You're not, it wasn't released yet. Update to 111 and you'll see it (i'm on Max20, i do)

Heck, mine just automatically set it to 4.7 and xhigh effort (also a new feature?)

Thanks, I was already on the latest claude code, I just restarted it and now it's showing 4.7 and xhigh.

xhigh was mentioned in the release post, it's the new default and between high and max.
