**Code**: `version: [1, 2]` - **HTTP Request V3**: `version: [3, 4, 4.1, 4.2]` - **Webhook**: `version: [1, 1.1, 2]` - **Wait**: `version: [1, 1.1]` - **Schedule Trigger**: `version: [1, 1.1, 1.2]` - **Switch V3**: `version: [3, 3.1, 3.2]` - **Set V2**: `version: [3, 3.1, 3.2, 3.3, 3.4]` ### @n8n/n8n-nodes-langchain: - **LM Chat OpenAI**: `version: [1, 1.1, 1.2]` - **Chain LLM**: `version: [1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7]` - **Tool HTTP Request**: `version: [1, 1.1]` ## Summary Total nodes with version arrays: **97 nodes** - From n8n-nodes-base: 65 nodes - From @n8n/n8n-nodes-langchain: 32 nodes These nodes use versioning to maintain backward compatibility while introducing new features or changes to their interface. The version array pattern allows n8n to: 1. Support multiple versions of the same node 2. Maintain backward compatibility with existing workflows 3. Introduce breaking changes in newer versions while keeping old versions functional 4. Use `defaultVersion` to specify which version new instances should use Common version patterns observed: - Simple incremental: `[1, 2]`, `[1, 2, 3]` - Minor versions: `[1, 1.1, 1.2]` (common for bug fixes) - Patch versions: `[3, 4, 4.1, 4.2]` (detailed version tracking) - Extended versions: `[1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7]` (Chain LLM has the most versions)
