• [OPERATOR] Allow migration to continue when ProviderMachineClass is missing but MachineClass with the same name as ProviderMachineClass is found. Updates Machine object references to the MachineClass. (gardener/machine-controller-manager#559, @prashanth26)
• [OPERATOR] Use cache-based listers to GET the machine-object while reconciling. (gardener/machine-controller-manager#558, @hardikdr)

• [OPERATOR] Adapted integration tests to handle possibly orphaned resources. (gardener/machine-controller-manager#550, @hardikdr)
• [OPERATOR] OOT: Fixes drain timeout issues on retires (gardener/machine-controller-manager#548, @prashanth26)
• [OPERATOR] NetworkUnavailable nodeCondition added to the example, some CNI will update this condition depending on the state of the CNI or the network availability. (gardener/machine-controller-manager#543, @rewiko)
• [OPERATOR] Added a more comprehensive set of events to trigger machine class reconciliations. (gardener/machine-controller-manager#531, @prashanth26)
• [OPERATOR] Finalizers are added by default for all machine class objects. (gardener/machine-controller-manager#531, @prashanth26)
• [OPERATOR] Bootstrap token injection now works in the new OOT Machine controller (gardener/machine-controller-manager#521, @zuzzas)
• [OPERATOR] Add support for ServerGroups in the Openstack driver. VMs can now be created in the ServerGroup specified in the respective MachineClass. (gardener/machine-controller-manager#511, @kon-angelo)
• [OPERATOR] Bugfix: Consider CSI PersistentVolumes during the eviction of Pods with PersistentVolumes. (gardener/machine-controller-manager#509, @ialidzhikov)
• [DEVELOPER] Adds a new phase CrashLoopBackOff that is set due to machine creation failures. (gardener/machine-controller-manager#525, @hardikdr)
• [DEVELOPER] The field availabilitySets in the AzureMachineClass is now deprecated in favour of the field machineSet, which allow to configure AvailabilitySets and VirtualMachineScaleSet Orchestration Mode VM (VMO). The field will be removed in the future. (gardener/machine-controller-manager#519, @dkistner)
