April 2025 monthly summary for curl/curl focusing on MQTT keep-alive improvements and overall reliability. Delivered a new MQTT Keep-Alive Ping Mechanism to maintain connections during idle periods by sending pings at a defined upkeep interval. Integrated into the existing curl MQTT handling stack with attention to low overhead and backward compatibility. This work enhances stability for MQTT workloads and reduces idle-disconnect risk, delivering concrete business value.
