Hello Raed, the latest version is still 2.0 alpha 2 and can be downloaded here https://github.com/FreetimeStudio/Adventure-Kit/releases/tag/2.0.0-alpha.2
If you want the absolute latest development, you can clone the 4.12 branch of the repository or download it as a zip file. Keep in mind though that this is the active development branch and might not be stable.
greetings,
FTC
