Are packages for pkg.freebsd.org built on -STABLE or latest -RELEASE?

After 11.2 is released, if package for nvidia-driver
is installed or upgraded on a machine with 11.1-RELEASE,
will it crash the kernel?

If the port nvidia-driver-304 is updated before 11.2 is released,
will `pkg upgrade` crash the kernel?
