Drupal 7.0 Alpha 2 has been released

"We've also fixed a number of issues since the previous alpha, most importantly one that caused all files to be deleted after six hours."

When i read the title i wondered if this was HN material. This quote makes it worthy i guess :)

Actual notice has more information: http://drupal.org/drupal-7.0-alpha2

Also, this is just a copy+paste from drupal.org.

Any one tried the RDF support?
