While I havent documented yet (surprise !), you can also say
selectfirst() which works the old way.

selectone of a mapper does not work anymore.
I think you'll find it is still working, it is just throwing an
exception when 0 *or* > 1 rows are returned, i.e. add one f = Foo()
and an objectstore.commit() and the exception goes away, add a
second g = Foo() and the exception is thrown again as more than 1
row has been returned.
When I saw this over the weekend my first reaction was to think it
was a problem, but the function is called selectone and the new
behaviour does meet that contract, i.e give me one and only one
row. However, there is now no way to tell if the error was thrown
because there were no rows or more than one row, which is often a
useful piece of information :-).
So, what do people think- should the current behaviour remain or
should it be changed? If the latter should it revert to the
original behaviour, return None when no rows are returned and throw
the exception if > 1 are returned or something else?
