Hi, If you want to help nova to transform its notification interface to an API then you can find your new TODO list on the wiki [1]. You can find the basic how-to information and the list of work items there. If you have any questions just ping me (gibi) on IRC or join the weekly notification subteam meeting [2]. gibi [1] https://wiki.openstack.org/wiki/Nova/VersionedNotificationTransformation [2] https://wiki.openstack.org/wiki/Meetings/NovaNotification
