Changes:

• Turn on the showNotes option to show your speaker notes along the bottom of the presentation. Also works with PDF exports!
• If slideNumber is turned on slide numbers will now be included in PDF exports.
• Changed the format and style of slide numbers.
• Added a bower.json manifest #1067
• Use data-prevent-swipe to flag that swiping across an element shouldn't trigger slide navigation (more info, #951 by @calyhre)
• Accessibility: control arrows were changed from <div> to <button>.
• Updated all dependencies, see ef1402e64567a41be8ac56ad129fdeb54a275218
• The Multiplexing and Speaker Notes plugins have been upgraded from socket.io 0.9.x to 1.3.7.
• The server side speaker notes plugin now syncs changes from within the notes window to the main presentation window.
• We no longer use zoom to scale down presentations since that was causing slight shifts in text layout. Instead we're relying on transforms which always interpolate smoothly although things don't look as crisp.
• The Leap Motion plugin was moved out of reveal.js core: https://github.com/gneatgeek/reveal.js-leap-motion
• The remotes.io plugin was removed.
• Updated highlight.js from 8.2 to 8.9.1
