Description: 

\Drupal\Core\EventSubscriber\AcceptNegotiation406 (service ID: accept_negotiation_406) was renamed to \Drupal\Core\EventSubscriber\RenderArrayNonHtmlSubscriber (service ID: renderer_non_html).

This is purely a clarification. This is technically a BC break, but event subscribers are never intended to be used directly: https://www.drupal.org/core/d8-bc-policy#paramconverters.
