The .remove() and .removeOne() bulk find ops are deprecated now (i.e. https://docs.mongodb.com/manual/reference/method/Bulk.find.remove/ and https://docs.mongodb.com/manual/reference/method/Bulk.find.removeOne/ ). They are replaced by functionally equivalent .delete() and .deleteOne() methods. .remove() and .removeOne() are only turned into aliases for those. This change was made with the assumption that the documentation for the new methods would be available under https://docs.mongodb.com/manual/reference/method/Bulk.find.delete/ and https://docs.mongodb.com/manual/reference/method/Bulk.find.deleteOne/ , so let us know if that’s not going to be the case.
