# 🛠️ Crawl4AI v0.7.1: Minor Cleanup Update
|
||||
|
||||
*July 17, 2025 • 2 min read*
|
||||
|
||||
---
|
||||
|
||||
A small maintenance release that removes unused code and improves documentation.
|
||||
|
||||
## 🎯 What's Changed
|
||||
|
||||
- **Removed unused StealthConfig** from `crawl4ai/browser_manager.py`
|
||||
- **Updated documentation** with better examples and parameter explanations
|
||||
- **Fixed virtual scroll configuration** examples in docs
|
||||
|
||||
## 🧹 Code Cleanup
|
||||
|
||||
Removed unused `StealthConfig` import and configuration that wasn't being used anywhere in the codebase. The project uses its own custom stealth implementation through JavaScript injection instead.
|
||||
|
||||
```python
|
||||
# Removed unused code:
|
||||
from playwright_stealth import StealthConfig
|
||||
stealth_config = StealthConfig(...) # This was never used
|
||||
```
|
||||
|
||||
## 📖 Documentation Updates
|
||||
|
||||
- Fixed adaptive crawling parameter examples
|
||||
- Updated session management documentation
|
||||
- Corrected virtual scroll configuration examples
|
||||
|
||||
## 🚀 Installation
|
||||
|
||||
```bash
|
||||
pip install crawl4ai==0.7.1
|
||||
```
|
||||
|
||||
No breaking changes - upgrade directly from v0.7.0.
