[Added] New option in nicknames.yml called on-join-random (default: false). If set to true, players will automatically get random nick on join.
[Added] Now you can disable the obfuscated function (Added in 2.9.1) in nicknames.yml, it is called invisible-obfuscated (default: true)

[Fixed] Now the obfuscated format also works for killer in kill messages.

[26.1?] Right now I'm still waiting for new version of NickAPI, until then, HrdaNick will be supporting only 1.21.x
