- any/all work for Array as well as subqueries, accepted by MySQL
- Postgresql ARRAY now subclasses Array
- fixes #3516

options and USING of :ticket:`3455` released in 1.0.6,
to disable the feature for Postgresql versions < 8.2 where the
``reloptions`` column is not provided; this allows Amazon Redshift
to again work as it is based on an 8.0.x version of Postgresql.

didn't implement ``__slots__``, and therefore meant all subclasses
of that class didn't either, negating the rationale for ``__slots__``
to be in use.  Didn't cause any issue except on IronPython
which apparently does not implement ``__slots__`` behavior compatibly
with cPython.
Fixes #3494

mapped attribute on top of an :func:`.aliased` object would
resolve to the original mapper, not the :func:`.aliased`
version of it, thereby causing problems for a :class:`.Query`
that relies on this attribute (e.g. it's the only representative
attribute given in the constructor) to figure out the correct FROM
clause for the query.
fixes #3466
- apply consitency to ._parententity vs.
__clause_element__()._annotations['parententity']
in terms of aliased class, test it all.

as failing with the new 'entity' key value added to
:attr:`.Query.column_descriptions`, the logic to discover the "from"
clause is again reworked to accommodate columns from aliased classes,
as well as to report the correct value for the "aliased" flag in these
cases.
fixes #3409

changes made to the :class:`.Query` object's collection of entities
to load within the event would render in the SQL, but would not
be reflected during the loading process.
fixes #3387

and ``__declare_last__`` accessors where these would no longer be
called on the superclass of the declarative base.
