You can change the release note to : "Drain timeout is now correctly honored for Pod eviction during Machine Drain" ?

Can you do a test of this with some short timeouts and Pods with large number of PVs to see if there are no surprises ?

Performed the testing, the context cancellation leads to force delete even if pod with PVs are in process of eviction.
