It's possible to fine tune this view through multiple new config options. Full documentation available at https://revealjs.com/scroll-view.

Breaking change

The scroll view is automatically enabled for viewports below 435px wide. This is done because I believe the scroll view to be a superior way to browse any deck on a mobile device. If you want to revert this behavior and always paginate between slides, see scrollActivationWidth:

Reveal.initialize({ scrollActivationWidth: null })

Changes

• The PDF print view can now be activated via config Reveal.initialize({ view: 'print' }) (@hakimel in #3482)
• The new URL query for activating the print view is ?view=print. It used to be ?print-pdf, which is still supported for backwards compatibility. (@hakimel in #3482)

Fixes

• Notes from data-notes were not working on the slide-level (@skyboyer in https://github.com/hakimel/reveal.js/pull/3477)
• Add 'wheel' event listener, remove deprecated mousewheel & 'DOMMouseScroll` (@quochuy in https://github.com/hakimel/reveal.js/pull/3489)
