What this means for our modding community

Do you like to mod Java, tinker with builds, or take deep dives into Minecraft’s code? Then this article is for you!

For a long time, Java Edition has used obfuscation (hiding parts of the code) – a common practice in the gaming industry. Now we’re changing how we ship Minecraft: Java Edition to remove obfuscation completely. We hope that, with this change, we can pave a future for Minecraft: Java Edition where it’s easier to create, update, and debug mods.
