 4. `ManagedDependentResourceContext` has been renamed to `ManagedWorkflowAndDependentResourceContext` and is accessed
    via the accordingly renamed `managedWorkflowAndDependentResourceContext` method.
 5. `ResourceDiscriminator` was removed. In most of the cases you can just delete the discriminator, everything should
     work without it by default. To optimize and handle special cases see the relevant section in [Dependent Resource documentation](/docs/dependent-resources#multiple-dependent-resources-of-same-type).
+6. `ConfigurationService.getTerminationTimeoutSeconds` and associated overriding mechanism have been removed,
+   use `Operator.stop(Duration)` instead.
+7. `Operator.installShutdownHook()` has been removed, use `Operator.installShutdownHook(Duration)` instead
