- auto_nodetitle
- autoassignrole
- captcha
- content_complete
- content_profile
- ctools
- devel
- masquerade
- panels
- rules
So, I thought it would be interesting to go through these at this point and see how many are now Drupal 7 friendly.
- auto_nodetitle - Alpha
- autoassignrole - Dev
- captcha - Alpha
- content_complete - Dev
- content_profile - Not available.
- ctools - Alpha
- devel - Release 1.0
- masquerade - rc1
- panels - Alpha 2
- rules - Alpha 4
So there you have it. Many of the modules I depend on are in-fact available but they are in Development or Alpha states.
My advice. If you are new to Drupal and trying to build a useful web site, for the short term you should remain on Drupal 6. If you don't and try to use Drupal 7 with common modules, you'll end up pulling your hair out trying to debug modules that work perfectly in Drupal 6 today.
