Breaking Changes

• Heading IDs now follow GitHub-compatible VS Code slug generation. Existing internal anchors in your documents may change.
• Highlight.js upgraded from v9 to v11. Some highlight style names have been renamed or removed. Legacy names are mapped to current names when possible, and tomorrow.css is used as a fallback when no mapping is available.
• Front matter parsing is now handled by a custom implementation. YAML sequences and non-plain objects in front matter are now rejected.
• Chromium download and cache management moved to a built-in chromium-resolver. The previous temporary directory fallback has been removed; the managed Chromium is stored under the VS Code global storage directory.

Changes

• Migrate source code to TypeScript and bundle the extension with esbuild
• Bundle puppeteer-core and manage Chromium via the built-in chromium-resolver, preferring an installed Chrome/Edge and falling back to an automatic download
• Replace markdown-it-include, markdown-it-named-headers, and markdown-it-checkbox with in-repo custom implementations
• Remove cheerio, mustache, and gray-matter dependencies in favor of internal implementations
• Add unit and integration test suites using vscode-test-cli, including sample generation and HTML snapshot comparison
• Simplify VS Code variant detection and remove the obsolete temp-cache fallback

Fixes

• Fix global storage path resolution for the Chromium cache
• Gracefully handle include errors in the custom markdown-it-include plugin
• Image src transformation now handles quoted attributes, flexible spacing, and raw-text contexts correctly
• Front matter parsing now handles BOM-prefixed files and rejects invalid structures
