on GitHub

Added

• PDF image placeholder toggle: New inject_placeholders option on ImageExtractionConfig (default: true). Set to false to extract images as data without injecting ![image](...) references into the markdown content.

Fixed

• Token reduction not applied (#436): Token reduction config was accepted but never executed during extraction. The pipeline now applies reduce_tokens() when token_reduction.mode is configured.
• Nested HTML table extraction: Nested HTML tables now extract correctly with proper cell data and markdown rendering, using the visitor-based table extraction API from html-to-markdown-rs.
• hOCR plain text output: hOCR conversion now correctly produces plain text when OutputFormat::Plain is requested, instead of silently falling back to Markdown.
• PDF garbled text for positioned/tabular content (#431): PDF text extraction now detects X-position gaps between consecutive characters and inserts spaces when the gap exceeds 0.8 × avg_font_size.
• Chunk page metadata drift with overlap (#439): Chunk byte offsets are now computed via pointer arithmetic from the source text, fixing cumulative drift that caused chunks to report incorrect page numbers when overlap is enabled.
• Node.js metadata casing: Standardized all Metadata and EmailMetadata fields to camelCase in the Node.js/TypeScript bindings. Also corrected pluralization for authors and keywords.
• WASM build failure on Windows CI: CMake try-compile checks on Windows used the host MSVC compiler (cl.exe), which rejected GCC/Clang flags like -Wno-implicit-function-declaration. Added CMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY to WASM cross-compilation builds.
• WASM OCR build panic when git/patch unavailable: The tesseract WASM patch application panicked when both git apply and patch commands failed. Added programmatic C++ source fixups as a fallback, applying all necessary changes via idempotent string replacements.
