Event Streams Release Notes for September 2026

Event Streams features and fixes are not in the runtime release.

Introduced REST endpoints for consuming messages from Event Streams topics, letting you poll for messages over HTTP. The API automatically acknowledges each message as it's consumed. You can consume a single message at a time or retrieve multiple messages in a batch, depending on the endpoint you call. (ES-3932)
Introduced dead letter routing for Listen operations on Exclusive and Failover subscriptions with transacted acknowledgment, so a repeatedly failing message no longer blocks consumption of rest of the messages from the topic/subscription. Enable Dead Letter Routing to have failed messages routed to DLQ topic after retry limit is reached (ES-4185)
Added Topic, Subscription, and Subscription Type as default Document Properties on the Event Streams connector, so downstream process shapes can reference the actual runtime values without hard-coding them or passing them as message properties. (ES-4199, ES-4264)

Resolved excessive log noise in the ES connector, eliminating repeated FeatureNotSupportedException log entries caused by the recent connector upgrade. (ES-4202)
