n8n Workflow Builder

# Release v1.12.1: Bugfix for Change Simulation **Release Date**: 2024-12-16 ## 🐛 Bug Fix ### Missing `list_workflows` Method **Issue**: The `simulate_workflow_changes` and `analyze_change_impact` tools failed with error: ``` AttributeError: 'N8nClient' object has no attribute 'list_workflows' ``` **Root Cause**: The change simulation system calls `n8n_client.list_workflows()` to fetch all workflows for downstream impact analysis, but the N8nClient only had `get_workflows()`. **Fix**: Added `list_workflows()` method as alias to `get_workflows()` in `client.py`: ```python async def list_workflows(self, active_only: bool = False) -> List[Dict]: """Alias for get_workflows - used by change simulation""" return await self.get_workflows(active_only) ``` ## ✅ Affected Tools Now Working - ✅ `simulate_workflow_changes` - Full terraform-style change preview - ✅ `analyze_change_impact` - Multi-dimensional impact analysis Both tools now correctly fetch all workflows to analyze downstream impact. ## 📦 Changes **Modified Files**: - `src/n8n_workflow_builder/client.py` - Added `list_workflows()` alias method ## 🔗 Related Releases - v1.12.0: Change Simulation & Approval System (initial release) --- **Full Changelog**: https://github.com/schimmmi/n8n-workflow-builder/compare/v1.12.0...v1.12.1 **Installation**: ```bash pip install --upgrade n8n-workflow-builder ```
