If you keep using previous versions, you will keep mining as usual, but become almost a solo miner, as incompatible clients will mine on their own. After the fork, you can check on OLD-MINI.P2Pool.Observer . After upgrading to a supported P2Pool version and mining a share, this message will be dismissed.
