We do not want site admins creating nor editing fixVersions as we have standard ones which should be used across the instances.
But based on our initial investigation, it looks like restricting the site admins from creating fixVersions will also remove the flexibility for teams to self-manage within their JIRA projects, as the project admins (SMs, POs) would no longer have the ability to update User Roles & Permissions, or any other project configuration. The ability to create a fixVersion is tied to the "Administer Project" permission. We want project admins & their teams to self manage.
Is there a way to restrict the creation of fixVersions within Jira projects solely to the Jira admins?
