- [feature] "scalar" selects now have a WHERE method
to help with generative building. Also slight adjustment
regarding how SS "correlates" columns; the new methodology
no longer applies meaning to the underlying
Table column being selected. This improves
some fairly esoteric situations, and the logic
that was there didn't seem to have any purpose.
- [feature] Some support for auto-rendering of a
relationship join condition based on the mapped
attribute, with usage of core SQL constructs.
E.g. select([SomeClass]).where(SomeClass.somerelationship)
would render SELECT from "someclass" and use the
primaryjoin of "somerelationship" as the WHERE
clause. This changes the previous meaning
of "SomeClass.somerelationship" when used in a
core SQL context; previously, it would "resolve"
to the parent selectable, which wasn't generally
useful. Related to [ticket:2245].
