I've noticed that in the release notes for 3.0M4, it indicates that
CAY-560 has been implemented (support for outer joins).
Looking at the JIRA page for CAY-560
(http://issues.apache.org/cayenne/browse/CAY-560), it mostly seems to
talk about Expression.fromString() support.
However, reading this page
(http://cayenne.apache.org/doc/guide-to-30-features.html) indicates that
"/as of M4 there is no Expression.fromString() support)/.".
So: Is there support for outer joins in 3.0M4? If so, how do I actually
create an expression that uses outer joins, as there is no
Expression.fromString() support? Are there new ExpressionFactory methods?
