+      <description>
+        <p>In the newest version, when launching the app, you will get a welcome page that lets you choose which account you want to use and lets you log in to other accounts. The welcome screen will also warn you when NeoChat cannot load an account.</p>
+        <p>NeoChat will also let you register a new account directly from the app itself. Deactivating your Matrix account is also possible from within NeoChat.</p>
+        <p>Spaces are a relatively new feature of Matrix that let you group chat channels together. This is used to improve the discoverability of rooms, manage large communities, or just tidy all the channels you are in. You can now do all this without leaving NeoChat.</p>
+        <p>NeoChat won't let you miss any new notifications anymore. We added a new page that includes all your recent notifications and when NeoChat is closed, you will still be able to receive push notifications. The main timeline will let you know when more messages are loading and when you reach the end of it.</p>
