This update is for Spigot/Minecraft 1.17.1 - 1.20.1, and has been compiled with Java 17 and Spigot API 1.20.1.
This is a minor change to prove compatibility with 1.20.1, adds a new permission to control use of the 'autojoin' command, and some additional Japanese translations provided via Crowdin. Thanks to soushimiyatani0210 for the translations.
