One of the barriers for entry for Kane's Wrath modding has been the sheer number of official and unofficial versions of its fan-made mod SDK, WrathEd, including the availability of its links. Today, its creator @Lauren (a.k.a. Darth Jane, among many other names) decided to publish an updated version labeled 1.10 to GitHub with its source code and pre-compiled package available to everyone. While modders for Tiberium Wars and Kane's Wrath have been making their own definitions to fix the issues in the existing ones without direct feedback to her, some of them are incorrect but pull requests are welcome. This is the only release of the tool that will get Lauren's tech support, all others are hereby considered obsolete.
