--- prelude: > - The ``s3`` store driver has been removed. upgrade: - The latest release of glance_store library does not have the support for the ``s3`` driver. All code references of the same have been removed from the library. As this release of Glance uses the updated glance_store library, you will find the ``s3`` driver support removed from Glance too. For example the Glance image location strategy modules no longer offer the ``s3`` driver support.
