Bukkit

Version 2.3.1

Spigot compatibility: from Spigot 1.8 to 1.13.2
Protocol Lib compatibility: v4.1.0 or higher

( ! ) Upgrading to 1.13 from previous versions

Floating icons inside holograms may not work (they will display as bedrock) because Material names have been changed. You will need to manually update them. You can find a list of valid Material names here (you can't use the ones with the prefix "LEGACY_"):

Changes in 2.3.1

• * Fixed an error with Protocol Lib temporary players (used by other plugins)

• + Added support for Spigot 1.13 and 1.13.2
