So yes, this is beta3. With luck there will not be a beta4, just a 1.6 that follows it; but I’ve already had 3 critical bugs come up. Mostly because the long gap between 1.5 and 1.6 saw a LOT of code changes/improvements and, naturally, I didn’t test them well enough. (This is why I called it a beta. I knew I didn’t test it well enough).

Feel free to give it a try:

For Drupal 5.x: download — release notes

For Drupal 4.7.x: download — release notes

Also, if you didn’t grab the first beta, check out ITS release notes which are a bit longer:
