New Charm Features
Neutron Apparmor
openstack-dashboard + Keystone v3
The openstack-dashboard charm now supports the keystone v3 API. To enable this feature the openstack-dashboard charm needs to be related to a database backend for storing session data.

External Network Update
The neutron-gateway charm has been updated to use "new" style external networks when ext-port is not set.
Previously only a single external network could exist on a neutron-gateway unit. Now multiple networks can exist and also complex network configurations can be setup such as VLANs. It is also possible to use the same physical connection with different segmentation IDs for both internal and external networks, as well as multiple external networks.
eg
Alternative configuration with two external networks, one for public instance addresses and one for floating IP addresses. Both networks are on the same physical network connection (but they might be on different VLANs, that is configured later using neutron net-create).
neutron-gateway:
bridge-mappings: physnet1:br-data
data-port: br-data:eth1
neutron-api:
flat-network-providers: physnet1
neutron net-create --provider:network_type vlan \
--provider:segmentation_id 400 \
--provider:physical_network physnet1 --shared external
neutron net-create --provider:network_type vlan \
--provider:segmentation_id 401 \
--provider:physical_network physnet1 --shared --router:external=true \
floating
neutron router-gateway-set provider floatingThis replaces the previous system of using ext-port, which always created a bridge called br-ex for external networks which was used implicitly by external router interfaces.

Upgrading
General
Please ensure that the keystone charm is upgraded first.
To upgrade an existing deployment to the latest charm version simply use the 'upgrade-charm' command, e.g.:
juju upgrade-charm cinder
Note: The networking endpoint in keystone has been renamed from quantum to neutron in-line with upstream name changes.
Deprecation Notices
Minimum Juju version
OpenStack Charm CI testing no longer validates the OpenStack charms against versions of Juju (< 1.24) which don't have the leader election feature, used to determine leadership between peer units within a service.
Legacy leadership support will be removed from the charms over the next few development cycles, so please ensure that you are running on Juju >= 1.24.
Port MTU Settings
Using network-device-mtu config option with the neutron-api charm to set MTU on physical nics is deprecated on trusty deployments and will not work on xenial deployments. The prefered method is to use MAAS to set MTU.
neutron-gateway shared-db relation removed
The neutron-gateway shared-db relation has been removed. Please update bundles to reflect this.
Known Issues
No Ceilometer alarms on Mitaka
