v2.0.0

Added

• Support for files created by the OneNote desktop application (2016, 2019, LTSC, …), in addition to files downloaded from OneDrive. The file format is detected automatically.
• Split the crate into a reusable library and an optional CLI binary (gated behind the bin feature), and add a wasm32-unknown-unknown build of the library.
• Support .onepkg packages in addition to .one sections and .onetoc2 notebooks (gated behind the onepkg feature).
• LaTeX math rendering alongside MathML, selectable with --math-target {mathml,latex}; the matching MathJax build is loaded automatically.
• Optional per-section "⚠ Conversion Warnings" page via --warnings, listing non-fatal parser issues.
• Render math-only paragraphs as display-mode equations.
• Render arbitrarily nested section groups in the notebook table of contents.
• Optional emoji rendering for note-tag icons.
• Emit <strong>/<em> for bold and italic text runs.
• Emit X-Original-Page-Id, X-Created-Time, and X-Updated-Time meta tags per page.
• Support nested ink containers and improve handwriting import via batched ink rendering.
• Emit OneNote's handwriting OCR as an SVG <title> on each rendered ink block, making the recognized text available to screen readers (#9).
• Add a --version flag to the CLI.

Changed

• Update onenote_parser to 2.0.0 (see its release notes).
• Stream image and embedded-file payloads to disk instead of buffering them in memory.
• Sanitize output filenames for the target filesystem, so conversions are reproducible regardless of the host platform.
• Don't force the native-fs feature on library consumers.
• Fall back to sans-serif for Calibri and Calibri Light when those fonts are unavailable.

Fixed

• Warn and skip nested section groups instead of aborting the conversion.
• Render tagged-list items as <li> and prevent list-tag styling from bleeding into following items.
• Stop dropping content when text runs have no formatting or when text-run boundaries exceed the available styles.
• Stop folding a single text run's style into the paragraph wrapper.
• Handle hyperlink URL markers split across multiple hidden runs.
• Position inline ink against the bounding-box size rather than the content size.
• Import PDF printouts as PNG when the embedded bytes are actually PNG.
• Use correct bound placement in MathML integrals.

Security

• HTML-escape user-controllable strings — page titles, text runs, hyperlink URLs, and style/href/src attribute values — to prevent HTML/script injection from untrusted OneNote files.
• Prevent path traversal when writing images whose OneNote file extension contains path separators (GHSA-86gx-fw5h-h2gp).
