Description: 

As of Symfony 2.2, the official Symfony docs use "path" rather than "pattern" to denote the URL of a route item. Drupal now follows suit. For example:

 aggregator.feed_delete:
  path:  '/admin/config/services/aggregator/delete/feed/{aggregator_feed}'
   defaults:
     _entity_form: 'aggregator_feed.delete'
   requirements:
     _permission: 'administer news feeds'
