- ✅ **No EOL components**: Everything actively maintained

## 📊 Version Comparison Impact

### Build Time Impact
| Metric | Old Versions | Alpine 3.22 | Improvement |
|--------|-------------|--------------|-------------|
| **Security patches** | Manual | Automatic | 100% automated |
| **Feature updates** | Complex | Simple | Package manager |
| **Compatibility** | Unknown | Tested | Alpine integration |
| **Maintenance** | High effort | Minimal | Alpine team handled |

### Runtime Improvements
- **Better hardware support**: Latest drivers and firmware
- **Performance**: Years of optimizations
- **Security**: No EOL vulnerabilities
- **Features**: Latest tool capabilities

## 🎯 Implementation Updates

### Updated Dockerfile
```dockerfile
FROM alpine:3.22  # Was: alpine:3.19

# All packages automatically get latest versions:
# - OpenSSL 3.3.x (was: 1.1.1d EOL)
# - Linux 6.12.42 LTS (was: 6.8.8)
# - All tools: current stable versions
```

### Package Selection Strategy
```yaml
Approach: Trust Alpine Curation
- Use Alpine 3.22 stable packages
- No version pinning in package list
- Let Alpine team handle version compatibility
- Pin only the Alpine base version (3.22)
```

### Update Process
```bash
# Automatic latest versions
apk add --no-cache package-name  # Gets latest stable

# No need for version specifications:
# apk add openssl=1.1.1d  # Old, manual approach
# apk add openssl         # New, automatic latest
```

## ✅ Migration Benefits

### Security
- **No EOL software**: Everything actively maintained
- **Patch automation**: Alpine security team handles updates
- **CVE response**: Faster than manual maintenance

### Operational
