+<h2>Release 4.2.1</h2>
+<p>This is a bug-fix release.</p>
+<ul>
+<li>
+<p>Updated translations.  Thanks once again to all those contributing as per
+<a href="https://github.com/EDCD/EDMarketConnector/wiki/Translations">Translations</a>.</p>
+</li>
+<li>
+<p>PLUGINS.md: Clarify when <code>CargoJSON</code> is populated.</p>
+</li>
+<li>
+<p>macOS: <code>pip install -r requirements.txt</code> will now include <code>pyobjc</code> so that
+running this application works at all.  Check the updated <a href="https://github.com/EDCD/EDMarketConnector/wiki/Running-from-source">Running from
+source</a>
+for some advice if attempting to run on macOS.</p>
+</li>
+<li>
+<p>JournalLock: Handle when the Journal directory isn't set at all, rather than
+erroring.  Fixes <a href="https://github.com/EDCD/EDMarketConnector/issues/910">#910 - Not launching (Linux)</a>.</p>
+</li>
+<li>
+<p>Extra logging added to track down cause of <a href="https://github.com/EDCD/EDMarketConnector/issues/909">#909 - Authentication not possible (PC)</a>
+. The debug log file might now indicate what's wrong, or we might need
+you to run</p>
+<pre><code>"c:\Program Files (x86)\EDMarketConnector/EDMarketConnector.exe" --trace
+</code></pre>
+<p>in order to increase the log level and gather some extra information.
+Caution is advised if sharing a <code>--trace</code> log file as it will now contain
+some of the actual auth data returned from Frontier.</p>
+</li>
+<li>
+<p>Ensure that 'Save Raw Data' will work.  Fixes <a href="https://github.com/EDCD/EDMarketConnector/issues/908">#908 - Raw export of CAPI data broken</a>.</p>
+</li>
+<li>
+<p>Prevent EDDN plugin from erroring when we determine if the commander has
+Horizons.  Fixes <a href="https://github.com/EDCD/EDMarketConnector/issues/907">#907 - Modules is a list not a dict on damaged stations</a></p>
+</li>
+</ul>
