Rqueue 4.0.0-RC4 Release Notes

Release Date: May 2, 2026

Overview

Rqueue 4.0.0-RC4 introduces production-ready NATS JetStream backend support, bringing multi-backend message queue capabilities to Rqueue. This release adds a fully-featured alternative to Redis, enabling users to choose the backend that best fits their infrastructure and requirements.

What's New

🎯 Major Features

🚀 NATS JetStream Backend (NEW)

Complete implementation of a high-performance, cloud-native message broker alternative to Redis:

  • Full Feature Parity: Supports all core Rqueue features including message enqueueing, polling, retry logic, and dead-letter queues
  • Stream-based Architecture: Leverages NATS JetStream for persistent, replicated message storage
  • Cloud-Native Design: Stateless brokers with durable message persistence
  • Horizontal Scalability: JetStream clustering enables distributed deployments

Key Capabilities:

  • Multi-priority queue support via stream multiplexing
  • Configurable consumer settings (ack-wait, max-deliver)
  • Queue name validation and stream descriptions for operational visibility
  • Producer and consumer mode support (enqueue-only or full listener deployment)
