 ## 0.21.9
 
 ### Enhancements
-- **Optimize PDF render mode patching performance**: Optimized `_patch_current_chars_with_render_mode` in `CustomPDFPageInterpreter` to avoid O(N²) re-scanning by tracking the last-patched index, so each `do_TJ`/`do_Tj` call only processes newly-added characters.
+- **Check Complex Documents**: Check for a high ratio of vector graphics to avoid pdfminer
