n8n has introduced two new features, data pinning and data mapping, to enhance workflow testing and setup. Data pinning allows users to save and reuse the output data of a node, reducing the need to repeatedly fetch new data from external systems, which can conserve time and resources, especially when working with systems that have usage limits. This ensures consistent data across workflow tests, providing reliability and efficiency. The data mapping feature streamlines the process further by enabling users to drag and drop data sets from one node to another, automatically generating the necessary expressions. These innovations aim to simplify automation and low-code processes for users.
