It's due to this change, sshd now invokes an sshd-session handler instead, for which the master process MUST be restarted: https://www.openssh.com/releasenotes.html#9.8p1 > * sshd(8): the server has been split into a listener binary, sshd(8), > and a per-session binary "sshd-session".

(it's probably advised to restart sshd immediatly after every upgrade, but the package should point this out as Arch does not automate this.) Geert
