Change record status: 
Introduced in branch: 
2.1.x
Introduced in version: 
2.1.0
Description: 

The method \Drupal\node_revision_delete\NodeRevisionDeleteInterface::getPreviousRevisions() is deprecated. You should use \Drupal\node_revision_delete\NodeRevisionDeleteInterface::getPreviousRevisionIds() instead. The module no longer loads all previous revisions as this can cause out-of-memory errors. Code that uses getPreviousRevisions() should be refactored to prevent against unbound entity revision loading.
