MarkItDown 2Ways v1.0.0

MarkItDown 2Ways v1.0.0 freezes the H1-H33 preservation-first bidirectional contract.

Highlights

  • 17 native format families with explicit bounded mutation authority.
  • 12 derived semantic surfaces with explicit native_writeback=false.
  • Evidence-driven DocumentIR, typed edits and capability reporting.
  • Source/native ownership revalidation and fail-closed mutation.
  • Canonical IR serialization with a machine-readable v1 compatibility corpus.
  • H31 adversarial capability hardening.
  • H32 golden compatibility court.
  • H33 deterministic engineering budgets.
  • Python 3.10-3.13 package/OCR CI coverage.

Native families

Text/Markdown, CSV, JSON, XML, HTML, IPYNB, EPUB, ZIP, PDF, PNG, JPEG, MP3, MSG, XLS, XLSX, PPTX and DOCX.

Derived surfaces

Wikipedia, Bing SERP, remote RSS/Atom, YouTube, Azure Document Intelligence, Azure Content Understanding, AudioConverter, ImageConverter, Outlook MSG converter, PdfConverter, XlsConverter and XlsxConverter.

Compatibility

The product contract is docs/twoways-v1-contract.json. The serialized IR schema remains MarkItDown2WaysDocument@0.1.0; product version 1.0.0 and IR schema version are intentionally separate compatibility axes.

Distribution

This release publishes GitHub wheel/sdist artifacts for this fork. It does not automatically publish or overwrite the upstream markitdown project on PyPI.

Upstream

MarkItDown 2Ways is derived from Microsoft MarkItDown and retains upstream license and attribution notices.
