The plan is, as PhoneBoy wrote, to release M1 support on the next release.
But here is a tip.
Just between you and me, and if you promise not to tell anyone else …
From what we have seem so far, M1 probably works with the last E84.30 GA (using Rosetta 2) for most blades beside Threat Emulation, Forensics & Anti Ransomware (untested, non-committed, unsupported, you did not hear it from me).
So you are welcome to try and use it if you want. I know there are several customers who already use it on M1 with no issues.
If you do chose to use it on M1, I will be happy to hear your feedback – good or bad. Just send me a private message.
