A few releases slipped into fast-4.8, despite being tombzoned in candidate releases, 4c53c7b (#1035). Because I'd been comparing with fast-4.7 when developing the 4.7.28 blocker regexp, 2a70cf5 (#1022), those zombie releases still had edges:

$ join <(oc adm release info -o json quay.io/openshift-release-dev/ocp-release:4.7.28-x86_64 | jq -r '.metadata.previous[] | select(test("^(4[.]6[.].*|4[.]7[.][0-9]|4[.]7[.]1[1236789]|4[.]7[.]2[123])$") | not)' | sort) <(curl -s 'https://api.openshift.com/api/upgrades_info/v1/graph?channel=fast-4.8&arch=amd64' | jq -r '.nodes[].version' | sort)
4.7.10
4.7.14
4.7.15
4.7.20
4.7.24

With this commit, I'm extending the regular expression to exclude them, except for 4.7.24 which is already vulnerable to the bugs impacting 4.7.28:

$ join <(oc adm release info -o json quay.io/openshift-release-dev/ocp-release:4.7.28-x86_64 | jq -r '.metadata.previous[] | select(test("^(4[.]6[.].*|4[.]7[.][0-9]|4[.]7[.]1[0-9]|4[.]7[.]2[0123])$") | not)' | sort) <(curl -s 'https://api.openshift.com/api/upgrades_info/v1/graph?channel=fast-4.8&arch=amd64' | jq -r '.nodes[].version' | sort)
