This is a version which should be still in development. Unfortunately, I don't have the time at the moment to continue to work on it. It still has a few flaws, but it is usable if you don't need 100% stability.
This one is the stable series. If you need a module which is as reliable as possible, but don't need the advanced features of v1.4, this is the right version for you.
stats.mod is available on Github.
