# ESS 3.3

ESS 3.3 is a minor release of the [Enterprise Solid Server](/ess/3.3/introduction.md). It introduces the Activity Log, a new API for retrieving recent activity on a user's account, and improves the reliability and coverage of audit events.

## What's new in 3.3

**Activity Log** — A new Platform Management API that returns recent activity for an authenticated user's account, presented as [W3C Activity Streams](https://www.w3.org/TR/activitystreams-core/) collections with filtering and cursor-based pagination. Use it to build features such as an in-app activity feed. See [Activity Log](/ess/3.3/services/service-platform-management/activity-log.md) for details.

**Reliable event delivery** — ESS services now publish audit and other events using a transactional outbox: the event is written in the same database transaction as the change it records, then delivered asynchronously with retries. See [Reliable Event Delivery](/ess/3.3/administration/reliable-event-delivery.md) for details.

**New audit events** — Audit events are now emitted for account lifecycle operations and for notification subscription changes, and existing events carry richer context. The **`service-started`** and **`service-shutdown`** events have been removed. See [Auditing](https://docs.inrupt.com/security/auditing/) for the full list.
