As version 0.3 gets more and more done I have started to transition into "fix" mode from "break" mode. While it may still be a while before 0.3 comes out I have started to look at all the features that will be making it into the build and when it might come out. With the list of features that I have now I am aiming for a early to mid June for an "in development" aka "experimental" release that will be available alongside version 0.2.
I also have been working on some other cool things that will likely make it into 0.3.
Train tracks and the purple conveyor 3 (x4 speed) will likely be creative only. The green Conveyor 2 (x2 speed) is added to the tech tree in iron.
