If you would like to test it out for your own site, you can provide your Netlify slug here and use the Beta image.
@onedrawingperday this gets interesting for the Hugo theme site when the new build image is out of the beta phase
I suppose that now the Hugo website theme can now use SCSS and PostCSS if needed.
But for themes that use the Hugo Extended pipeline, they’ll still need to commit their resources so that they’re compatible with the Basic version of Hugo.
BTW Happy Christmas and all that jazz!
