🐛 Bug Fixes

• [USER] MCM recognizes scaling-up of machineDeployment from 0 to more replicas as a scaling event rather than a rolling update. by @thiyyakat [#956]
• [USER] A bug has been fixed for draining nodes with provider-unrelated volumes like NFS volumes. With this fix, the machine controller doesn't try to track their (non-existing) VolumeAttachments. by @timebertt [#937]
• [OPERATOR] Fixed a bug in drain logic where volume reattachment context declaration used incorrect parent context by @rishabh-11 [#947]

🏃 Others

• [OPERATOR] MCM will use an informer instead of theclientset to list pods in the drain logic. This will reduce the load on etcd/kube-apiserver. by @thiyyakat [#949]
