Here are the commands I used:

gitup release
cd /usr/src/secure/usr.sbin/sshd/
make all
make install
cd /usr/src/secure/lib/libssh/
make all
make install

Before running these commands, the date was "OpenSSH_9.6 FreeBSD-20240104," and after executing them, the date updated to "OpenSSH_9.6 FreeBSD-20240701."

To be certain, I plan to do a full rebuild today.
