Four years. That’s how long it’s been since Microsoft acquired Minecraft developer Mojang. A lot has happened in those four years — Minecraft on Switch, malware in Minecraft, open-sourcing some of the code… wait, what was that last one?Yesterday, Microsoft and Mojang released two parts of Minecraft’s Java code in library form, so that “anyone can pick them up and use them in their own game”, according to Lead Engineer Nathan Adams.

Thanks to being MIT-licensed, anyone is free to “contribute and … help improve our game engine” and, by the same token, use the code freely in other projects, commercial or otherwise.
