Sonar v2.1.48

Sonar is a lightweight and effective anti-bot plugin for Velocity, BungeeCord, and Bukkit.
  • Improve the collision check #360
    • Add more configurable block types (ENCHANTMENT_TABLE, TRAPDOOR, STONE)
    • Fix a bug where the XP bar was shown to players in creative mode
  • Implement missing "fell through blocks" check
  • Fix verification.currently-preparing not being used
  • Fix Bedrock players not being able to be transferred #356
  • Implement Bukkit Support #347
    • Instead of replacing existing pipelines, Sonar now removes every pipeline and adds the necessary ones, therefore saving RAM and CPU usage by minimizing the handlers in the channel.
  • Allow general.max-online-per-ip to be 0

Sonar will only work on standalone Bukkit servers that are not behind a proxy (e.g., BungeeCord or Velocity). If you use a proxy, please install Sonar on the proxy instead of the backend server
