Changes:

• New project domain: revealjs.com.
• New presentation control arrows:
  • Redesigned for improved aesthetics and clarity.
  • Arrows bounce to attract attention until the viewer first navigates. The downwards arrow bounces the first time you arrive at a vertical stack too, making vertical slides harder to miss. This can be turned off by setting the controlsTutorial config option to false.
  • Arrows automatically change color to contrast the slide background. Step left/right here to test.
  • Initialize reveal.js with controlsLayout: "edges" to have the controls appear along the edges of the screen instead of the bottom right corner. Try it out.
• New mobile-friendly layout for presentations shared with visible speaker notes.
• The showNotes config option no longer shows the notes UI if there are no notes.
• Improved search plugin: added CTRL+SHIFT+F shortcut, now searches inside of <span>. (#1909 by @linux-man)
• Lazy-loaded videos are now unloaded when they move out of view.
• Set the autoSlide option to false to prevent ALL auto-sliding (including data-autoslide attributes).
• New API method Reveal.isSpeakerNotes() to check if the current instance of reveal.js is running inside of the speaker view.
• New API methods Reveal.loadSlide()/Reveal.unloadSlide() for manually triggering the content on a slide to load or unload.
• Always show video/audio controls on mobile devices.
• Themes now use default quotation marks for <q>.

Bug fixes:

• Fixed an issue that prevented Reveal.configure() from being called directly before or after Reveal.initialize().
• Don't apply text-transform uppercase inside of code tags. (#1978 by @sfairchild)
• Mobile Safari browser chrome no longer covers presentation content in landscape mode.
• Fixed a feature test exception that prevented speaker notes from working in Safari.
