🐛 Bug Fixes

• [OPERATOR] An issue causing deletion of a legacy (wrongly configured) Shoot cluster to be denied because of network ranges overlapping with the default VPN network is now fixed. (gardener/gardener#​8137, @​oliver-goetz)
• [OPERATOR] Missing permissions were added for the Gardenlet service account for Machine objects. This fix is relevant if feature gate MachineControllerManagerDeployment is enabled in your landscape. (gardener/gardener#​8123, @​gardener-ci-robot)

🏃 Others

• [OPERATOR] Plutono is now updated to v7.5.22 (gardener/gardener#​8100, @​gardener-ci-robot)
• [OPERATOR] Fixed flaky operator behaviour with regards to istio deployment caused by concurrent update of garden object (gardener/gardener#​8105, @​gardener-ci-robot)
• [OPERATOR] The Deploying Shoot namespace in Seed step was slightly improved. Earlier it failed at some occasions when it tried to read zone information for volumes that have not been created yet. This was a transient error that dissolved in subsequent reconcile runs. (gardener/gardener#​8118, @​gardener-ci-robot)
• [OPERATOR] The reconciliation time limit for the controller resource reconciliation, e.g. for ManagedResource, has been increased from 1m to 3m. (gardener/gardener#​8090, @​gardener-ci-robot)
