This release comes with some internal improvements and some formalities since the last release.
Also, targeting/supporting 1.16.5 with this release (tested for 1.16.5 on Spigot).
If you're still using Bukkit, I strongly recommend you to switch to Spigot.
While this plugin should still work with Bukkit, I now only test for Spigot.
While this plugin targets Java 1.8, I did test it with Java 11.
If you test it on another server or Java version, let me know your findings!
