Auto-generate GitHub release notes and notify via Slack

Auto-Generate GitHub Release Notes and Notify via Slack (n8n Workflow)

This n8n workflow automates the process of: - Generating structured GitHub release notes from merged pull requests since the last tag. - Creating a draft GitHub release using the latest tag and PR info. - Sending a formatted summary to a Slack channel.

All of this is triggered manually via a form, where the user inputs the repository, owner and target branch.

Who's It For

This flow is perfect for: - Open-source maintainers looking to automate changelog management. - DevOps engineers handling release cycles. - Engineering teams maintaining structured, consistent GitHub releases. - Technical writers who prepare release notes.
