### Features
- Objects matching these prefixes will behave as though versioning were suspended. These objects **will not** be replicated if bucket has replication configured.
- Objects matching these prefixes will also not leave delete markers, dramatically reduces namespace pollution while keeping the benefits of replication.
- Objects matching these prefixes will also not leave `null` delete markers, dramatically reduces namespace pollution while keeping the benefits of replication.
- Users with explicit permissions or the root credential can configure the versioning state of any bucket.
