Apr 1, 2026

April 2026 monthly summary for inngest/inngest focused on delivering real-time capabilities, reliability fixes, and onboarding improvements. Key features include Dur able Endpoints Streaming that enables real-time data streaming from an app's SDK handler through the Inngest server to clients, introducing new streaming APIs and Redis-backed publish/subscribe messaging to support scalable, low-latency data flows. A WebSocket acknowledgment race condition fix addresses concurrency issues in worker request handling, adds logging for unknown request IDs, and ensures acknowledgment channels do not block the message processing loop, improving throughput and reliability. The Application Synchronization API provides a robust endpoint to synchronize applications via a specified URL with validation and strong error handling to simplify onboarding and improve reliability. These efforts collectively enhance business value by enabling real-time integrations, reducing failure modes in streaming paths, and improving developer onboarding.
