[ANNOUNCE] WireGuard Snapshot `0.0.20180708` Available

[Jason A. Donenfeld]

Hey Roman,

Thanks for the update. That's great to hear.

The latest snapshot will still have the same preemption relaxation
with simd_relax(), but gets performance gains by moving to napi, so
it's still faster overall. If you want the simd_relax() to not take a
hit and get maximum throughput, the right way of doing this is
actually to just disable preemption in your kernel with
PREEMPT_NONE=y.
