Current Series Release Notes

20.0.0-3

Upgrade Notes

• Ubuntu 22.04 “Jammy” is no longer a supported operating system for running Bifrost. Please use 24.04 “Noble” instead.

• The default Ubuntu deployment image release is now Noble. If you rely on the upstream deploy image defaults with upstream_deploy_image_distribution: ubuntu, update any explicit upstream_deploy_image_release overrides that were set to jammy.

20.0.0

New Features

• Added support for testing the new standalone Ironic networking service. When enable_ironic_networking is set to True, the standalone networking service is launched alongside the main Ironic service using the ironic-networking networking driver. Generated inventory files now include port and driver information to utilize this new functionality. This feature enables testing of advanced network configuration capabilities in standalone Ironic deployments.

Known Issues

• When testing standalone Ironic networking functionality, if test_vm_use_static_local_link_connection_info is set to false, then manual inspection must be performed on nodes prior to deployment to ensure local_link_connection information is available for switch port identification. Without this information, nodes may be silently provisioned on incorrect VLANs.

• The OVS bridge type must be used for testing this functionality.
