I would like to know if auto-update option will be implemented in the future so that we don't need to download setup file for each update.

Hopefully when we shift to Github I can implement a update feature, but currently you can overwrite existing MC build, or just copy your settings folder to the new MC.

The second option does allow you to to fall back to a working MC if there are any issues with the new build.
