Crawl4AI v0.7.8 Release Demo - Verification Tests
==================================================

This demo ACTUALLY RUNS and VERIFIES the bug fixes in v0.7.8.
Each test executes real code and validates the fix is working.

Bug Fixes Verified:
1. ProxyConfig JSON serialization (#1629)
2. Configurable backoff parameters (#1269)
3. LLM Strategy input_format support (#1178)
4. Raw HTML URL variable (#1116)
5. Relative URLs after redirects (#1268)
6. pypdf migration (#1412)
7. Pydantic v2 ConfigDict (#678)
8. Docker ContentRelevanceFilter (#1642) - requires Docker
9. Docker .cache permissions (#1638) - requires Docker
10. AdaptiveCrawler query expansion (#1621) - requires LLM API key
11. Import statement formatting (#1181)

Usage:
    python docs/releases_review/demo_v0.7.8.py

For Docker tests:
    docker run -d -p 11235:11235 --shm-size=1g unclecode/crawl4ai:0.7.8
