# 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. ## Patch Releases ### 2.5.1 Released 2025-07-09 ### All Services Metrics and health status endpoints are now available within the ESS cluster on port 9000. ## Changelogs For changelogs, see [2.5 Changelogs](/ess/2.5/releases/changelog.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
