Hello, As aggreed on IRC meeting, Kolla Ussuri and Victoria deliverables (Kolla, Kolla-Ansible, Kayobe) are going EOL. [1] Wallaby remains in extended maintenance. Xena, Yoga and Zed are our current stable releases. Ussuri and Victoria branches were in Extended Maintenance for a some time, Kolla community does not have resources to support those branches actively. Moreover Ussuri and Victoria were the last releases that support CentOS 8 which is also EOL. All changes to those branches have been abandoned.
