Current Series Release Notes¶
The database migration engine used by Glance for database upgrades was changed from SQLAlchemy Migrate to Alembic in the 14.0.0 (Ocata) release. Support for SQLAlchemy Migrate has now been removed. This means in order to upgrade from a pre-Ocata release to Xena or later, you must upgrade to Wallaby or earlier first.
Glance now has per-tenant quota support based on Keystone unified limits for resources like image and staging storage, among other things. For more information about how to configure and use these quotas, refer to the relevant section of the Administrator Guide.
