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.
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">.
