 <ul>
-  <li>New “Appearance” option pane (accessible via “⌘,” or MacVim → Preferences) to allow customizing how MacVim looks. Users can now select how MacVim works with Dark Mode, and configure titlebar to be hidden or transparent. <a href="https://github.com/macvim-dev/macvim/issues/912">#912</a> <a href="https://github.com/macvim-dev/macvim/issues/1038">#1038</a> <a href="https://github.com/macvim-dev/macvim/issues/1056">#1056</a>

-  <li>MacVim localization support. It now uses translated Vim messages for the specified locale. See <code>:help multilang-messages</code> to see how to configure it. <a href="https://github.com/macvim-dev/macvim/issues/991">#991</a>
-<img width="450" alt="localization screenshot" src="https://user-images.githubusercontent.com/1217449/90110395-ff878a00-dd01-11ea-8207-a8c6b250c4dd.png" /></li>
+  <li>Window menu no longer shows duplicate “Enter Full Screen” or “Tile Window to Left of Screen” entries whenever the user switches among different MacVim windows. <a href="https://github.com/macvim-dev/macvim/issues/566">#566</a> <a href="https://github.com/macvim-dev/macvim/issues/992">#992</a></li>
+  <li>Fix issue where going to full screen mode when titlebar appearance is set to “hidden” would result in lost focus of the window. <a href="https://github.com/macvim-dev/macvim/issues/1078">#1078</a></li>
+  <li>The password dialog box when using <code>:!sudo</code> or other commands that require password entry (<code>macvim-askpass</code>) will no longer focus on Finder, and will keep the focus on MacVim. <a href="https://github.com/macvim-dev/macvim/issues/1091">#1091</a></li>
+  <li>Fix minor wrong tooltip in the “Appearance” preference pane. <a href="https://github.com/macvim-dev/macvim/issues/1087">#1087</a></li>
+  <li>“General” preference pane will now be correctly sized when Sparkle updater is disabled (e.g. Homebrew builds). <a href="https://github.com/macvim-dev/macvim/issues/1089">#1089</a></li>
+  <li>Misc issues were fixed by Vim upstream, e.g. <code>vimgrep</code> causing a crash, and odd behaviors with using Shift-O on the first line. <a href="https://github.com/macvim-dev/macvim/issues/1082">#1082</a> <a href="https://github.com/macvim-dev/macvim/issues/1083">#1083</a></li>

-<p>Fixes:</p>
-
-<ul>
-  <li>Fix mvim:// protocol handler behavior. Reverts behavior back to old behavior (before snapshot-162), but add new fallback handling to try to handle poorly formed URLs that don’t double-encode special characters. See <code>:help macvim://</code>. <a href="https://github.com/macvim-dev/macvim/issues/1055">#1055</a></li>
-  <li>Can now change tabs using menu and keyboard shortcuts (⌘{ / ⌘} / ⌘T) when in terminal mode. <a href="https://github.com/macvim-dev/macvim/issues/1045">#1045</a></li>
-  <li>Fix crash during MacVim launch in Snapshot 164 (8.2.1424) due to dynamic library linkage. <a href="https://github.com/macvim-dev/macvim/issues/1073">#1073</a></li>
