Release Notes

ESS 2.5.0 Released 2025-06-26

Message Security Enhancement

Encryption for messaging was enhanced with an update to the key derivation algorithms. Existing messages remain fully accessible during a migration of the encryption standard.

Resource Change Notifications

Users and operators can now use the Notification Service HTTPS API to subscribe to notifications from the Storage Service. This is an additive, backwards-compatible change to the released notification subscriptions API. New event types are supported by the Notification Service, and a new authorization mechanism has been added to subscribe to notifications about resources using an Access Grant.

The Storage Service generates events for each of the following:

• A resource is created

• A resource is modified

• A resource is deleted

• A container is created

• A container is modified

• A container is deleted

For more information, see Notification Delivery Service.
