oc 1.4, which is available from github is not compatible with the lastest CDK 2.3 (it's only compatible oc 1.3). Futhermore there are specific enterprise oc binaries which follow the OSE versioning scheme 3.2, 3.3 etc. making it hard for the user to know what oc he should use.
Our preferences offer a link to the github releases but there's no info nor logic that makes sure that the user will use compatible combinations (oc 1.4 with CDK 2.3, oc 1.2 with CDK 2.3 etc.)
