Migration guide - Step Engine

Upgrading from version 2.* to version 3.*

If you’re migrating the StepEngine module from version 2 to version 3, you need to follow the steps described below. In Version 3 the StepCollectionInterface::getPreviousStep() has a new second optional argument (AbstractTransfer $dataTransfer). If you use this interface for your own implementation, you need to update your derived class. If StepEngineInterface::getTemplateVariables() is overridden in your project, you need to update the call to StepCollectionInterface::getPreviousStep() here as well.
