v1.1.0 — LaTeX math (KaTeX)

6 hours ago

v1.1.0

Released: 2026-09-18

Changes since v1.0.1 (5105c20..HEAD).

Features

  • LaTeX math rendering with KaTeX (#164, design by @rafaself): inline $…$ and block $$…$$ math now render in the markdown preview. Fully self-hosted — KaTeX 0.16.47 and its fonts are vendored, so no CDN or network request is needed to render equations.
    • Security-preserving pipeline: the markdown extensions emit text-only placeholders (raw TeX as escaped text, no style) that pass DOMPurify untouched; KaTeX then renders them after sanitization with trust: false, so its style-heavy output never has to go through the sanitizer and the existing HTML-sanitization boundary is unchanged.
    • Conservative tokenizers keep prose literal: currency ($10, $5 and $10), inline code, fenced code, and escaped \$ are not treated as math. Block equations participate in editor↔preview scroll-sync, and re-rendering is idempotent.

Security

  • ruby_llm 1.16.0 → 2.0.0 — clears CVE-2026-67991 (High-severity polynomial-time ReDoS). The AI image-generation path was adapted to the 2.0 API (attachments via ask(prompt, with:), responses as Message#attachments/#content); grammar-check behavior is unchanged.

Test Coverage

  • 864 Ruby tests, 1,646 JavaScript tests (2,510 total).
