Convoy v2024.4.1 has been released, offering a range of new features, improvements, and bug fixes, including the introduction of a PostgreSQL-backed rate limiter and RabbitMQ message broker support. Enhancements allow for payload mutation using JavaScript functions for events ingested via message brokers such as Kafka, Amazon SQS, and Google PubSub, enabling greater integration flexibility by allowing existing queues and topics to connect to Convoy without the need for format-specific adjustments. RabbitMQ support, contributed by a GitHub user, expands Convoy's message broker capabilities to include both self-hosted and cloud instances. The transition of the rate limiter from Redis to PostgreSQL is part of a broader move away from Redis. Additionally, API changes include renaming endpoint titles to names and target URLs to URLs, along with the addition of project configurations for enforcing HTTPS endpoints and improved documentation. Bug fixes address issues with telemetry, project settings display, subscription filters, and other functionalities, enhancing overall user experience.
