Fairly recent (dated October 12). I can't vouch for the accuracy but it looks pretty good. This may come in handy for those who want to participate in the Hubitat Matter Beta (C-8 Hubs only).
Does Hubitat support only Matter over WiFi at this point?
Join the Beta
Yes AFIK there are no plans for thread support on the C8 because it would require time slicing the radio.
However from what I understand if you were to join a thread matter device to a Thread Border Router, you could then join it to other controllers on the IP network via the border router.
