Perhaps the most eagerly awaited lately by the users of Drupal is the Drupal 7 RC1. If Drupal 7 has reached RC version, then:
- The API is frozen.
- All markup is frozen.
- The UI is frozen.
- The theme system is frozen.
- All strings are frozen.
- Drupal 7.0's release is imminent.
I really waited for Drupal 7 RC1, because with the release of RC version, so I do not need to change some of my themes system every new version released since the theme system is frozen.
And finally the Drupal 7 RC1 released!. You can download it here.
