+
+Deprecated options have been removed:
+
+| namespace                | removed     | replaced by        |
+|--------------------------|-------------|--------------------|
+| `default_commit_options` | `fsync`     | `j`                |
+| `default_commit_options` | `safe`      | `w`                |
+| `connections.*.options`  | `fsync`     | `journal`          |

+must be done for each document manager. The parameters `doctrine_mongodb.odm.cache.memcached_*`
+and `doctrine_mongodb.odm.cache.redis_*` are not read anymore.
