Yup, there were some premature release announcements, but it seems it's really available now. (Note that OpenBSD releases come out twice a year, pretty much like clockwork, and that version numbers aren't indicative of the magnitude of the underlying changes: 7.0 was just the next release after 6.9).

Headline improvement for this version: it's fully supported on Apple Silicon. Not sure there is a huge market for that, but still pretty cool!
