Upgrading?
AI Summary
This release hardens the parser against pathological PDFs that could cause unbounded CPU or memory usage. It adds resource bounds to various PDF operations and improves extraction quality for complex text layouts.
Key Highlights
- Caps Form XObject expansion, CID ranges, and content-stream decode to prevent DoS
- Tracks text line matrix in Form XObjects to handle nested spacing
- Merges small-caps runs to prevent table column misinterpretation
New Features
- Resource bounds enforcement for Form XObjects and content streams
- Enhanced Form XObject text line tracking
- Improved small-caps run merging
