[machine-controller-manager-provider-openstack]

⚠️ Breaking Changes

[OPERATOR] Support for migration of machineClass is dropped by the mcm-provider (gardener/machine-controller-manager-provider-openstack#89, @kon-angelo)

[USER] node field is removed from machine status. controller will now depend on the node label which already was present in the machine object's metadata. If you(or your controller) are dependent on the status.node field of the machine object, then kindly use node label under .metadata.labels (gardener/machine-controller-manager#745, @rishabh-11)

[USER] MachineDeployment would now have Progressing condition even when no progress Deadline is specified. This condition would never go to the reason ProgressDeadlineExceeded in that case. (gardener/machine-controller-manager#762, @himanshu-kun)
[OPERATOR] Using kubectl get machines will display Node of the corresponding machine as a column. If -owide flag is used then the corresponding ProviderID will also be displayed. (gardener/machine-controller-manager#746, @rishabh-11)
[OPERATOR] Added new short names for machine(mc), machineClass(mcc), machineDeployment(mcd), and machineSet(mcs) resources. (gardener/machine-controller-manager#749, @rishabh-11)

[USER] Fix a bug in the bootstrap token creation that caused node to not be able to join the cluster due to an expired bootstrap token. (gardener/machine-controller-manager#777, @himanshu-kun)
[USER] An edge case where all the machineSets were scaled down to zero has been dealt with. (gardener/machine-controller-manager#804, @himanshu-kun)

[USER] Updated golang version to v1.19.2 (gardener/machine-controller-manager#753, @rishabh-11)
[USER] If during a rolling update scale-up is done, MCM scales up only the new machineSet, while in case of scale-down the scale-down amount is split among old machineSets, in proportion to their sizes. (gardener/machine-controller-manager#765, @himanshu-kun)
[DEVELOPER] go version updated to 1.19.4 in pipeline and Dockerfile (gardener/machine-controller-manager#766, @himanshu-kun)
