orm
* An ArgumentError with more detail is now raised if the target
parameter for Query.join() is set to an unmapped object. Prior
to this change a less detailed AttributeError was raised. Pull
request courtesy Ramon Williams. References: #4428
* Fixed issue where using a loader option against a string attribute
name that is not actually a mapped attribute, such as a plain
Python descriptor, would raise an uninformative AttributeError;
a descriptive error is now raised. References: #4589
engine
* Fixed issue where a non-string object sent to SQLAlchemyError or a
subclass, as occurs with some third party dialects, would fail to
stringify correctly. Pull request courtesy Andrzej Bartosiński.
References: #5599
* Repaired a function-level import that was not using SQLAlchemy’s
standard late-import system within the sqlalchemy.exc module.
References: #5632
sql
* Fixed issue where the pickle.dumps() operation against Over construct
would produce a recursion overflow. References: #5644
* Fixed bug where an error was not raised in the case where a column()
were added to more than one table() at a time. This raised correctly
for the Column and Table objects. An ArgumentError is now raised when
this occurs. References: #5618
postgresql
* The psycopg2 dialect now support PostgreSQL multiple host connections,
by passing host/port combinations to the query string.
