Hello Manila, I noticed there were some discussions about api extensions in the past few weeks. Looks like nova has similar discussions too. "Each extension gets a version", if my understanding about the api extension discussion purpose is correct. Not sure if you already known it or not. I'm no expert here, so just FYI: https://wiki.openstack.org/wiki/Nova/ProposalForAPIMicroVersions http://lists.openstack.org/pipermail/openstack-dev/2014-September/046482.html They have some discussions about where/how to add the new API functionality recently: http://lists.openstack.org/pipermail/openstack-dev/2015-March/058493.html Thanks. -chen -------------- next part -------------- An HTML attachment was scrubbed...
