OCI Runtime Specification 1.3 adds FreeBSD

Version
1.3 of the Open Container Initiative (OCI) Runtime
Specification has been released. The specification covers the
configuration, execution environment, and lifecycle of containers. The
most notable change in 1.3 is the addition of FreeBSD to the
specification, which the FreeBSD Foundation calls
'a watershed moment for FreeBSD':

The addition of cloud-native container support complements FreeBSD's
already robust virtualization capabilities, particularly the powerful
FreeBSD jails technology that has been a cornerstone of the operating
system for over two decades. In fact, OCI containers on FreeBSD are
implemented using jails as the underlying isolation mechanism,
bringing together the security and resource management benefits of
jails with the portability and ecosystem advantages of OCI-compliant
containers.
