I just released the Data Generator 3.0.0 beta. You can find it here:

The host is PAINFULLY slow right now, but the code seems pretty solid at this point.

Over the new couple of weeks my focus is going to be on:

- finishing the Developer Doc (80% there!)
- getting the JS and PHP Doc up to date.
- working on the new website.

All the best!
