Current Series Release Notes

20.0.0-24

Upgrade Notes

  • Backup files are now stored in timestamped directories and have new filenames. This does not affect restore, as Kolla Ansible does not support automated restore; users perform restores manually. A new full backup is recommended after upgrade to ensure incremental backups work correctly.

  • Upgraded ProxySQL to version 3.0.x.

  • Debian container image builds now use Epoxy (2025.1) repositories of Debian OpenStack.

  • Debian container image builds now use bookworm suite for RabbitMQ installation.

  • Update OpenSearch and OpenSearch Dashboards to version 3.x.

  • rabbitmq version has been updated to 4.1.

Deprecation Notes

  • The OVN exporter has been removed with immediate effect since 1) it isn’t used in Kolla Ansible and 2) the source repo was archived in Dec 2024.

Bug Fixes

  • Fixes incremental MariaDB backups by switching to directory-based base backups, following official Mariabackup recommendations. LP#2111620

  • Ensures Kolla uses only configured APT mirror on Ubuntu for full source control. LP#2112140

  • Fixes set_configs.py not detecting removed config files during –check, which prevented container restart when needed. LP#2114173

  • Fix using Cinder as Glance image store when Cinder uses a FC or iSCSI backend by adding the missing lsscsi package to glance-api. LP#2111828

  • Fix neutron-l3-agent image builds on Rocky Linux by removing dibbler-client dependency. The package is no longer used in Neutron. LP#2112575
