Fixed a regression from 0.7 caused by this ticket, which

2013-05-13T20:13:15+00:00

made the check for recursion overflow in self-referential
eager joining too loose, missing a particular circumstance
where a subclass had lazy="joined" or "subquery" configured
and the load was a "with_polymorphic" against the base.
[ticket:2481]

- moderinzed the docs for the foreign_keys parameter a bit,

[ticket:2725]

- Fixed a regression from 0.7 where the contextmanager feature

2013-04-30T14:02:49+00:00

of :meth:`.Session.begin_nested` would fail to correctly
roll back the transaction when a flush error occurred, instead
raising its own exception while leaving the session still
pending a rollback.  [ticket:2718]

Fixes to the ``sqlalchemy.ext.serializer`` extension, including

2013-04-26T19:51:29+00:00

that the "id" passed from the pickler is turned into a string
to prevent against bytes being parsed on Py3K, as well as that
``relationship()`` and ``orm.join()`` constructs are now properly
serialized. [ticket:2698] and some other observed issues.

- further cleanup. in particular, the left clause is never None. But we still

2013-04-25T18:44:37+00:00

can have errors when we do the auto-join, these are both covered in test_joins

we can always adapt to right also. suppose if right

2013-04-25T18:29:48+00:00

were an alias of a table, should add tests for that.

cleanup

2013-04-25T18:13:13+00:00

everything passes with this!!!!!!! holy crap !!!!! and its the simplest of all

2013-04-25T17:54:40+00:00

- attempt to replace the whole idea of "join_to_left" with a more

2013-04-24T22:58:09+00:00

fundamental and general purpose heuristic.   this initial approach
has about 60 tests failing but seems to have gone pretty far

- merge exists() patch + changelog
