  187    Call to deprecated function file_default_scheme():
         in drupal:8.8.0 and will be removed from drupal:9.0.0. Use

  222    Call to deprecated method strlen() of class Drupal\Component\Utility\Unicode:
         in Drupal 8.6.0, will be removed before Drupal 9.0.0. Use

  16     Class Drupal\pathologic\Tests\PathologicTest extends deprecated class Drupal\simpletest\WebTestBase:
         in Drupal 8.8.0 and will be removed before Drupal 9.0.0. Instead,
         use \Drupal\Tests\BrowserTestBase. See https://www.drupal.org/node/3030340.

  279    Call to deprecated method checkPlain() of class Drupal\Component\Utility\SafeMarkup:
         Will be removed before Drupal 9.0.0. Rely on Twig's
         auto-escaping feature, or use the @link theme_render #plain_text @endlink
         key when constructing a render array that contains plain text in order to
         use the renderer's auto-escaping feature. If neither of these are
         possible, \Drupal\Component\Utility\Html::escape() can be used in places
         where explicit escaping is needed.

  297    Call to deprecated function entity_create():
         in Drupal 8.0.x, will be removed before Drupal 9.0.0. Use
         The method overriding Entity::create() for the entity type, e.g.
         \Drupal\node\Entity\Node::create() if the entity type is known. If the
         entity type is variable, use the entity storage's create() method to
         construct a new entity:
