+<p>Most importantly, <a href="#layer-152">layer 152</a> added support for Firebase SMS authentication, which in some conditions may be required by the server in order to send SMS codes.<br>
+Currently, only official apps can make use of Firebase SMS authentication: this means that in some conditions, only the official applications can receive a login/signup code via SMS/call.<br>
+Third-party apps may log in using any of the other code delivery methods (Telegram codes, Fragment codes, email codes, <a href="/api/auth#future-auth-tokens">future auth tokens</a>, <a href="/api/qr-login">QR codes</a>).</p>

 Users may now edit the <a href="/api/bots/info">usernames, name, about text, description and profile picture</a> of bots they own using the API.<br>
 Bots can now directly invoke <a href="/method/photos.updateProfilePhoto">photos.updateProfilePhoto</a> and <a href="/method/photos.uploadProfilePhoto">photos.uploadProfilePhoto</a> to edit their own profile picture.<br>
 Bots may also now specify a custom peer filter when using <a href="/constructor/keyboardButtonSwitchInline">keyboardButtonSwitchInline</a> buttons.</p>
