Jan 1, 2025

January 2025 (2025-01): Delivered a critical compatibility upgrade for the quarkus-test-framework by aligning Strimzi Kafka operator with the latest releases. Upgraded Strimzi operator to 0.45.0 and Kafka to 3.9.0 across configuration and build artifacts to preserve compatibility (Strimzi no longer supports Kafka 3.7.0). Updated POMs, YAML files, and KafkaVendor enum, and container version to 0.109.1. This change reduces runtime risk, ensures future-proof testing environments, and stabilizes streaming test scenarios with current operator versions. Commit: 6f3afd1eece47f54d058d1eca2d6af9b12e0.
