[orm] [bug] Fixed bug where a cascade such as "delete-orphan" (but others as well)
would fail to locate an object linked to a relationship that itself
is local to a subclass in an inheritance relationship, thus causing
the operation to not take place.
[schema] [bug] An
ArgumentErroris now raised if a
ForeignKeyConstraintobject is created with a mismatched
number of "local" and "remote" columns, which otherwise causes the
internal state of the constraint to be incorrect. Note that this
also impacts the condition where a dialect's reflection process
produces a mismatched set of columns for a foreign key constraint.
- [postgresql] [bug] Added "autocommit" support for GRANT, REVOKE keywords. Pull request

[mysql] [bug] Removed an ancient and unnecessary intercept of the UTC_TIMESTAMP
MySQL function, which was getting in the way of using it with a
[mysql] [bug] Fixed bug in MySQL dialect regarding rendering of table options in
conjunction with PARTITION options when rendering CREATE TABLE.
The PARTITION related options need to follow the table options,
whereas previously this ordering was not enforced.
[oracle] [bug] Fixed bug in cx_Oracle dialect where version string parsing would
fail for cx_Oracle version 6.0b1 due to the "b" character. Version
string parsing is now via a regexp rather than a simple split.
[bug] [ext] Protected against testing "None" as a class in the case where
declarative classes are being garbage collected and new
automap prepare() operations are taking place concurrently, very
infrequently hitting a weakref that has not been fully acted upon
