In this update NoxesiumAPI has become a Paper plugin meaning that it will only work on Paper (or forks of Paper) servers on 1.21.8+. This is due to the changes around the trident api on Paper only being added since that version.

Changelog

• Switched to Paper plugin
• Updated to Paper 1.21.8
• The enableSmootherClientTrident server rule doesn't require a fork of paper with the Noxesium trident patches anymore
