Renovate Configuration Fix

🐛 Problem

Renovate updated dependencies that caused conflicts:

• React was updated to v19, but Grafana requires React v18
• Grafana packages were updated to v12, breaking React v18 compatibility

🔧 Solution

Updated renovate.json to:

React Constraints:

• Block React v19 updates entirely
• Keep React ecosystem at v18.x only
• Prevent major version bumps for React packages

Grafana Constraints:

• Keep Grafana packages at v10.x for React 18 compatibility
• Require manual review for Grafana updates

📋 Configuration Added:

{
  "groupName": "React ecosystem",
  "allowedVersions": "^18.0.0",
  "description": "Keep React at v18 for Grafana compatibility"
},
{
  "groupName": "Grafana packages", 
  "allowedVersions": "^10.0.0",
  "description": "Keep Grafana packages at v10 for React 18 compatibility"
},
{
  "matchPackageNames": ["react", "react-dom"],
  "matchUpdateTypes": ["major"],
  "enabled": false,
  "description": "Block React 19 - incompatible with Grafana"
}

✅ Next Steps:

1. Commit this fix
2. Close/rebase the failing Renovate PR
3. Renovate will respect the new constraints going forward

🔍 Monitoring

• Check Renovate PRs don’t propose React 19
• Ensure Grafana packages stay at v10.x
• Review dependency conflicts before merging
