[Igal Koshevoy]

The stable releases of the Calagator platform are intended for those that want to run their own Calagator instances, but don't want to upgrade often, and like to only run code we've battle-proven at calagator.org for a while to ensure it works. 

You will find this release's code at the "v0.20111021" tag of the repository at https://github.com/calagator/calagator
