QuickEnderChest v2.0.0 Release Notes

🆕 New Features

• Permission-based Ender Chest Access Control
  Players now need to have an Ender Chest in their inventory to open it via the /ec command by default. This behavior can be overridden using the new permission node:

  • quickec.open.ignore_inventory – Allows players to open their Ender Chest regardless of inventory contents.

• Right-Click Ender Chest Opening
  Players can now open their Ender Chest by right-clicking while holding one in hand. Sneaking while right-clicking will place the Ender Chest instead. The following permission node controls this feature:

  • quickec.open.click – Allows players to open the Ender Chest with right-click.

🔄 Updates

• Updated to 1.20.4 API
  The plugin has been updated to support the Minecraft 1.20.4 API, ensuring compatibility with the newest server versions.

Note: I am not sure about backward compatibility below 1.19.
