[gardener-extension-provider-openstack]

⚠️ Breaking Changes

• [USER] Extension resource configs (InfrastructureConfig, ControlPlaneConfigs, WorkerConfig) are now deserialized in "strict" mode, including during validation by the admission webhook. This means that resources with fields that are not allowed by the API schema will be rejected by validation. Creating new shoots containing such resources will not be possible, and reconciling existing shoots will fail with an appropriate error until you manually update the shoot to make sure any extension resource configs contained in it are valid. (#253, @stoyanr)
• [OPERATOR] The gardener-extension-validator-openstack Helm chart as well as different assets inside have been renamed to the more general term gardener-extension-admission-openstack. Please consider to take corresponding action if you don't use Helm to manage your deployment in the Garden cluster. (#265, @ialidzhikov)
• [OPERATOR] The Docker image eu.gcr.io/gardener-project/gardener/extensions/validator-openstack will no longer be maintained as of this release in favor of the successor eu.gcr.io/gardener-project/gardener/extensions/admission-openstack. Please consider replacing any references to the image eu.gcr.io/gardener-project/gardener/extensions/validator-openstack by eu.gcr.io/gardener-project/gardener/extensions/admission-openstack. (#265, @ialidzhikov)
