Where did deforum go?

Pardon the naive question.
I haven't been paying attention to AI image generation for a few months, so I've probably missed some stuff.

I'm running forge on ubuntu with a 3090.

Today I updated and ran forge.
I noticed that the deforum tab was absent.

I went to the extensions tab, found a listing for deforum and loaded it.

After restarting the UI, deforum was still absent.

How do I get deforum working?

Please don't tell me that I have to use comfyui to run deforum. Comfyui makes me nauseous.
