2025.2 Series Release Notes

19.3.0

New Features

  • Adds official support for running Bifrost on CentOS Stream 10.

Upgrade Notes

  • The default supported version of Ansible is now 10.x .

  • Because of upstream changes, Ironic can no longer be run on Python 3.9. Before upgrading to this version, ensure you’re using Bifrost on an operating system that ships a newer Python version.

Deprecation Notes

  • Support for Debian 11 Bullseye has been removed.

  • Support for CentOS Stream 9 has been removed.

  • With the upcoming support removal for Python 3.9 we can’t guarantee that CentOS Stream 9 jobs will keep working. CentOS Stream 9 support is considered deprecated and it will be removed with no further notice.

  • Since support for the ironic-inspector service is deprecated in Ironic, it is also deprecated in Bifrost, together with the enable_inspector variable. They will be removed in the 2026.1 release cycle.

    Bifrost users that set enable_inspector to true should check the ironic-inspector migration guide for information on how to migrate to the native in-band inspection in Ironic.

Bug Fixes

  • Fixes support for CentOS Stream 10 and Rocky Linux 10 by removing the dependency on sgabios for these distributions.

  • Fixes error DHCP lease file not found for dnsmasq dhcp provider. Changed wrong DHCP lease variable name in ironic.conf.j2 template in bifrost-ironic-install role.

  • Fixes Keystone start-up by providing the correct WSGI entry point.
