Looks to me like simple typo(s)... Thread Header (sb. 1.1.4) and in the notes OP (based on sb. 1. 1.3)... I agree 1.4 and 1.3 is somewhat misleading... downloaded instance is actually v1.1.4
Allow me to rephrase: If you've compiled the v1.4 release all by yourself, then kindly submit a pull request to the Corefig GitHub repo for the sake of community development. Otherwise, please mention the name of the original creator.
