i would like to have the latest version of unity-2d installed on my system. i can see some references to a version 6 in some places e.g. http://changelogs.ubuntu.com/changelogs/pool/main/u/unity-2d/
but all i can grab from the repos is version 5.14, after that it's related as dummy packages.
i would like to put my hands in the latest unity-2d code available. please help me
