The preview‑deployment docs don’t appear to include the new "today" key in the theme configuration. Is there anything missing that needs updating?

[rluders]

@jonasho Nope, forgot about it, I'm seeing it there. Mobile app for github is terrible. Where don't you see the today in the docs?

@rluders—never mind, I found it. The search on the preview stage redirected me to the official site; I didn’t notice that earlier. Looks good now.
