* The name of some middleware used by ceilometer changed in a backward incompatible way. Before upgrading, edit the <code>paste.ini</code> file for ceilometer to change <code>oslo.middleware</code> to <code>oslo_middleware</code>. For example, using <nowiki>sed -ri 's/oslo\.middleware/oslo_middleware/' api_paste.ini</nowiki>
* The notification agent is a core service to collecting data in Ceilometer. It now handles all transformations and publishing. Polling agents now defer all processing to notification agents, and must be deployed in tandem.
