## Version History Summary

| Version | Date | Status | Key Features |
|---------|------|--------|--------------|
| **1.0.1** | 2025-09-27 | ✅ **Current** | Complete API compliance, multi-region support, professional packaging |
| 1.0.0 | 2025-09-27 | ⚠️ Deprecated | Initial release with API inconsistencies |

## Migration Guide

### From 1.0.0 to 1.0.1

**No breaking changes** - all existing code continues to work. However, you now get:

```python
# Before (1.0.0) - still works but limited
from aigc_compliance import ComplianceClient
client = ComplianceClient("your_api_key")
result = client.comply("image.jpg")

# After (1.0.1) - enhanced with full API support
from aigc_compliance import ComplianceClient
client = ComplianceClient("your_api_key")

# Now with full parameter support
result = client.comply(
    file_path="image.jpg",
    region="EU",  # Proper case, full GDPR compliance
    watermark_position="bottom-right",
    logo_file="logo.png",
    include_base64=True,
    save_to_disk=False
)

# New methods available
health = client.health()
file_data = client.download_file("file_id")
```

### Upgrade Instructions

```bash
# Upgrade to latest version
pip install --upgrade aigc-compliance

# Verify version
python -c "import aigc_compliance; print(aigc_compliance.__version__)"
```
