[orm] [bug] Fixed issue in joined eager loading where an assertion fail would occur
with a particular combination of outer/inner joined eager loads, when
eager loading across three mappers where the middle mapper was
an inherited subclass mapper.
[orm] [bug] Fixed bug involving Select constructs, where combinations of
Select.select_from() with Select.join(), as well as when
using Select.join_from(), would cause the
_orm.with_loader_criteria() feature as well as the IN criteria needed
for single-table inheritance queries to not render, in cases where the
columns clause of the query did not explicitly include the left-hand side
entity of the JOIN. The correct entity is now transferred to the
Join object that's generated internally, so that the criteria
against the left side entity is correctly added.
[orm] [bug] An informative exception is now raised when the
_orm.with_loader_criteria() option is used as a loader option added
to a specific "loader path", such as when using it within
Load.options(). This use is not supported as
_orm.with_loader_criteria() is only intended to be used as a top
level loader option. Previously, an internal error would be generated.
[orm] [bug] Improved "dictionary mode" for _orm.Session.get() so that synonym
names which refer to primary key attribute names may be indicated in the
named dictionary.
[orm] [bug] Fixed issue where "selectin_polymorphic" loading for inheritance mappers
would not function correctly if the _orm.Mapper.polymorphic_on
parameter referred to a SQL expression that was not directly mapped on the
class.
[orm] [bug] Fixed issue where the underlying DBAPI cursor would not be closed when
using the _orm.Query object as an iterator, if a user-defined exception
