[SU9] Cudos for releasing the SDK and SDK notes / documentation with it

Dear Asobo, I just wanted to write a simple note to say thank you for
releasing the SDK 18 with SU9 and having the documentation (even online) for
it ready at the same time. This give us the chance not only to test SU9 but
also the SDK that goes alongside with it. Once again many thanks for this
effort. Best Regards, Raul
