Import Containers created without a retentionPolicy now expire automatically 72 hours after creation. Previously, omitting retentionPolicy meant the container did not expire until you deleted it manually. The expiresAt field indicates when the container and its Import Operations will be removed. If you relied on long-lived containers without a policy, set a TimeToLiveRetentionPolicy when creating the Import Container. For guidance on organizing containers effectively, see Import API best practices.

Following feedback gathered during the public beta phase, retention policy types and fields are now generally available. For more information, see Import Containers.
