If you don’t want to wait for the official package to be released to get new features and security patches, you can manually install the Tailscale package from the source.
I saw there were some Tailscale client security updates in recent weeks.
So I updated CE 2.7.2 to tailscale 1.68.1
pkg add -f https://pkg.freebsd.org/FreeBSD:14:amd64/latest/All/tailscale-1.68.1.pkg
tailscale version
1.68.1
go version: go1.22.4
Seems to be working.
