Hi all, Given that no objection has been raised to this, I have now implemented this. All repositories in Frameworks, KDE Applications and Plasma can now only have tags starting with the convention of vN. modified by their respective release managers.
This has been implemented using a whitelist of release manager account names, which is the same system we use for controlling access to website and sysadmin repositories. While GPG was suggested as one option, we would have to maintain a whitelist anyway as well as maintain additional GPG code which seemed unnecessary given their identity has already been authenticated via their SSH Keys. Cheers, Ben
