 # Changelog
 
+## 1.40.0
+* Enhancement - Agent's default stats gathering is changing from docker streaming stats to polling. This should not affect the metrics that customers ultimately see in cloudwatch, but it does affect how the agent gathers the underlying metrics from docker. This change was made for considerable performance gains. Customers with high CPU loads may see their cluster utilization increase; this is a good thing because it means the containers are utilizing more of the cluster, and agent/dockerd/containerd are utilizing less [#2452](https://github.com/aws/amazon-ecs-agent/pull/2452)
+* Enhancement - Adds a jitter to this so that we don't query docker for every container's state all at the same time [#2444](https://github.com/aws/amazon-ecs-agent/pull/2444)
+* Bug - Register custom logger before it gets used to ensure that the formatter is initiated before it is loaded [#2438](https://github.com/aws/amazon-ecs-agent/pull/2438)

 ## 1.39.0
