No upgrade is planned for 4.0. I'm actually totally against it. Having to pay extra just to upgrade a 3.x to 4.0 is fucking stupid, and for what? A stupid ass CMS that I don't need? I have a homepage already that I don't use, let alone a CMS. Plus all the styles suck. I do not see myself upgrading to this now, or anytime in the near future. I probably won't upgrade until forced to.

Plus I already have new styles planned for the new 3.8 release.
