New features

• Revealjs 5 release notes

  • Scroll View (Add scroll view hakimel/reveal.js#3482) (Announcement). Docs: https://revealjs.com/scroll-view
  • 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.

• Reveal 4.6

  • Add the enter-fullscreen class to any element in your presentation to turn it into fullscreen trigger (hakimel/reveal.js@2927be3)
    • It is working, and I believe nothing specific to do in Quarto for this.
  • add support for links to the id of an element nested inside slide (add support for links to the id of an element nested inside slide hakimel/reveal.js#3444)
    • Should help solve Cross-reference to figure in revealjs presentation not working #9742 and other related link issue in slides

• Reveal 4.5

  • Custom fragments ([Revealjs] Define new fragment : fade-semi-out-then-in #4794) (Revealjs 4.5)
    • The text of `<li class="fragment">` temporarily loses its CSS style (in revealjs) #9643 (from 4.5)
  • New Dracula theme (Add theme 'dracula' hakimel/reveal.js#3324) in 4.5.0 (Frame around a code chunk - theme problem #4027 (comment))
  • Jump To Slide shortcute
    • revealjs - Add jumpToSlide support for new revealjs #10998

• From 4.4 no yet integrated or to check

  • gradient slide background - in 4.4.0 (RevealJS gradient background #6873)
  • Multiple note support (hakimel/reveal.js@f9ce61e)
  • zoom should not be used anymore and css transforms are prefered (hakimel/reveal.js@e281b32)

Probably fix

• Slide Number Issues with RevealJS's print-pdf and h1 sections #3997
• revealjs export pdf changes code block font #9699 (fixed in 4.6)

Is it worth updating to 4 while 5 just got released?

[cderv]

Probably not... I was not aware of 5 being out. Really recent... Thanks for the heads up !

[cderv]

Though this will depend on Pandoc support to be able to provide some new feature like scroll maybe 🤔
We'll see

I am very interested in the expected timeline for this.

Also, would be interested in a basic guide to dropping in an updated version of revealjs in my quarto stack manually until such a time as an official release!

That's not a thing that will ever work well in Quarto, so please don't expect it.
