[Added] Now when /nick random <player> is executed, nick that player will get cannot be existing nick on server.
[Added] Expanded random.yml. To get new file, you need to delete the existing one.
[Added] New option max-nick-length (default: 16) in nicknames.yml, which prevents for custom nicks to be longer than selected amount.
[Added] API for plugin → Useful for developers. For more information look on HrdaNick WIKI
[Added] New Command /nick whois <player> for admins to get the original nickname of nicked player.

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