70d5e32e13 queryset-refactor: Made the use of values() for ForeignKey fields consistent 
and documented this feature. Refs #4358.

4c4341f012 queryset-refactor: Made sure the ordering columns in a distinct() query only 
include the columns we are selecting on. This avoids some PostgreSQL problems
and leads to more efficient queries to boot. Refs #5321.

a1d160e2ea queryset-refactor: Fixed a large bag of order_by() problems. 
This also picked up a small bug in some twisted select_related() handling.

Introduces a new syntax for cross-model ordering: foo__bar__baz, using field
names, instead of a strange combination of table names and field names. This
might turn out to be backwards compatible (although the old syntax leads to
bugs and is not to be recommended).

Still to come: fixes for extra() handling, since the new syntax can't handle
that and doc updates.

Things are starting to get a bit slow here, so we might eventually have to
remove ordering by many-many and other multiple-result fields, since they don't
make a lot of sense in any case. For now, it's legal.

Refs #2076, #2874, #3002 (although the admin bit doesn't work yet).

6678de130c queryset-refactor: Fixed handling of extra(tables=...). In passing, this solves 
a duplicate table / bad SQL problem. Refs #2496.

relationships. Refs #2400.

0ebb752e89 queryset-refactor: Made all the changes needed to have count() work properly 
with ValuesQuerySet. This is the general case of #2939.

At this point, all the existing tests now pass on the branch (except for
Oracle). It's a bit slower than before, though, and there are still a bunch of known bugs that aren't in the tests (or only exercised for some backends).

240ecf0811 queryset-refactor: Fixed the optimization that potentially removes the final 
join to handle the case where a to_field attribute is given for the join.

nullable joins. This is #5324 plus a few more complex variations on that theme.

2d07a19c19 Created some tests to show ORM queries that are problematic. 
Still incomplete at the moment, but this version doesn't crash the test
framework.
