Current Series Release Notes

20.0.0-15

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.

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
