If sshd is running, and a system is upgraded from <net-misc/openssh-8.2_p1 to >=net-misc/openssh-8.2_p1, any new ssh connection will fail until sshd is restarted.

Before restarting sshd, it is *strongly* recommended that you test your configuration with the following command (as root):

  sshd -t

If your system is booted with openrc, use this command (as root) to restart sshd:

  rc-service sshd --nodeps restart

If your system is booted with systemd, use this command (as root) to restart sshd:

  systemctl restart sshd

WARNING: On systemd booted machines with PAM disabled, this command

       will terminate all currently open ssh connections. It is 
       *strongly* recommended that you validate your configuration
       before restarting sshd.

If you are using systemd socket activation for sshd, then no action is required.
