Currently running Enfold 4.5.6.1-beta-1 – theme update

Dear support

we are currently running 4.5.6.1-beta-1 –> we now noticed some issues

1. is it possible for us to update to current version Version 4.5.7 without loosing any fix from the given beta?
2. automatic update is not finding the current version (see attached image)

3. we are using custom post types with correct integration in our functions.php

function my_alb_supported_post_types( array $supported_post_types )
{
  $supported_post_types[] = 'mitarbeiter';
  $supported_post_types[] = 'munkatarsaink';
  $supported_post_types[] = 'infothekbeitrag';
  $supported_post_types[] = 'cikk';
  $supported_post_types[] = 'partner';
  $supported_post_types[] = 'partnereink';
  $supported_post_types[] = 'referenzbericht';
  $supported_post_types[] = 'referencia-nyilatkozat';
  $supported_post_types[] = 'layout_inhalt';
  $supported_post_types[] = 'jobboerse';
  $supported_post_types[] = 'allaslehetosegek';
  $supported_post_types[] = 'referenz';
  $supported_post_types[] = 'referencia';
  $supported_post_types[] = 'erp_loesung';
  $supported_post_types[] = 'wiki';
  $supported_post_types[] = 'text-blocks';
  $supported_post_types[] = 'events';
  $supported_post_types[] = 'berufsgruppe';
  $supported_post_types[] = 'digitale_arbeitswelt';
  $supported_post_types[] = 'faq';
	
  return $supported_post_types;
}
add_filter('avf_alb_supported_post_types', 'my_alb_supported_post_types', 10, 1);

we noticed that no one of our custom post types has the integration of “layout box” (sidebar,header,footer,etc) –> is anything missing in our code?

Thanks for your advice Marc
