Dear community, here comes the July community roundup!

July saw the Apache DolphinScheduler community maintain high-energy iteration, with several core modules receiving important fixes and enhancements. In Kubernetes environments, we resolved the issue where PodIP changes prevented reconnection to ZooKeeper, while dependency tasks, variable pools, COS resource management, and more all gained critical fixes that boost overall stability and availability.

On performance and usability, we eliminated the global task-scheduling wait queue, streamlined Master-node parameters, optimized UI presentation logic, and improved both documentation and CI workflows—further lowering the cost of use and operations.

🫶 A big thank-you to this month’s contributors; your meticulous collaboration has driven a marked leap in release quality and energized both the community and technological progress.
