All versions since 1.3.1

1.3.1

Tooltips on mobile rendered outside the viewport near screen edges. Horizontal position now clamps with 8px padding; arrow shifts to track the trigger.
Tooltips stayed visible while scrolling on touch devices. Dismisses when the trigger moves 50px from its open position or leaves the viewport.
Tapping a tooltip after scroll-dismiss had no effect. Trigger now blurs on scroll-dismiss so the next tap re-focuses.
Tooltips near the top of the page overlapped Starlight’s fixed header and “On this page” dropdown. Flips to bottom when space above is insufficient (100px header safe zone).

H1/H2 now use Noto Serif (--nu-font-display), H3–H6 use Poppins (--nu-font-heading). Sizes, weights, and colors match the Department 4.0 stylesheet.
Poppins 400 loaded the Light file instead of Regular. Poppins 500 (Medium) added from v4 CDN.
Table headers now use --nu-purple-100 with white text.
Table striping moved to odd rows (#f9f6ff); dark mode uses rgb(78 42 132 / 10%).
--nu-purple-surface corrected to #f9f6ff, --nu-purple-surface-subtle to #f3f0f7.
Blockquote background uses #f9f6ff instead of translucent purple.
Horizontal rules use 3px --nu-purple-10 instead of 1px gray.
List markers use --nu-purple-100 instead of --nu-purple-40.

Open Graph image generation: builds a branded 1200x630 PNG per docs page. Favicon logo, page title, and description on Northwestern purple with a light purple accent border. Slack, Teams, and social media link previews use these images.
- Enabled by default. Set site in your Astro config. pnpm users: run pnpm add canvaskit-wasm to enable (build skips OG gracefully without it).
- Disable with ogImage: false.
- Adds og:image, og:image:type, og:image:width, og:image:height, og:image:alt, og:logo, twitter:image, and twitter:image:alt meta tags to every page. Overrides twitter:card to summary_large_image.
- New dependency: astro-og-canvas.

defineNorthwesternConfig config helper. Single function that returns a complete Astro config with integration ordering (mermaid → starlight), plugin registration, and Expressive Code. Replaces the manual defineConfig + starlight() + northwesternMermaid() wiring. New ./config package export.
Automatic Expressive Code line numbers. defineNorthwesternConfig injects pluginLineNumbers() and GitHub syntax themes (github-dark / github-light). No ec.config.mjs file needed. A Vite plugin separates serializable config from plugin instances so the <Code> Astro component continues to work.
Type declarations (.d.ts) shipped for all public exports.
OG images for changelog version pages with multi-line titles (e.g., “Changelog / 1.4.0”).
JSON-LD structured data on each page.
Unit test suite (Vitest) covering config.ts, expressive-code.ts, mermaid.ts, and rehype-table-scroll.ts. E2E tests moved to tests/e2e/. CI runs unit tests in a dedicated job.

Replaced astro-og-canvas + canvaskit-wasm with satori + @resvg/resvg-wasm. pnpm users no longer need canvaskit-wasm as a direct dependency.
OG image generation logs a warning and disables when Starlight title is empty or site is not set, instead of crashing or producing broken URLs.
OG font buffer uses correct Uint8Array offset slicing instead of casting the full backing ArrayBuffer.
Larger OG text: title 48→56px, description 28→32px, logo 60→80px. Separate vertical (60px) and horizontal (220px) padding to avoid clipping.
Runtime config validation now catches invalid theme, Mermaid, and config-helper options with friendly errors at the public API boundary instead of failing later with cryptic behavior.
Rehype table scroll skips tables already inside .nu-table-scroll, preventing double-wrapping on incremental rebuilds.
Aside borders use solid brand colors (#5091cd, #008656, #ffc520, #ef553f) and a 3px left accent stripe instead of a translucent 1px box border. Dark mode borders match the text accent for each variant.

h1 keeps Noto Serif; h2–h6 switched to Poppins.
Package exports map includes types fields pointing to dist/*.d.ts for all entry points.

Legacy .html redirects. Sites migrated from VuePress had every page served at <slug>.html; external bookmarks and inbound links still point there. A new legacyHtmlRedirects option on defineNorthwesternConfig (default true) scans src/content/docs and emits a redirect from <slug>.html to the canonical <slug>/ URL for every page, with the URL hash preserved on forward so deep links like #schedule-management still land on the right anchor.
