you have any links for the new software to mine it?
Latest xmr-stak v2.5 and 2.4.7 in SMOS supports v8
The cool thing is that you select the algo to be just "monero" and it will mine v7 and switches to v8 on D-day automatically
I have this setup in nanopool currently with some test rigs (NVIDIA and AMD) and its happily mining v7.
Meantime, both GPU farms are fully up mining XVH until 2359 17th October.
