WireGuard 1.0.20200401
You use everything here at your own risk. I am not responsible if this breaks your NAS. Realistically it should not result in data loss, but it could render your NAS unaccessible if something goes wrong.
If you are not comfortable with removing your drives from the NAS and manually recover the data, this might not be for you.
This is the first stable release of WireGuard.
