XSeries (11.0.0) - XSeries removed methods for matching material integer ids. IBuilder has mirrored this change and dropped the constructor support for integer ids.
NBT-API (2.13.0) - No breaking changes
Other Changes:
The KamiCommon class has been mostly migrated to PluginSource. KamiCommon is now just a loader when spigot-jar is installed on a server.
For developers who wish to use KamiCommon without a depend (shading it into your own library) - you can now shade the spigot-jar module and use PluginSource.onEnable/onDisable to enable KamiCommon on your own.
