+            <h4>UI changes</h4>
+						<p>Instead of an old-fashioned status bar — an app “chin” — the gear menu and refresh status appear at the bottom of the sidebar, and the current article‘s URL (or mouseover URL) appears at the bottom of the detail view.</p>
+						<p>Feedback is welcome on this change. It might need reversing or refining. Or it might be fine as-is. Let me know what you think.</p>
+
+						<h4>Performance</h4>
+						<p>The time between clicking on a feed — or especially a folder — and when the articles appear in the timeline view has been drastically reduced. This was due to a number of changes. (Thanks to Instruments!)</p>
+						<p>OPML importing was slow — now it’s borderline instantaneous, even with thousands of feeds.</p>
+						<p>HTML metadata parsing is now cached and performed on a background thread.</p>
+
+						<h4>Misc.</h4>
+						<p>Detect and parse RSS feeds that lack an opening rss tag. (See https://www.natashatherobot.com/feed/ as an example.)</p>
+						<p>When the home page of a feed isn’t known yet, base the favicon on the feed URL.</p>
+						<p>Fix a memory leak that happened every time you added a feed.</p>
+						<p>Removed signs of some features that won’t appear until 2.0. (I’ve been doing some punting. It hurts, but that’s how I know I’m doing it right.)</p>
+						<p>Increased spacing in sidebar from small to medium.</p>
+						<p>The smart feeds now appear in a Smart Feeds group in the sidebar.</p>
+
+						<h4>More info</h4>
+						<p>You can always look at the <a href="https://github.com/brentsimmons/Evergreen/commits/master">recent commits on GitHub</a> for more details.</p>
