To prevent unbounded size growth, we want to delete older nightly and beta manifests from master branch regularly. Users of old nightly and beta toolchains can still access from the `before/` tags, but these tags will not receive patch updates anymore. Currently cut-off can only be deployed manually. Stable versions are not affected and are all kept currently.
