Generate GitLab release notes from Linear issues with Claude Opus

📝 Release Note Helper

Triggered by a GitLab MR webhook, this workflow automatically assists your team in writing customer-facing release notes by combining Linear issue data with Claude AI.

Apply the rn-release-n8n label to any release note MR in your docs repository to trigger it.

How it works

1. Version detection — reads your release RSS feed to find the last published version, then fetches all matching Linear version labels created since then to determine the version range automatically
2. Issue collection — queries Linear for all completed issues in that version range that have Zendesk tickets, Slack links, or custom labels (Customer request, Release note public) attached
3. Ticket summary — posts a structured list of all relevant issues to the MR as a comment
4. AI draft — sends issue details to Claude, which generates customer-facing changelog entries grouped into ### Enhancements and ### Fixes, posted as a second MR comment
5. Done label — adds rn-done to the MR when complete to prevent re-runs

Setup

1. Configure a GitLab webhook on your docs repo pointing to this workflow's URL (Merge Request events)
2. Create two labels on your GitLab repo: rn-release-n8n (to trigger) and rn-done (auto-applied on completion)
3. Update the RSS Read node URL to your release RSS feed
4. Replace YOUR_PROJECT_ID in all GitLab API nodes with your docs project ID
5. Replace YOUR_WORKSPACE in the Code nodes with your Linear workspace slug
6. Connect Linear API, GitLab API, and Anthropic API credentials

Notes

• Versioning assumes a vX.Y Linear label convention — adapt the Format labels node for your own scheme
• The AI prompt in Message a model is ready to use but can be customised to match your tone and changelog format
• Issues are filtered to those with Zendesk, Slack attachments, or your custom labels — adjust in Set Params
