). At present, this target
supports C and C++ for base Armv8-A, but with some caveats:
<ul>
<li>Although most variadic functions work, the implementation
of them is not yet complete.
</li>
<li>C++ exception handling is not yet implemented.</li>
</ul>
Further work is planned for GCC 16.
</li>
