server.
The
announcement
reads in part:

Changes in this release:
========================

Includes the following security fixes:
  - OpenBSD 7.2 errata 20 "smtpd(8) could abort due to a
    connection from a local, scoped ipv6 address"
  - OpenBSD 7.2 errata 22 "Out of bounds accesses in libc resolver"

Configuration changes:
  - The certificate to use is now selected by looking at the names
    found in the certificates themselves rather than the `pki` name.
    The set of certificates for a TLS listener must be defined
    explicitly by using the `pki` listener option multiple times.
