Massive changes, the entire plugin was refactored. No, you didn't miss 1.3.0, this is the follow up to 1.2.2.

Breaking Changes:

• Plugin is now called "Raycasted Entity Occlusions" instead of "Raycasted Entity Occlusion"
  • This is just a grammar thing lol, but it means the config folder name has changes too, which is good because
• All config options have changed
  • The existing ones have been renamed and new ones have been added. I recommend starting with a fresh config, it's not worth trying to transfer your old values. Just generate a fresh config and edit the values as you see fit, or you can use the
• Reworked commands
  • The command is now /raycastedentityocclusions (alias /reo)
  • Behind the scenes, it now uses the new Brigadier API instead of the outdated Bukkit method
  • One of the subcommands, /reo set allows you to change config values from the chat/console
• Proper multithreading
  • Instead of making unsafe async worldstate checks, the plugin now routinely snapshots all loaded chunks and checks the snapshots when raycasting. A basic test seems to show a slight performance increase, but more importantly it is no longer performing unsafe actions
• Engine mode changes
  • There are now only two engine modes, both with a new "piercing" feature. The first, 1, is a single raycast from the player to the entity. 2 runs the same cast as 1, but also predicts the player's future location and runs a cast from there. This helps account for players with higher ping.
  • "Piercing" (controlled by max-occluding-count) is the number of solid blocks a raycast must pass through before being stopped. This helps with showing entities which will soon be visible.
• only-cull-sneaking-players is now a fully functional feature
