July 2026: Delivered a feature enhancement for Kafka queue splitting by adding optional jq-based message filtering. This enables flexible, JSON-aware filtering of Kafka messages at the queue-splitting boundary, improving routing accuracy and reducing downstream toil. The change maintains backward compatibility by gating the new operator behind the KafkaQueueSplittingWithJqFilter feature, ensuring older operators are unaffected and keeps parity with existing filter support across SQS, GCP Pub/Sub, Azure Service Bus, Redis Pub/Sub, Temporal, and BullMQ. Documentation and schema were updated to reflect the new jq_filter input and its usage across all queue types.
