fix: handle version arrays in node parser for correct version extraction
- Fixed extractVersion to properly handle nodes with version arrays like [1, 1.1, 1.2] - Updated detectVersioned to mark nodes with version arrays as versioned - Added test script to verify version extraction - Gmail Trigger now correctly shows version 1.2 instead of 1 - All 97 nodes with version arrays now show their latest version - Database rebuilt with correct versions for all affected nodes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

## Examples of Version Arrays Found
|
||||
|
||||
Here are some specific examples of version arrays from actual nodes:
|
||||
|
||||
### n8n-nodes-base:
|
||||
- **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)
