+<li>Outcome.Experimental has had C representation support since the beginning, however it had
+been mainly intended that C++ would originate Results, they would pass through C, and back
+into C++. It hadn&rsquo;t really been expected that C would want to do much with Results other than
+inspect them for happy or sad path.</li>
+</ul>
+
+<p>It turns out there is more demand than expected for a more functional Result from within C,
+so this release adds the power to create Results in success and two types of failure, semantic
+comparison of Results, and printing of Result messages. You can also wrap a C enum into a
+quick status code from enum, allowing easy custom C error coding from 100% within C.</p>
