Changelog

What changed, and when.

Every released version of the a11y extension, and what each one changed.

0

docs: Add a documentation website under docs/, built on the atelier project type and published to https://m.canouil.dev/quarto-revealjs-a11y/, including a deck with every control enabled.
docs: Trim README.md to a landing page pointing at the website.
docs: Add the Pages workflow, which renders docs/ on pull requests and deploys it from the release tag.
docs: Add the Quarto Extensions Updates workflow, scanning docs for the website’s own dependencies.

fix: increase letter-spacing, word-spacing, and line-height selectable maximum values.

feat: announce language changes to screen readers when navigating between slides with different lang attributes (announce-language-changes option, enabled by default).
feat: allow zooming by overriding the Reveal.js viewport meta that set user-scalable=no (viewport-zoom option, enabled by default; WCAG 1.4.4).
feat: add transcript view that linearises slide content into a screen-reader-friendly document (transcript option). Authors can provide custom transcript text via ::: {.transcript} blocks; otherwise the slide’s visible content is used. Optionally show transcript below each slide in print-pdf mode with transcript: {print: true}.
feat: add pointer/focus indicator for low-vision users (pointer-indicator option). A configurable spotlight follows the cursor or keyboard focus, with size and colour adjustable from the accessibility menu.
feat: improve print-pdf output by resetting user preferences, hiding interactive UI, preserving backgrounds, and supporting per-slide fragment separation via {data-pdf-separate="true"} and {data-pdf-no-separate="true"} attributes.

fix: label the bundled reveal.js-menu toggle button so screen readers announce it (slide-menu-a11y).
fix: queue and coalesce status announcements so rapid slide or fragment changes are no longer lost to the requestAnimationFrame race; consecutive duplicates are dropped and queued messages are flushed at a polite cadence.
fix: validate pointer-indicator.size (numeric, clamped to [16, 800] px) and pointer-indicator.colour (parsed as a CSS colour) at configuration time; invalid values fall back to defaults and are reported via console.warn.
fix: render the local font picker in chunks via requestAnimationFrame so very large font collections no longer block the main thread; search input is debounced.
fix: replace the generic “Could not access local fonts” message with permission-aware help text covering denial, insecure contexts, and unsupported browsers.
fix: cancel the in-flight announcement timer and clear the queue on plugin teardown.
fix: treat alt="" as a valid decorative-image declaration; the “missing alt text” warning is now only shown when the alt attribute is absent entirely.

fix: remove version-specific reference (added from CI/CD) from the GitHub repository link to ensure it always points to the latest version.

feat: Initial release with skip navigation, focus indicators, reduced motion, high contrast mode, font size controls, font selection, slide landmarks, alt text warnings, and screen reader announcements.
