[orm] [usecase] Implemented the _orm.Session.bulk_insert_mappings.render_nulls
parameter for new style bulk ORM inserts, allowing render_nulls=True as
an execution option. This allows for bulk ORM inserts with a mixture of
None values in the parameter dictionaries to use a single batch of rows
for a given set of dicationary keys, rather than breaking up into batches
that omit the NULL columns from each INSERT.
[orm] [bug] Fixed issue where the __allow_unmapped__ directive failed to allow for
legacy Column / deferred() mappings that nonetheless had
annotations such as Any or a specific type without Mapped[] as
their type, without errors related to locating the attribute name.
[orm] [bug] Fixed caching bug where using the _orm.with_expression() construct in
conjunction with loader options _orm.selectinload(),
_orm.lazyload() would fail to substitute bound parameter values
correctly on subsequent caching runs.
[orm] [bug] Fixed bug in ORM annotated declarative where using a ClassVar that
nonetheless referred in some way to an ORM mapped class name would fail to
be interpreted as a ClassVar that's not mapped.
[sql] [usecase] Implemented "literal value processing" for the Interval datatype
for both the PostgreSQL and Oracle dialects, allowing literal rendering of
interval values. Pull request courtesy Indivar Mishra.
[sql] [bug] Fixed issue where using the same bound parameter more than once with
literal_execute=True in some combinations with other literal rendering
parameters would cause the wrong values to render due to an iteration
issue.
