Big compatibility update on this one.

• Rebuilt and verified Kits Crates+ for Spigot 1.21.1 through the latest current Spigot release
• Confirmed the plugin is still building cleanly on the older 1.21.1 API target for backward compatibility
• Also verified clean compile support against the newest available Spigot API/release line
• No planned regressions to current 1.21.x functionality
• This update is mainly to keep the plugin safe and current across the newer Spigot versions without dropping support for the earlier 1.21 builds

Recommended:

• 1.21.1+ supported
• Latest Spigot release supported
• Use the proper Java version for your server version when updating
  

Important runtime note:

• 1.21.x needs Java 21+
• 26.1.x needs Java 25+ per Spigot’s March 24 / April 9, 2026 release post
