- Fixed a few edge cases which arise in the so-called "row switch"

2014-05-29T00:01:49+00:00

scenario, where an INSERT/DELETE can be turned into an UPDATE.
In this situation, a many-to-one relationship set to None, or
in some cases a scalar attribute set to None, may not be detected
as a net change in value, and therefore the UPDATE would not reset
what was on the previous row.   This is due to some as-yet
unresovled side effects of the way attribute history works in terms
of implicitly assuming None isn't really a "change" for a previously
un-set attribute.  See also :ticket:`3061`. fixes #3060

- Fixed bug in INSERT..FROM SELECT construct where selecting from a

2014-05-25T18:09:08+00:00

UNION would wrap the union in an anonymous (e.g. unlabled) subquery.
fixes #3044

- Added the ``hashable=False`` flag to the PG :class:`.HSTORE` type, which

2014-05-25T17:58:31+00:00

is needed to allow the ORM to skip over trying to "hash" an ORM-mapped
HSTORE column when requesting it in a mixed column/entity list.
Patch courtesy Gunnlaugur Þór Briem.  Fixes #3053

- Fixed bug in subquery eager loading where a long chain of

2014-05-25T17:46:01+00:00

eager loads across a polymorphic-subclass boundary in conjunction
with polymorphic loading would fail to locate the subclass-link in the
chain, erroring out with a missing property name on an
:class:`.AliasedClass`. fixes #3055

- Fixed bug in SQLite join rewriting where anonymized column names

2014-05-25T15:32:36+00:00

due to repeats would not correctly be rewritten in subqueries.
This would affect SELECT queries with any kind of subquery + join.
fixes #3057

- Fixed bug where the :meth:`.Operators.and`,

2014-05-24T18:42:21+00:00

:meth:`.Operators.__or__` and :meth:`.Operators.__invert__`
operator overload methods could not be overridden within a custom
:class:`.TypeEngine.Comparator` implementation.
fixes #3012
