+    <p><app>Games</app> has received some performance improvements this release.
+    Search results now show up in the overview search interface, making it
+    faster than ever to start playing your favorite game. With support for
+    collections, you can organize games into groups for easy access or simply 
+    use the built-in <gui>Favorites</gui> and <gui>Recent</gui> collections.
+    <app>Games</app> now supports Nintendo 64 games as a result of some
+    improvements to <sys>libretro</sys>. Finally, <app>Games</app> is more
+    stable now, running games in a secondary process. If a game or emulator
+    crashes now, the main application won't.</p>
