Automated Workflow Version Updater and Notifier

This n8n workflow automates the process of checking, updating, and notifying about outdated nodes within other workflows. Designed for developers and administrators managing multiple workflows, it ensures all workflows stay current with the latest node versions. The process begins with an external trigger, retrieving specific workflows by ID, then analyzes each workflow for outdated nodes. If outdated nodes are found, the workflow prepends a symbol to their names and optionally adds new nodes to the canvas for easier visualization. It also updates the workflow JSON with the latest node versions. Once modifications are complete, the workflow sends an email summary listing affected workflows and URLs for quick access, facilitating efficient review and update of workflows. This automation is especially useful for maintaining consistency across multiple workflows in complex n8n environments, reducing manual effort and minimizing errors.
