ReleaseNotes/Liberty

OpenStack Liberty Release Notes

OpenStack Networking (Neutron)

Deprecated Plugins and Drivers

• The metaplugin is marked as deprecated in the Liberty release and will be removed from the source tree during the following release.

OpenStack Compute (Nova)

Upgrade Notes

• If you are coming from Kilo stable, please make sure you have fully upgraded to the latest release of that lineage before deploying Liberty. Due to bug https://bugs.launchpad.net/nova/+bug/1474074 versions of Kilo from before the fix will be problematic when talking to Liberty nodes.

OpenStack Telemetry (Ceilometer)

Upgrade Notes

• The name of some middleware used by ceilometer changed in a backwards-incompatible way. Before upgrading, edit the paste.ini file for ceilometer to change "oslo.middleware" to "oslo_middleware". For example using sed -ri 's/oslo\.middleware/oslo_middleware/' api_paste.ini
