+<h2>Release 4.0.1.0</h2>
+<p>This fixes a bug with the EDDB 'System Provider' URLs.</p>
+<ul>
+<li>It was possible to pick up, and use, a bad SystemAddress from the Frontier
+CAPI.  The CAPI will no longer be used as a source for this.</li>
+<li>If we do not yet have a SystemAddress from the Journal we will use the
+SystemName instead.  This carries the small risk of the player being in one
+of the duplicate-name systems, in which case EDDB might not display the
+correct system.</li>
+</ul>
