Drupal 7 Alpha 1 released

Drupal 7 Alpha 1 is now available.

I'm working about security to test as much as I can Drupal before the final release. I'm doing something like a penetration testing but it's just an hobby for me, so no professional intentions here!
However I started today and I have already found a small security hole.
It's very very low priority and absolutely not critical, it's more like a bug looking at the location I found it, but it's there and we need to patch it.

Progress about this security mission on this blog soon.
Stay tuned.
