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.
