OpenBSD 6.1 has been released. It's the first version not to have shiny-circles available. The short version [undeadly.org] points out the addition of syspatch (which should make upgrading easier one of these years). The long version [openbsd.org] notes, among other things, support for ARM64, which includes, if you're a thrill-seeker, the ability to run OBSD on a Raspberry Pi 3 [undeadly.org] which seems relatively cool. Or at least cheap.
And of course, there's a new song [openbsd.org].
