     https://www.keycloak.org/2021/12/cve.html
 
 Not all versions are affected but they're suggesting that people upgrade soon.
+
+As per usual, this upgrade didn't go too smoothly and I ended up having to
+undeploy and deploy the new versions. The healtcheck kept failing on the new
+instance when trying to deploy alongside the existing old version. Idk, some
+docker weirdness.
+
+No app data errors discovered after upgrade.
