Previously, you could explicitly assign None to a non-null ForeignKey
(or other) field when creating the model (Child(parent=None), etc). We
now throw an exception when you do that, which matches the behaviour
when you assign None to the attribute after creation.
Thanks to ales.zoulek@gmail.com and ondrej.kohout@gmail.com for some
analysis of this problem.

This fixes a broad class of bugs involving filters that look for missing
related models and fields. Most of them don't seem to have been reported
(the added tests cover the root cause). The exception is that this has
also fixed#9868.

This was always not working reliably (model initialization and serialization
were two of the problems). Now, it's an explicit error. Also, documented.
Fixed#10252.

Manually specifying both a OneToOneField(parent_link=True) and separate a
primary key field was causing invalid SQL to be generated. Thanks to Ramiro
Morales for some analysis on this one.

This includes a fairly large refactor of the update() query path (and
the initial portions of constructing the SQL for any query). The
previous code appears to have been only working more or less by accident
and was very fragile.

If an update only affected an ancestor model (not the child), we were
returning 0 for the number of rows updated. This could have been
misleading if the value is used to detect an update occuring. So we now
return the rowcount from the first non-trivial query that is executed
(if any). Still a slight compromise, but better than what we had.

The patch is from Russell, but I'm applying it because I want my tests to pass
again (and he doesn't see the failure).

(Simultaneously, stop django.contrib.gis using some internal attribute when
there's a perfectly good public property available to do the same thing.)

Removed a potential ambiguity when describing how multiple conditions in one
filter() call are handled.

This is like "safe", except it operates on the individual elements of a
sequence, rather than treating the whole argument as a string.

Now you can import the file storage stuff and still call settings.configure()
afterwards. There is still one import-time usage of settings in
django.contrib.comments, but that's unavoidable.

The cache tests have been failing for a long time with the db backend. This
change makes them pass again, so no test changes required here.

Allows us to reuse the same code in multiple places, avoiding new and
interesting bugs (the testing framework had a DIY version that was slightly
wrong, for example). Fixed#9833.

This permits running Django's core tests under an alternative test runner. Most
likely useful to non-CPython implementations, rather than much else (since
Django's core tests might assume things about the test runner).

Some results were inadvertently being excluded if we were ordering across a
nullable relation which itself ordering by a non-nullable relation.

In r9707 we added a preference to use Python's standard json module (Python 2.6
and beyond). However, there is also a third-party module called json that was
being picked up by accident if it was installed. It isn't API compatible, so
bad things happened. This change avoids that problem.

This avoids the problem of, for example, saving a change to the Site model in
the admin interface and then seeing the wrong instanec returned in the next
call to get_current_site().
It's still possible to end up with an inconsistent cache if update() is used to
change the Site model, but that's pretty unavoidable. It's also a slightly odd
way to update a Site model, so if you really need to do that, you can manage to
call SiteManager.clear() at the same time.
