+#### New Setting: Configurable S3 Object Ownership
+
+S3 Object Ownership is an Amazon S3 bucket-level setting that you can use to control ownership of objects uploaded to your bucket and to disable or enable [access control lists (ACLs).](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html)  By default, Object Ownership is set to the Bucket owner enforced setting and all ACLs are disabled. When ACLs are disabled, the bucket owner owns all the objects in the bucket and manages access to data exclusively using access management policies.
+
+A new setting has been introduced to provide more control over S3 Object Ownership when storing files in an S3 bucket. Previously, the default ACL was set to private, which could lead to access control limitations in certain configurations. This update allows users to select from various ACL options to better manage permissions.
+
