The View hierarchy of classes is reorganized to include new classes with member functions moved and renamed, to solve defects in the original design: OpenView accumulates raw state and tx changes and can be applied to the base. ApplyView accumulates changes for a single transaction, including metadata, and can be applied to an OpenView. The Sandbox allows changes with the option to apply or throw them out. The PaymentSandbox provides a sandbox with account credit deferral. Call sites are changed to use the class appropriate for the task.
