Open Stack

Operators,

We did not receive any feedback that dropping Keystone driver versioning would negatively impact anyone.  Thus, the Keystone team met yesterday and decided to drop support for driver versioning.  However, we will continue to support current legacy drivers.

Moving forward though, what this means is, that if a Keystone driver interface changes and you have a custom implementation, you would need to upgrade your custom drivers to meet the new interface in order to upgrade OpenStack.  Let us know if you have any questions.

Regards,
Ron

Subject: Keystone to drop support for driver versioning…

Operators,

Currently in Keystone, we support driver versioning, where we support a driver interface for at least one version back.  However, this has become burdensome in terms of maintenance and some of us are questioning the value of supporting this.  Thus, we have a proposal in Newton to drop support for driver versioning.

Under the new proposal, if a driver interface changes, we would clearly document it in the release notes and in order for you to upgrade, you would need to upgrade your custom drivers to meet the new interface.

That being said, before deciding on this, we are looking for feedback on whether or not this would significantly impact you.

Regards,
Ron
