- In `Compliance` mode, objects cannot be deleted by anyone until retention period has expired for the given version id. If user has governance bypass permissions, an object's retention date can be extended in `Compliance` mode.
- Once object lock configuration is set to a bucket
  - New objects inherit the retention settings of the bucket object lock configuration automatically
  - Retention headers can be optionally set while uploading objects
