[Zope-dev] Re: zope.sqlalchemy dependencies does not respect setup.py dev egg

[Laurence Rowe]

zope.sqlalchemy specifically requires a SessionExtension hook added in
0.4.7 and 0.5.0b3 to fix a bug that came to light in porting dobbin
over to use it:

"New objects added to a session did not
cause a transaction join, so were not committed at the end of the
transaction unless the database was accessed. SQLAlchemy 0.4.7 or
0.5beta3 now required."

Other than that nothing really changed since 0.2, you should be able to 
just use that.
