Zed 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.


Upgrade Notes

  • The [oslo_messaging_rabbit] heartbeat_in_pthread config option defaults to False again. For wsgi applications it is recommended to set this value to True but enabling it for non-wsgi services may break such service. Please check https://bugs.launchpad.net/oslo.messaging/+bug/1934937 for more details.


New Features

  • Add quorum configuration x-max-in-memory-length, x-max-in-memory-bytes, x-delivery-limit which control the quorum queue memory usage and handle the message poisoning problem


New Features

  • Adding a new option, [oslo_messaging_rabbit] ssl_enforce_fips_mode, to the rabbitmq driver to enforce the OpenSSL FIPS mode if supported by the version of Python.

Security Issues

  • We are now able to enforce the OpenSSL FIPS mode by using [oslo_messaging_rabbit] ssl_enforce_fips_mode.
