Xena Series Release Notes

11.0.0

Upgrade Notes

• Checks specific to the DB2 database have been removed. This database has not been supported by any OpenStack project for many years.

• The check_foreign_keys helper of the oslo_db.sqlalchemy.test_migrations.ModelsMigrationsSync base test class has been removed. This was deprecated in 1.4.1 as alembic now supports this capability.

• The _walk_versions, _migrate_down, and _migrate_up methods of the oslo_db.sqlalchemy.test_migrations.ModelsMigrationsSync base test class have been removed. These were deprecated in 0.5.0 in favour of their non-private equivalents, walk_versions, migrate_down, and migrate_up respectively.

Deprecation Notes

• The oslo_db.concurrency.TpoolDbapiWrapper class and supporting [database] use_tpool config option are now deprecated. This feature never graduated from experimental status and is slated for removal due to lack of maintenance and test coverage. Users should switch to oslo_db.api.DBAPI.from_config and remove references to the deprecated config option from their documentation.
