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 a 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.
