Xena Series Release Notes


Upgrade Notes

  • If kombu_reconnect_delay is specified in the [oslo_messaging_rabbit] section, ensure that it is less than 5.0, the value of ACK_REQUEUE_EVERY_SECONDS_MAX

Bug Fixes

  • Increased ACK_REQUEUE_EVERY_SECONDS_MAX to resolve issues with rabbitmq HA failover.


Bug Fixes

  • As a fix for bug 1917645 the rabbit backend is changed to use the [oslo_messaging_notifications]retry parameter when driver tries to connect to the message bus during notification sending. Before this fix the rabbit backend retried the connection forever blocking the caller thread.


New Features

  • Introduce support for sending rpc client metrics to oslo.metrics.
    This feature can be enabled by setting a configuration parameter:

    [oslo_messaging_metrics] metrics_enabled = True # default is false
