[dependabot[bot]]

Bumps reveal.js from 3.8.0 to 4.3.0.

Release notes

Sourced from reveal.js's releases.

4.3.0

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)

4.2.1

Bug fix release 🐛

Fixes

• Fix an issue where some slides disappeared (fully or partially) after slide transitions in Chrome (9e583b8df4edecb94cb89f012ae5c80014a859ee @​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 (hakimel/reveal.js#2865 @​hakimel)
• Fix background video playback issue in some browsers by inferring MIME type from file extension (#3078 @​vanch3d)

4.2.0

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">.
