I've been running P2Pool on Linux for about a year and decided to look for updates... I'm hoping that the 'bug' causing all my shares to be lost when I restart the pool has been fixed.

I'm confused; there are a multitude of 'p2pool' projects on GitHub

What is considered to be the latest 'official' repository for the p2pool code

Or.. can anyone spell out what the different 'good' repositories are, and what the differences between them are ?
