• [DEVELOPER] Added migration logic for moving from provider-specific machine class to generic machine classes in out of tree code path. On migration, the machine.sapcloud.io/migrated annotation set on the old machine class. (#484, @prashanth26)
• [DEVELOPER] The machine controller adds finalizer only when machine reference is present, deletes it otherwise. (#484, @prashanth26)

Improvements

• [USER] Retry when secret is referred by machineClass is missing (#495, @AxiomSamarth)
• [USER] Node condition is added to the status of terminating nodes indicating the termination start time and reason (Unhealthy|ScaleDown) (#492, @guydaichs)
• [OPERATOR] All nodes under machine deployments being rolled-out are annotated with cluster-autoscaler.kubernetes.io/scale-down-disabled: "True" during the period of rolling-update. (#496, @hardikdr)
• [OPERATOR] A new command line flag autoscaler-scaldown-annotation-during-rollout is introduced to disable annotating the nodes with cluster-autoscaler annotation cluster-autoscaler.kubernetes.io/scale-down-disabled during rollout. (#496, @hardikdr)

v0.33.0

[machine-controller-manager]

Improvements

• [OPERATOR] Avoids race between secret finalizer creation/deletion between in-tree & OOT controllers (#487, @prashanth26)
• [OPERATOR] Enable finer machine configurations per MachineDeployment/MachineSet/Machines basis. Exposed configurations: MachineDrainTimeout, MachinHealthTimeout, MachineCreationTimeout, MaxEvictRetries, NodeConditions. (#478, @hardikdr)
• [DEVELOPER] Increased default concurrent worker syncs from 5 --> 10 (#491, @prashanth26)

v0.31.0

[machine-controller-manager]

v0.30.0
