+
+<h2 id="touch-bar-improvements">Touch Bar improvements</h2>
+
+<p>Touch Bar now supports submenus, and allows mixed icon/text displays using <code>tmenu</code>. When in edit modes (e.g. insert), it will also display an emoji picker as well. See <code>:help touchbar</code> for documentation. <a href="https://github.com/macvim-dev/macvim/issues/1084">#1084</a></p>

+<h1 id="fixes">Fixes</h1>
+
+<ul>
+  <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>
