MCM will deploy new machines into the given subnet by pre-allocating Neutron ports and pass them to the Nova server object. (gardener/machine-controller-manager#545, @MrBatschner)
• [USER] The machine-controller-manager supports now machines attached to Azure VirtualMachineScaleSet Orchestration Mode VM (VMO). (gardener/machine-controller-manager#519, @dkistner)
• [USER] Restored tag verification in the Azure driver to filter VMs/disks/NICs based on tags (gardener/machine-controller-manager#507, @zuzzas)
• [OPERATOR] An issue causing panic when the encoded machine template hash length is less than expect limit is now fixed. (gardener/machine-controller-manager#577, @AxiomSamarth)
• [OPERATOR] Set Machine Phase to Terminating before draining. (gardener/machine-controller-manager#564, @prashanth26)
• [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] OOT: Enqueue machine only when node conditions have changed. (gardener/machine-controller-manager#557, @prashanth26)
• [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)

📰 Noteworthy

• [USER] NetworkUnavailable node condition is also considered by default while considering the machine's to be unhealthy. (gardener/machine-controller-manager#543, @rewiko)
• [USER] AWS: Allows deletion of machines even on modify instance call failure (gardener/machine-controller-manager#515, @prashanth26)
• [OPERATOR] Machine force deletion computation is based on deletionTimestamp instead of LastUpdatedTimestamp. (gardener/machine-controller-manager#564, @prashanth26)
• [OPERATOR] OOT: Introduced a backoff in re-enqueuing machines on creation/deletion failures. Avoids throttling APIServer & provider calls. (gardener/machine-controller-manager#557, @prashanth26)
