Andrew, is there info somewhere comparing the new stuff to current South in terms of what features differ etc? I'm particularly curious if there have been any changes to the way the orm freezing infra works.



ORM freezing is basically gone, in favour of a smarter approach where the previous state is derived from reading all of the previous migrations in to an in-memory data structure.

Andrew's blog has some great write-ups of how the new system has evolved: http://www.aeracode.org/category/django-diaries/


wow. I peeked, and that's gonna take me some time to wrap my head around. Really interesting approach. Does this mean though that if you ever fall out of favor w/ the db.migrations API and for instance make a manual change to a piece of schema, that the faked orm will be forever broken because it won't know about that change?
