I've just uploaded 1.4.4-beta-1. The only change since alpha 10 is updated documentation. If everything works fine, I'll add the automatic upgrading and release it as the official 1.4.4 in the next few days.

It's necessary to uninstall previous 1.4.3/1.4.4-alpha version before installing this one.
