Description: 

The method Drupal\Core\Template\Attribute::merge() is deprecated. Use Drupal\Core\Template\Attribute::mergeAttribute() instead.

The two functions are identical except for the parameter type. The new ::mergeAttribute() method declares the interface Drupal\Component\Utility\HtmlAttribute\AttributeInterface for its parameter; the old ::merge() method declares Drupal\Core\Template\Attribute.
