MadelineProto Example (now async for huge speed and parallelism!):

if (!file_exists('madeline.php')) {
    copy('https://phar.madelineproto.xyz/madeline.php', 'madeline.php');
}
include 'madeline.php';

$MadelineProto = new \danog\MadelineProto\API('session.madeline');
$MadelineProto->start();

$help.AppChangelog = $MadelineProto->help->getAppChangelog(['device_model' => 'string', 'system_version' => 'string', 'app_version' => 'string', 'lang_code' => 'string', ]);

Or, if you're into Lua:

help.AppChangelog = help.getAppChangelog({device_model='string', system_version='string', app_version='string', lang_code='string', })
