2025.1 Series Release Notes

16.1.0-4

Bug Fixes

  • Fixes delayed metrics processing in services using eventlet, caused by mixing a native thread with an eventlet-patched queue. See bug 2098714 for details.

  • Fixes a bug where calling some OpenStack utilites, such as nova-manage, within podman containers would fail when using Queue Manager. LP#2091703

16.1.0

New Features

  • Add a new option named kombu_reconnect_splay under oslo_messaging_rabbit that could be used to add an extra random delay before any reconnection when a recoverable error occur. This delay is set to 0 by default so the original behavior is not changed.

Deprecation Notes

  • Eventlet usages are deprecated and the removal of Eventlet from OpenStack is planned, for this reason the Eventlet executor is deprecated. Start migrating your stack to the threading executor. Please also start considering removing your internal Eventlet usages.

  • The executor parameter of the MessageHandlingServer class is now deprecated and planned for removal. The Eventlet executor is deprecated. Only the threading executor will remains available so the executor parameter is useless.

15.0.0

Upgrade Notes

  • The AMQP1 driver, which was deprecated in 14.1.0 was removed, due to limited usage and lack of support on recent distributions. Use any of the other supported driver, such as RabbitMQ or Kafka.

  • Support for Python 3.8 has been removed. Now the minimum python version supported is 3.9 .
