What i'm really wondering right now is what is with that guy that said we all need to patch our miners a few pages back ?
He was saying something about it fixing reporting to P2Pools ? something to do with pseudo-share settings ?
I don't know if this miner is actually "patched". The original code had a problem with very low diffs. The problem was that it did a fast pre check which only allowed diffs 0f 0.0039... or higher. Thus when a fresh p2pool was set up, the pool did give out lower diff. But the miner only reported back hashed above 0.0039. Thus the p2pools speed calculations was wrong, as well it may happend that valid pool shares was thrown away (ONLY poolshares, NEVER valid block hashes)
This commit beside some other thing has the fix in it:
