+prelude: >
+    6.0.0 is the final release for Ocata.
+    It's the first release where release notes are added.
+features:
+  - Fujitsu Neutron plugin for FOS support.  Users can deploy
+    Neutron with this plugin by using
+    environments/neutron-ml2-fujitsu-fossw.yaml environment file.
+  - Expose InstanceDiscoveryMethod parameter to configure Ceilometer
+    method used to discover instances running on compute node.
+    Default value to 'libvirt_metadata'. Allowed values are 'naive',
+    'libvirt_metadata' and 'workload_partitioning'.
+  - Make ServiceNetMap support custom network names.
+    Note that operators will still be expected to pass any ServiceNetMap
+    overrides with the "new" network name, e.g whatever NetName specifies,
+    otherwise environment files could get very confusing.
+  - Nova Placement API support.  As this new service is required, deploy it
+    by default in WSGI with Apache, like other API services.
+  - Cinder pass-through iSER backend support.
+  - etcd composable services, used by networking-vpp ML2 driver as the
+    messaging mechanism.
+  - Allow to configure cron parameters for Cinder, Heat, Keystone and Nova
+    crontabs.
+  - Export NovaDefaultFloatingPool parameter to configure the default pool
+    of floating IP addressed available. Default to 'public' for backward
+    compatibility.
+  - Bump Heat Templates to 'ocata' version, to match Heat requirements.
+  - Configure OVS agent firewall driver only if NeutronOVSFirewallDriver
+    is set.
+  - Expose RbdDefaultFeatures parameter to configure the default features
+    enabled when creating a block device image.
+    Only applies to format '2' images. Set to '1' for Jewel clients using
+    older Ceph servers.
+  - Cinder HPELeftHandISCSIDriver backend support.
+  - Pacemaker stopped to manage Ceilometer, Cinder API,
+    Cinder Scheduler, MongoDB, Glance, Gnocchi, Heat, Apache, Memcached,
+    Neutron, Nova and Sahara.
+  - Ceph MDS service support. Service can be enable with
+    environments/services/ceph-mds.yaml environment file.
+  - Expose HeatConvergenceEngine and HeatMaxResourcesPerStack parameters
+    to configure Heat.
+  - Add pre-network hook and example showing config-then-reboot.
+  - Expose LibvirtEnabledPerfEvents parameter in Nova Compute service.
+    Default to an empty array.
+    This is a performance event list which could be used as monitor.
+  - Increase libvirt/qemu.conf max_files to 32768 and max_processes to
+    131072.
+  - Split OVN northd and ml2 plugin, so we can deploy OVNDBs and Northd
+    services on different nodes.
+  - Add hook to generate metadata from service profiles.
+    This is useful for nova vendordata plugins that can parse said metadata.
+  - Expose EventPipelinePublishers to Ceilometer and set the default to
+    'notifier://?topic=alarm.all'.
+  - Add Panko service support. This service is not enabled by default. Use
+    environments/services/enable-panko.yaml to include it in your deployment.
+  - Add EC2-API composable service support.
+upgrade:
+  - Update OpenDaylight deployment to use networking-odl v2 as a mechanism
+    driver.
+deprecations:
+  - Glance Registry service has been removed and Glance API v2 is now deploy
+    by default. Glance API v1 is not supported anymore in TripleO.
+  - Remove CeilometerStoreEvents parameter, which has been removed
+    in Ceilometer.
+  - Ceilometer API service is deprecated and will be removed in a future
+    release. If you would like to disable it, use
+    environments/services/disable-ceilometer-api.yaml environment file.
+  - Removes deprecated OpenDaylight L2 only deployments.
+    Deploying ODL without L3 DVR is no longer supported.
+security:
+  - Disallow iframe embed in Horizon configuration to prevent dashboard being
+    embedded within an iframe and exposed to Cross-Frame Scripting (XFS)
+    vulnerability on legacy browsers.
+  - Allow management of enforce_password_check in Horizons configuration to
+    display an 'Admin Password' field on the Change Password form to verify that
+    it is indeed the admin logged-in who wants to change the password.
+  - Allow management of disable_password_reveal in Horizon, to remove the
+    password reveal option.
+  - Enable secure_proxy_ssl_header option in Horizons configuration to take
+    X-Forwarded-Proto header into account when forming URLs.
+fixes:
+  - Fixes `bug 1645898

+    the right address, where RabbitMQ is listening too.
+  - Fixes `bug 1652184
+    <https://bugs.launchpad.net/tripleo/+bug/1652184>`__ so swap partitions
+    can be handled from an environment file thanks to AllNodesExtraConfig.
+  - Add retry to RHEL registration, useful when having network outages during
+    registration.
+  - Fixes `bug 1651476
+    <https://bugs.launchpad.net/tripleo/+bug/1651476>`__ so firewall rules
+    are created for Opendaylight API service.
