as a scalar subquery such as within an IN would receive inappropriate substitutions from the enclosing query, if the same table were present inside the subquery as were in the enclosing query such as in a joined inheritance scenario. fixes #3130
to again have the chance to veto rendering, as the naming convention can make the decision that the name is "none" or not now.
constraint convention that includes ``constraint_name`` would then force all :class:`.Boolean` and :class:`.Enum` types to require names as well, as these implicitly create a constraint, even if the ultimate target backend were one that does not require generation of the constraint such as Postgresql. The mechanics of naming conventions for these particular constraints has been reorganized such that the naming determination is done at DDL compile time, rather than at constraint/table construction time. fixes #3067
parameters could be expressed in the wrong final order when CTEs were nested in certain ways. fixes #3090
to check subsequent values entries beyond the first one given for literal SQL expressions. fixes #3069
Python version < 2.6.5, working around the "no unicode keyword arg" bug as these args are passed along as keyword args within some reflection processes. fixes #3123
subclasses where direct association of the type with a :class:`.MetaData` would lead to a hang when events (like create events) were emitted on the :class:`.MetaData`. fixes #3124
type class as an argument which is internally converted to an instance, using the same convention long established by other constructs such as :class:`.Column`. fixes #3122
