 If `managedSecurityGroups: true`, security group rule opening 22/tcp is added to security groups for bastion, controller, and worker nodes respectively. Otherwise, you have to add `securityGroups` to the `bastion` in `OpenStackCluster` spec and `OpenStackMachineTemplate` spec template respectively.

+#### Change to floatingIP
+
+The `OpenStackMachineSpec.FloatingIP` field has moved to `OpenStackClusterSpec.Bastion.FloatingIP`.
+For example, if you had the following `OpenStackMachineTemplate`:
+
+```yaml
+apiVersion: infrastructure.cluster.x-k8s.io/v1alpha6
+kind: OpenStackMachineTemplate
+metadata:
+  name: ${CLUSTER_NAME}-md-0

+      floatingIP: "1.2.3.4"
+```
+
+This will safely converted to use `Bastion.FloatingIP` when upgrading to version 0.8.
+
+To use the new `Bastion.FloatingIP` field, here is an example:

+```yaml

 `securityGroups` has been simplified by the removal of a separate filter parameter. It was previously:
