開発中バージョンのリリースノート

27.0.0-24

新機能

• Add the extension extraroute-atomic to the ML2/OVN router plugin. This extension does not require any specific implementation.

• Removed support for OVN versions under v20.03.0. The "ha_chassis_group" field is expected in the "Logical_Router_Port" Northbound table. For more information, see commit ovn: Support a new Logical_Switch_Port.type - 'external'.

• An new option name trunk_enabled has been added to neutron-openvswitch-agent under OVS group. This new option can be set to False in order to disable loading the trunk extension on agent side. The default value for this option is True to keep backward compatibility with previous deployments. The recommendation is to set this option to False if you do not use the trunk extension, so that the number of queues created by the RPCServer will reduce. This can have a very good impact on large-scale scenario using RabbitMQ message broker.

アップグレード時の注意

• The WSGI script neutron-api has been removed. Deployment tooling should instead reference the Python module path for this service, neutron.wsgi.api, if their chosen WSGI server supports this (gunicorn, uWSGI) or implement a .wsgi script themselves if not (mod_wsgi).

バグ修正

• Use of DHCPv6 option 59 (bootfile-name) is now supported with OVN. See bug: 2125715.
