# Object Lock and Immutability Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO server allows WORM for specific objects or by configuring a bucket with default object lock configuration that applies default retention mode and retention duration to all objects. This makes objects in the bucket immutable i.e. delete of the version are not allowed until an expiry specified in the bucket's object lock configuration or object retention.

* Pod priority and preemption is now enabled by default. Even if you don't plan to use this feature, you might need to take some action immediately after upgrading. In multi-tenant clusters where not all users are trusted, you are advised to create appropriate quotas for two default priority classes, system-cluster-critical and system-node-critical, which are added to clusters by default. `ResourceQuota` should be created to limit users from creating Pods at these priorities...

            // Then
            assertNotNull(defaultBind, "Default constructor should create instance");
            assertEquals(0, defaultBind.getOpnum(), "Default opnum should be 0");
        }

Versioning must be explicitly enabled on a bucket, versioning is not enabled by default. Object locking enabled buckets have versioning enabled automatically. Enabling and suspending versioning is done at the bucket level.
