• Updated browser targets from > 0.5%, IE 11, not dead to > 2%, not dead

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

Compare Source

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 🐛

• The has-dark-background helper class now works when using named colors for data-background-color (#​2933).

Breaking Changes 🚨

This release includes a small number of breaking changes. Please read the Upgrade Instructions if you want to migrate an existing presentation.

Highlights

• New website, docs and logo! https://revealjs.com/ 🚀
• Auto-Animate lets you create complex animations by automatically transitioning between matched elements across slides. Duration, delay and easing can be set on a per-slide or per-element basis.
• We now support multiple presentations on the same page.
  • This also introduces a new embedded config option, which allows presentations to reside within a portion of a page. Previously reveal.js always covered 100% of the page width and height.
  • The new keyboardCondition: 'focused' config option lets presentations capture keyboard events only when they're focused by the viewer.
• The reveal.js core and built-in plugins have been rewritten as ES modules. This makes the project easier to maintain and makes reveal.js itself easier to include in a bundle. Two bundles are provided:
  • dist/reveal.js uses UMD and has broad cross browser support (ES5).
  • dist/reveal.esm.js is an ES module. More info
• Code highlights are now automatically scrolled into view and it looks soooo good. You've got to try it out.

Changes

• The Reveal.initialize method now returns a promise that resolves once reveal.js is ready and all plugins have finished initializing.
• Switches build systems from to gulp, using rollup for bundling.
• Moves all compiled CSS (reveal.css, reset.css and themes) from css/ to dist/. See Upgrade Instructions.
• Moves all print CSS into reveal.js. The old script-based print styles can be removed. by @​quilicicf
• Adds a new slidetransitionend event.
• Adds a new r-stack layout helper for placing elements on top of each other.
• Adds support for data-visibility="uncounted" to exclude slides from the progress bar and slide number count. #​2543 by @​lassepe
• Adds Reveal.getComputedSlideSize API method.
• Renames the Reveal.addEventListener and Reveal.removeEventListener API methods to Reveal.on and Reveal.off. Old names are aliased for backwards compatibility.
• Removes the default border style from <img>s. Can be added with the r-frame class.
• Removes bower.json.

Plugins

• New syntax for registering plugins.
• All built-in plugins—such as markdown and highlight—are now available as ES modules. More info
• Notes: No longer depends on resolving an external notes.html file to work. Everything is baked into the plugin JS.
• Highlight: Upgraded to highlight.js 10.0.1.
• Highlight: Moved highlight themes from lib/css/monokai.css to plugin/highlight/monokai.css.
• Highlight: 'highlight.js' library is now installed from npm instead of being saved in the repo.
• Markdown: Support for line numbers and highlights in syntax highlighted code.
• Markdown: Support for boolean data- attributes. by @​Bagira80
• Markdown: 'marked' library is now installed from npm instead of being saved in the repo.
• Multiplex: Moved out to https://github.com/reveal/multiplex
• Notes Server: Moved out to https://github.com/reveal/notes-server

Bug fixes

• Fixes a bug that prevented links from working in exported PDFs. #​2628 by @​telliott22
• Fixes a bug where navigationMode: 'linear' incorrectly hid valid vertical directions. #​2582 by @​earboxer
• Fixes an issue that caused reveal.js to incorrectly block keyboard events when an element with contentedtable=false was focused. #​2650
