Drupal just might be the perfect software for me, however I have a few questions:
Why are you releasing version of 4.x and 5.x simultaneously? I'm assuming that perhaps this was just a security patch and for some strange reason you still support the 4.x software? But 5.x is the latest, best, and most stable release?
And my second question, if I'm in the process of creating a site should I wait for Drupal 6.x? How far off is it? Could I just use the current RC or is it not stable enough? Could I just use 5.x and easily upgrade to 6.x?
