Even the daily build for 24.10 doesn’t show any arm releases; just amd. The manual link to daily live (https://cdimage.ubuntu.com/daily-live/manual/) has the arm releases, but they’re dated 04/17/24. The iso found at the link to arm server (https://ubuntu.com/download/server/arm) has the same hash as the one dated 04/17/24.

It’s curious, because the daily builds for jammy (22.04), including arm, seem to be up-to-date.
