AI Summary
This patch release hardens the parser against crafted PDFs that could cause unbounded CPU or memory usage while improving extraction quality for nested forms.
Key Highlights
- Caps Form XObject expansion, CID ranges, and content-stream decode to prevent DoS
- Tracks text line matrix in Form XObjects to handle spacing operators correctly
- Merges small-caps runs to prevent them from being read as table columns
New Features
- Security hardening against pathological PDFs and DoS attacks
- Improved handling of nested Form XObject text spacing
- Enhanced extraction quality for small-caps and table structures
