Unsupported bytecode version with HashLink v1.3 and Haxe 3.4.4

I have downloaded the hashlink v1.3 and haxe v3.4.4. And tried to compile my first hashlink project. I am getting a error Unsupported bytecode version. I am using HaxeDevelop to create the project and compiling it. Any optional parameters I need to pass in while compiling? I am in Win 10.

HashLink 1.3 and recently released 1.4 requires Haxe nightly builds available on http://build.haxe.org
