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.
