WARNING: This old version is vulnerable to the Log4Shell exploit. Do not use this in multiplayer without a patch.
Added MobSpawnESP: Highlights areas where mobs can spawn. A yellow cross indicates that mobs can spawn at night, while a red one means that mobs can spawn at any time. (MC 1.9, 1.10, 1.11, 1.11 OF, 1.12 & 1.12 OF)
AntiSpam can now block and count long messages correctly, even if the “spam counter” ends up on two lines.
Excavator will now prioritize blocks at higher altitudes. This allows it to work in survival mode without having to use the Flight hack.
Fixed Excavator ignoring tall grass, flowers, etc.
Basically just run the installer. See this tutorial for details.
Also, this should be obvious, but you do need to have a licensed copy of Minecraft Java Edition in order to use Wurst. Wurst is a cheat client, not a pirate client.
