So for Openstack, we would mostly worry about code that is doing
things oddly in some unexpected way, however all the Openstack code
I've seen tends to be very ORM centric and uses the ORM very
conservatively so I don't anticipate any problems. I would note that
some silently-/ quasi- failing use cases for query.update() and
query.delete() now raise exceptions in 1.0. They both emit warnings
in 0.9 but I just checked and apparently one of these warnings is only
in the as-yet unreleased 0.9.10. I've just added an extra migration
note for one of these which appeared to be missing in the migration
document (as of this writing it should be up on RTD within an hour).
That said, the document which tries to capture everything that might
be surprising is at
http://docs.sqlalchemy.org/en/rel_1_0/changelog/migration_10.html.
here are those:
http://sqlalchemy.readthedocs.org/en/rel_1_0/changelog/migration_10.html#query-update-query-delete-raises-if-used-with-join-select-from-from-self
http://sqlalchemy.readthedocs.org/en/rel_1_0/changelog/migration_10.html#query-update-with-synchronize-session-evaluate-raises-on-multi-table-update
