Christ, Django is changing too fast. I recently upgraded from 1.2 to 1.3 and it's still way obsolete.

Django 1.3 was released back in March of 2011. That's more than two years ago! Were you waiting on some sort of third party package or something?

I recently updated an older project from 1.2 to 1.5 and it was quite a bit of work.

1.3 -> 1.4 was trivial AFAIR. 1.4 -> 1.5 may need some more work if you depended a lot on function-based generic views.
