DAEXIM is a mature project now. We will continue to fix any bugs that are reported.
One new feature for consideration is filed as:
https://jira.opendaylight.org/browse/DAEXIM-14
It is dependent on:
https://jira.opendaylight.org/browse/CONTROLLER-1913
More discussion is needed before we can commit to developing the feature.
There are no other features for consideration at this point.
