Yes, but 1.5 claimed only "experimental support", adding that they thought it probably would work all right but didn't want to recommend Python 3 for production yet. The unqualified "yes, we now consider it ready and can recommend Python 3 for production," was promised for Django 1.6. They probably have achieved that goal, but the fact that there is no mention of it anywhere in a document that mentions so many other things suggests that "for the first time, we can now recommend the use of Python 3 for production" isn't something they think their target market cares about as much as the several dozen other "issues" they DID mention.
