Describe your issue

Custom font family config in @theme stops working at 4.0.0-alpha.32. Confirmed working in 4.0.0-alpha.31.

Elements fell back to the default font. The expected behavior is to use the font family defined in @theme.
Successfully reproduced the issue in the above Playground url. To reproduce yourself, use Tailwind 4.0.0-alpha.32 and configure a custom font family.

@F-fengzi Hey! This is actually a change that we've made to the --font-family variable. It's now called --font only: #14885

We somehow forgot about adding this to the changelog though, I will add this right away. Sorry for the troubles.

Oh 😅! That makes more sense, you guys did change a lot in 32.

Thanks! Hopefully this helps future people too.

Getting ready for a beta release very soon 🤞 After that the API will be a lot more stable*

(* although we still might make changes before the official release, no guarantees haha)

Coooool, excited for it :D
