Is it only M1 macs, or are other M-series supported too (or maybe they were previously)?

Hard to tell if this is a major breakthrough or just an incremental improvement.

AFAIK only M1 -- but yes, it's a major achievement: AFAIK this is the first bare-metal Haiku on Arm.

I'd like to know this too, especially the ipad.
