+<h2>Release 5.4.0</h2>
+<ul>
+<li>We now test against, and package with, Python 3.10.4.</li>
+<li>New EDDN schema <code>fssbodysignals</code> is now supported.</li>
+<li>Odyssey Update 12 will add <code>BodyID</code> to <code>CodexEntry</code> journal events, so don't
+overwrite this with an augmentation if it is already present.  We've also
+added the same for <code>BodyName</code> in case Frontier ever add that.</li>
+<li>
+<a href="https://github.com/EDCD/EDMarketConnector/issues/24">Translations</a> updated.
+Thanks again to all the contributors.</li>

+<ul>
+<li>Cross-check the <code>MarketID</code> in CAPI data, not only the station name, to ensure
+the data is for the correct station.  Closes <a href="https://github.com/EDCD/EDMarketConnector/issues/1572">#1572</a>.</li>
+<li>Location cross-check paranoia added to several EDDN message types to ensure
+no bad data is sent.</li>
+<li>Ensure we don't send bad BodyID/Name for an orbital station if the player
+uses a taxi.
+Closes <a href="https://github.com/EDCD/EDMarketConnector/issues/1522">#1522</a>.</li>

+<ul>
+<li>Odyssey Update 12 adds a new Journal event, and file, <code>FCMaterials.json</code>,
+detailing the available trades at a Fleet Carrier's bar tender.  Support has
+been added for this.  Plugin developers are sent an <code>FCMaterials</code> event
+with the full contents of the file.</li>
+</ul>
+<h2>
+<a id="user-content-edmcexe" class="anchor" href="#edmcexe" aria-hidden="true"><span aria-hidden="true" class="octicon octicon-link"></span></a>EDMC.exe</h2>
+<p>This now uses specific exit codes in all cases, rather than a generic
+<code>EXIT_SYS_ERR</code> (6) for some cases.  See the appropriate line in EDMC.py for
+details.</p>
+
+
 <h2>Release 5.3.4</h2>
 <p>Whilst EDMarketConnector.exe was fixed for the Odyssey Update 11 difference in Journal file names, EDMC.exe was not.   If you're wondering, that's the command-line utility that, for instance, Trade Computer Extensions uses to obtain data.</p>
