Undefined function esc() in v4.5.8

with:

Code:

<title><?= esc($title ?? 'Default Title') ?></title>

get error after upgrading:

Code:

PHP Fatal error:  Uncaught Error: Call to undefined function esc() in /var/www/mvc/xa/app/Views/templates/xaHeader.php:7
Stack trace:
#0 {main}
  thrown in /var/www/mvc/xa/app/Views/templates/xaHeader.php on line 7

Any ideas why?

You have updated incorrectly. The function should work correctly. Can you repeat the upgrade step by step or move your code to a clean install?

And please specify the version, 4.6.8 does not exist.
