Ussuri and Victoria branches are in Extended Maintenance[1]. Once any stable branch is moved to EM state then, Tempest and its plugins needs to be released[2] so that we have the compatible tags to test the EM stable branches[3]. We taged ussuri-last & victoria-last for tempest[4] but forgot to do it for the tempest plugins. Using the tag 0.15.0 hash which is compatible for tempest ussuri-last and victoria-last.
