As a complete noob to p2pool, thanks to veqtrus for creating a Segwit version that doesn't require me to move away from Core bitcoind.  17.1 seems to be working fine now with no scary error messages from p2pool or bitcoind.  I wanted to signal my support for segwit, but not segwit2x.  Thank you for giving me a way to do that!  It was a bit of a convoluted path to find it tho.  I am sure there are a lot of miners that just upgraded everything per the error message and end up supporting segwit2x without knowing it... clearly.  I wish there was a clear path of instructions out there for those that support segwit, then another for those that support segwit2x.  In any case, thank you veqtrus for supporting what i consider at this point to be "real" bitcoin.
