Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Changed

  • Migrate all hardcoded neutral-* and sky-* color classes to DaisyUI semantic tokens (base-content, primary, secondary-content, base-100/200/300) for theme-aware styling with proper dark mode support
  • Add styles.css stylesheet and scripts/tailwind.sh build script for Tailwind CSS compilation pipeline
  • Configure hatch build to include styles.css and documentation files in sdist distribution

[1.5.1] - 2026-05-11

Fixed

  • MathJax config escaping: reverted quadruple backslash (\\\\() so JS receives correct \( delimiter
  • Split math expression merge regex: replaced inline replacement string with callback function that checks group3.strip() to avoid creating trailing space before closing $, which broke pymdownx.arithmatex delimiter detection
  • _replace_common_latex_commands_in_text: skip <span class="arithmatex"> nodes so fallback LaTeX→Unicode conversion doesn't strip \( and \) delimiters needed by MathJax

Changed

  • Image caption detection: <em> wrapping a link is now treated as italic text, not an image caption (consistent with _is_image_caption_paragraph)

[1.4.2] - 2026-04-19

Fixed

  • Reduced excessive spacing between images and captions. Added dedicated handling for paragraphs that contain image + caption content in a single block, removed injected <br> spacing in that case, and applied tighter caption typography/spacing classes.

[1.4.1] - 2026-04-19

Fixed

  • _ensure_list_spacing was inserting a blank line before every list item (including items 2, 3, 4…), causing each * item to become a separate <ul> block. It now only inserts a blank line before the first item of a list block (i.e. when the preceding line is not itself a list marker).

[1.4.0] - 2026-04-19

Added

  • Support for 5 new Markdown extensions: abbr (abbreviations with <abbr> tooltip), def_list (definition lists <dl>/<dt>/<dd>), footnotes ([^1] syntax), admonition (!!! note/warning/danger/... callout boxes), toc (auto-generates id attributes on headings for anchor links)
  • Tailwind classes for all new elements: <abbr>, <dl>/<dt>/<dd>, admonition boxes (color-coded by type), footnote section
  • Admonition color scheme: note/info → blue, tip/hint/success → green, warning/caution/attention → amber, danger/error → red, important → purple

Fixed

  • List items (* item, - item, 1. item) and blockquotes immediately following a paragraph (no blank line) were not rendered as HTML lists due to the nl2br extension consuming the newline. A new _ensure_list_spacing preprocessor inserts the required blank line automatically.

[1.3.0] - 2026-04-19

Added

  • font_size parameter on Converter ('sm', 'base', 'lg'; default 'base') to control the typographic scale of all rendered elements
  • --font-size CLI flag (sm | base | lg) passed through to Converter

[1.2.0] - 2026-04-17

Fixed

  • Badge paragraphs now render inline with flex flex-wrap gap-2 items-center justify-center instead of stacked with full line-height spacing
  • Deprecated align="center/left/right" HTML attributes are now translated to Tailwind text-center/left/right classes and removed from output

[1.1.0] - 2026-04-17

Fixed

  • md_in_html extension was a no-op; added _inject_markdown_attr preprocessor to inject markdown="1" into block-level HTML tags so inner markdown (bold, links, badges) renders correctly
  • Double-escaping of Django template delimiters in <pre><code> blocks; <code> inside <pre> is now skipped
  • XSS: audio_id now sanitized with re.sub(r'[^a-z0-9_]', '_', ...) to strip all non-safe characters from inline JS
  • XSS: audio_url validated to only accept http://, https://, or /-prefixed paths; javascript: and other schemes are rejected
  • URL allowlist mismatch between _is_audio_table and convert_tables; both now require the same prefixes, eliminating silent row loss
  • Badge images (inside <a>) no longer inherit the full-width block image classes; they receive inline h-5 align-middle instead
  • Badge links (sole child is <img>) no longer receive text/underline Tailwind classes
  • Removed dead media_suffixes variable from _is_audio_table

[1.0.0] - 2026-04-15

Added

  • Initial release of md2html-tailwind4
  • Converter class with convert_md_to_html() method
  • Tailwind CSS 4 class annotations for all standard HTML elements (h1–h6, p, ul, ol, li, blockquote, img, pre, code, strong, em, a, hr)
  • Responsive table styling with overflow scrolling
  • Audio table support: 3-column tables with media URLs are converted to interactive audio player widgets
  • Django template delimiter escaping ({{ }}, {% %}, {# #}) inside code blocks
  • External links automatically get target="_blank" and rel="noopener noreferrer"
  • Dark mode support via Tailwind dark: variants
  • CLI entry point: md2html input.md output.html
  • src/ layout for clean PyPI packaging with hatchling build backend
