Changelog

0.6.0

• Breaking: Removed has_redlines?/1. Callers should use extract/2 and check result.changes == [] instead. The old heuristic pre-check doubled the PDF rendering cost and risked false negatives on non-standard redline colors.
• Bumped pdf_redlines to ~> 0.7.0.
• Added performance section to README (under 700 ms on 35 MB+ scanned documents).

0.5.1

• Bump pdf_redlines dependency to ~> 0.6.3

0.5.0

• pdf_redlines is now a required dependency (precompiled NIF, no toolchain needed).

• Expanded README with badges, full API docs, and usage examples.

0.1.0

• Initial release.
• DOCX track-changes extraction from word/document.xml.
• Optional PDF extraction via the pdf_redlines package.
• Unified Redlines.Change shape and Redlines.format_for_llm/1.
