Mindustry 5.0 is now out, with many new exciting features. These include:

Schematics. Select an area, then paste it somewhere else or save it for later use. Rotation and flipping is fully supported.



Automatic drone rebuilding. Phantom drones will now automatically replace broken blocks.



New placement controls. Edit your build queue on the fly, remove specific blocks or rotate existing ones. For planning on multiplayer servers, building can now be paused and resumed with a keybind.



Mods. Create and share your own modifications of the game through a simple json-based system. No knowledge of programming is required. Take a look at the example mod repository to see what this looks like. Documentation is currently a work in progress.
Note that modding is currently unstable. Report any bugs you find using the link in the game.
