Odd, my node still sayin "5.0", git pulled today.
Anyway, complied last p2pool commit on win32 including LTC this time (finally get mingw working)
http://sdrv.ms/Swy8w9If anyone intrested

Will compile win64 version later today.
I pulled the latest via link and got forrestv-p2pool-4.0-0-g2adf77e.

What link?
git clone https://github.com/forrestv/p2pool.git
Then every week or so
cd ~/p2pool
git pull
And your node is always up to date.
did one more git pull 2 minutes ago, but it's saying "Already up-to-date.". my node still says Version: 4.0-2-g11b0508.
however, i can see v5 increasing in the stats.
btw, my bitcoind is showing version 70003, protocolversion 60002 and walletversion 60000.
