Release Notes

hakimel/reveal.js

v4.4.0

Compare Source

Changes

• Gradient slide backgrounds, read the docs 🌈 (@​gcmznt in #​2510)
• If multiple separate notes are provided for the same slide they will now all show in the speaker view (@​lechten in #​3010)
• Updated browser targets from > 0.5%, IE 11, not dead to > 2%, not dead
• Stop using zoom for presentation scaling. Zoom produced sharper upsizing than CSS transforms but it's a non-standard CSS property with a few too many quirks. e281b32

tldr — self-destruction and bug fixes 💣

Changes

• It's now possible to destroy/uninitialize a reveal.js presentation. This will remove all event listeners and roll back all changes made to the DOM. It will also unregister all plugins and destroy them if they expose a destroy method. (#​1145 / @​hakimel)

  Reveal.destroy();

• You can now provide an absolute URL to the presentation that should be loaded in the speaker view. This is useful if you have a presentation integrated as part of a web page but still want the speaker view to work.

  Reveal.initialize({ url: 'https://example.com/my-reveal-presentation' })

• Source maps are now included in dist (#​3082 / @​dabrahams)

Fixes

• Fix the speaker view no longer goes out of sync with your presentation after live-reloading (#​2822 / @​hakimel).
• Fix XSS vulnerability in speaker view (#​3137 / @​r0hanSH)
• Fix issues with scaling embedded presentations when entering fullscreen mode in Safari (#​3080 / @​Martinomagnifico)

v4.2.1

Bug fix release 🐛

Fixes

• Fix an issue where some slides disappeared (fully or partially) after slide transitions in Chrome (9e583b8 @​hakimel)
• Fix an issue that caused double-navigations and impacted presentation performance (@​hakimel #​3079)
• Fix --host not working in npm start -- --host=0.0.0.0 (@​cashcat #​3075)
• Fix incorrect sizing of auto-sized text in PDF exports (https://github.com/hakimel/reveal.js/issues/2865#issuecomment-970258829 @​hakimel)
• Fix background video playback issue in some browsers by inferring MIME type from file extension (#​3078 @​vanch3d)

v4.2.0

Compare Source

Changes

• The math plugin now supports three typesetting libraries: KaTeX, MathJax 2 and MathJax 3. We continue to use MathJax 2 as our default so this is fully backwards compatible. Learn how to choose between typesetters and how to configure them in the docs at https://revealjs.com/math#typesetting-libraries (@​burgerga in #​2559).
• New event: beforeslidechange (#​3003). This makes it possible to conditionally prevent navigations:

  // This prevents all slide changes
  Reveal.addEventListener( 'beforeslidechange', e => e.preventDefault() );

• New keyboard shortcut for skipping fragments while navigating: alt + ←/↑/→/↓.
• New API option for skipping fragments in directional navigation Reveal.right({ skipFragments: true }).
• Adds a beforeHighlight callback to the highlight plugin (@​rajgoel in #​3026).

  Reveal.initialize({ 
    highlight: {
      beforeHighlight: (hljs) => {
        // interact with highlight.js, for example to register a new language
      }
    } 
  })

• Code line numbers can now start from an offset (#​3050). For example, this code block would begin its line numbering from 10: <code data-ln-start-from="10">.
• Better error messaging when the .reveal or .slides containers are missing #​2217.

Fixes

• The last slide keyboard shortcut now works for looped presentations (#​3007).
• Markdown code blocks can be turned into fragments (@​nicojs in #​2982).
• Unit tests can now run in Windows (@​Vandivier in #​3027).
• Restored support for base64 background images, broken since 4.1.1 (#​2978).
• Fixes an issue that prevented presentations from looping when navigationMode was set to linear.
• Internal links leading to a slide with video/audio element will now correctly start media playback. This issue only affected mobile browsers.

v4.1.3

Compare Source

v4.1.2

Compare Source

Changes

• Adds support for data-auto-animate-restart and data-auto-animate-id. These properties give you finer control over which slides that should auto-animate between each other (@​coffeenotfound in #​2896).
• Theme properties are now available as CSS variables, making them easy to override. Full list of variables (#​2740 + #​2968).
  Here's an example you can drop into your presentation's HTML:

<style type="text/css">
:root {
  --r-background-color: indigo;
  --r-main-color: #f5f5f5;
  --r-main-font: monospace;
}
</style>

Fixes

• Markdown enabled speaker notes (<aside class="notes" data-markdown>) are no longer visible on-slide.

v4.1.1

Compare Source

Mostly bug fixes and enhancements 🐛

Changes

• Adds support for Node.js 16.
• data-background-image now accepts multiple images (#​2940).

• More accurate calculation of which slide to jump to when clicking on the progress bar (#​2836).
• Optimize DOM interactions and reduce forced layouts when exporting to PDF (#​2843).

• Markdown is now split into individual slides by the default separator (---) as advertised.
• The r-fit-text layout helper now sizes text correctly in PDF exports.
• Fixes an issue where some slide-specific transitions were incorrectly overridden by the global transition setting.
• The has-dark-background helper class now works when using named colors for data-background-color (#​2933).
