+## Upgrade Notes
+### Difference in scale down behavior during aborts
+
+The v1.1 `abortScaleDownDelaySeconds` feature now allows users full control over the scaling
+behavior of the canary/preview ReplicaSet during an abort. Previously in v1.0, it was not possible
+to affect this behavior. As part of this feature, v1.1 also fixes some inconsistencies in behavior
+with respect to abort scale down.
+
+The most notable change is that upon an abort, the blue-green preview ReplicaSet in v1.1 will now
+scale down 30 seconds after the abort, whereas in v1.0 the preview ReplicaSet was left running
+indefinitely (without any option to scale it down). If you prefer the v1.0 behavior, you can set
+`abortScaleDownDelaySeconds: 0`, which will leave the preview ReplicaSet running indefinitely
+on abort:
+
+```yaml
+spec:
+  strategy:
+     blueGreen:
+       abortScaleDownDelaySeconds: 0
+```
+
+Please read the full
+[documentation](https://argoproj.github.io/argo-rollouts/features/scaledown-aborted-rs/) to understand
+the differences in canary/preview scaling behavior for aborted Rollouts from v1.0 to v1.1.
